Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[Lorenzo-Outlook]

Thanks Ben

It is true, with the repo 'ubuntugis' the version of QGIS 3.10.2 is not the 
most recent but the libraries are definitely newer, GDAL 3.0.2 and PROJ4 6.2.1. 
It is a bit confusing that since the repo 'ubuntu' the QGIS 3.12.0 version is 
the most recent while the libraries are much less recent and the repo 'ltr' 
also has the older libraries but anyway for now I could work on different 
virtual machines. Of course in some cases I have compiled the libraries too but 
with QGIS there are many libraries connected and I prefer to rely on stable or 
unstable repos. When the new operating system 20.04 will arrive maybe it will 
be better to update to have everything updated.

Thanks again
Lorenzo

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[Ben Hur Pintor]

Hi Harrissou,

Thanks for this! I've been meaning to try the flatpak version for a while
now. Is it stable? Have you encountered any limitations/difficulties with
it (aside from the large size, I suppose)? I might try using it while
waiting for Focal.


All the best,
Ben Hur

Hi,
If i may, I'm also a Ubuntu 18.04 user but I do not use the qgis repo. I
use the Flatpak installation (
https://qgis.org/en/site/forusers/alldownloads.html#flatpak) and with the
3.10.3ltr, i have gdal 3.0.4 and proj 6.3.1

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[Ben Hur Pintor]

Hi Lorenzo,

Ubuntu and QGIS user here as well. I use the ubuntugis-unstable for the
most recent libraries on Bionic (w/o needing to compile the libs myself).
I'm currently still on 3.10.2 since that's the most recent version in the
unstable PPA (w/ GDAL 3.0.2 and PROJ 6.2.1).

For Ubuntu, the ubuntugis-unstable PPA usually contains the most recent
library versions available. The main (universe) repos rarely update
themselves. Which is why GDAL 3.X and Proj 6.X is available via the
unstable PPA and not the main repo.

One thing you can do is compile the libraries yourself for Bionic.

Another is to wait for ubuntugis-unstable to update their packages.

Another is to wait for Focal (20.04) to be released. Based on the
development docs of focal, it'll be released with GDAL 3.0.4 (
https://launchpad.net/ubuntu/focal/+source/gdal) and  PROJ 6.3.1 (
https://launchpad.net/ubuntu/focal/+source/proj) which looks great for
running the recent LRs and LTRs of QGIS.

You can see the note on the QGIS documentation here (
https://qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu)


All the best,
Ben Hur

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[Lorenzo-Outlook]

Thank you very much!
I completely removed the previous installation of QGIS 3.12 and installed the 
LTR release QGIS 3.10.3 using 'qgis.org/ubuntu-ltr'. I also installed the 
server version and now everything works. Great.
Looking at the libraries used for QGIS I see that there is still GDAL 2.2.3 and 
PROJ4 4.9.3. Is there any hope to see these libraries updated to version 3.x 
for GDAL and 6.x for PROJ4 in Ubuntu 18.04?
Thanks again

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[Lorenzo-Outlook]

Hi all
I also was able to install the new version 3.12 in Ubuntu 18.04 following the 
instructions by eliminating the ubuntugis repo. But QGIS is not complete: the 
problem is strange because QGIS opens and inside it is missing many CRS 
projections (for example the geographical WGS84, EPSG:4326 or 3857 and others). 
It seems that the PROJ4 library version 4.9.3 with which QGIS is compiled does 
not contain some CRS. Everything else works but without these projections QGIS 
is not much need. Of course the server version also has this problem and is 
therefore unusable. I went back to the ubuntugis repo and reinstalled QGIS 
3.10.2 which works fine.
Did someone have the same problem or did it just happen to me?
Bye
Lorenzo

[J. M]

Success!! I erased the four offending repositories and the
installation went ahead fine. It installed the latest version (3.12?) which
I didn't expect, and it appears to work on my OS. I ran apt-cache policy
libgdal20 and it returned 2.2.3, so that's perfect. I'll have to enable it
somehow in Blender, but that's another problem.

My profound thanks to the team for helping me; you're incredible!

Cheers,
Jimi.

The first one should be ok.

You can install gdal-bin later from the main Ubuntu repo, which will be 
version 2.2.3. Blender should be happy with it. I doubt they support 
GDAL 3 yet.





So once those four files are removed I can try sudo apt-get install

Run the apt-cache policy libgdal20 again. If it offers you version 2.2.3 
only, then QGIS sould install properly.

GDAL is what is being used to access raster and vector files. 

ubuntugis provides more uptodate packages including GDAL and PRØJ.  So to use
those we normally have also qgis builds based on ubuntugis in
https://qgis.org/ubuntugis next to those for the plain ubuntu release in
https://qgis.org/ubuntu.  The former also requires adding the ubuntugis
unstable repository.

Currently we can work with GDAL2 from plain ubuntu and although we could work
with GDAL3, we cannot use GDAL 3 from ubuntugis, because we also require PRØJ
6.3.1 and ubuntugis only provides 6.2.1.

So there are no current builds for ubuntugis and therefore for bionic you
should remove all the packages you installed from https://qgis.org/ubuntugis or
the ubuntugis repo and install from https://qgis.org/ubuntu instead.

Hi Andre,

Okay thanks once again... I'll have a go, though I'm not sure how to remove
them. Would it be 'sudo apt-get remove gdal-bin' or does it need 'sudo
apt-get remove gdal-bin 3.0.2+dfsg-1~bionic2'? I ask because I don't know

removing them without being sure of the syntax first. Can I be sure they
aren't needed for another program, for example Blender?

So once those four files are removed I can try sudo apt-get install
libgdal20=2.2.3+dfsg-2 again? And once I have libgdal20 installed then I
can run sudo apt-get install qgis qgis-plugin-grass python3-qgis? If I'm
missing anything else then please let me know..

Cheers,
Jimi.

GDAL is more or less the heartbeat of QGIS. Almost every operation uses 
it. For some reason, you must use exactly the same GDAL version as the 
QGIS package is compiled against. For bionic (without ubuntugis), this 
is GDAL 2.2.3. The gdal-abi package is used to confirm that version.


With the Ubuntugis PPA, you have installed a newer version of GDAL

Hi Ismail!

Thanks for your help; your instructions were very clear. I had another go
and it still doesn't work! Haha, I'll end up calling NASA or something..

Here's what I get:
sudo apt-get remove libgdal20
[sudo] password for jimi:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package 'libgdal20' is not installed, so not removed
0 to upgrade, 0 to newly install, 0 to remove and 57 not to upgrade.

amd64Geospatial Data Abstraction Library
ii  python3-gdal   3.0.2+dfsg-1~bionic2

Abstraction Library

The package I was trying to install was actually libgdal20, following
Andre's last suggestion:
sudo apt-get install libgdal20=2.2.3+dfsg-2

I'm still not clear about what the ubuntugis PPA is needed for, or what
gdal even is.. It probably seems like I'm emailing with every problem, but
each time I do it's after I've spent an hour googling things and trying
stuff. I'm really struggling to understand why QGIS is so dispersed, and
why I can't isolate everything and purge it for a clean reinstall..

Any further help would be greatly appreciated because I'm completely out of
ideas.
Cheers,
Jimi.

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[Ismail Sunni]

Hi Jimi,

Since I have more or less the same problem, I did like this:


   1. Set to use the ubuntu repo in your APT:
   deb https://qgis.org/ubuntu bionic main
   deb-src https://qgis.org/ubuntu bionic main
   2. Try to install QGIS or any packages that you need.
   3. If you get the `The following packages have unmet dependencies.`
   problem, just remove the package. For example in your case `libgdal20`
   (sudo apt remove libgdal20).
   4. If the package is not found, try to find the package name, for
   example by using `dpkg -l | grep gdal`. Remove the packages.
   5. Try again to install your package (from step 2), see if the problem
   persists.

In my case, I got this The following packages have unmet dependencies when
I want to install QGIS, then QGIS requirement for building from source. I
got missing saga-common, gdalabi, and libopencv-calib3d3.2.

I did the steps above, and now it works fine.

Basically, what I understand is, there is a problem in the package, so
remove it, and the package manager will re-install it while you are
installing QGIS. CMIIW.

I hope it helps.

Best regards.

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[J. M]

Hi there guys,

I think I've done everything that people have suggested, including Andre's
last suggestion:
sudo apt-get install libgdal20=2.2.3+dfsg-2, which returned this, similar
to last time:

sudo apt-get install libgdal20=2.2.3+dfsg-2
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies.
 libgdal20 : Depends: libogdi3.2 (>= 3.2.0) but it is not going to be
installed
E: Unable to correct problems, you have held broken packages.

As I can't get beyond that point I have no idea what else to try, to be
honest. As Ben suggested I edited the etc file to include this:
deb https://qgis.org/ubuntu-ltr bionic main, because Ubuntu 18.04 LTS
doesn't yet support QGIS 3.12. If you can install QGIS and run it, then how
do you simply remove the entire program and all its dependencies so that
you can start from scratch? If I run purge X on any other program I think
my system removes it completely, though I'm not sure.

Fernando Moxo suggested the following, but I've already run sudo apt-get
autoremove qgis (as QGIS wasn't the last program I installed and I don't
want this process to randomly erase vital dependencies and leave me with
half an OS) and there are fewer unmet dependencies now than the first time,
but I don't know what 'installed prereq.' means, or 'Id those prereq'.
Sorry, I can't act on that line because I don't understand it.

sudo apt autoremove

Should uninstall all dangling installed prereq.   Id those prereq are
being kept due to some other package requiring them, or some remaining
from previous Qgis install it can take a bit more effort to fix.


I don't know how to erase individual dependencies, so without specific
commands I wouldn't know where to start. I ran autoremove and I thought it
took out everything, even dependencies unrelated to QGIS. Out of curiosity,
are the majority of QGIS users software developers as well? I've never
experienced this level of technical difficulty associated with the
installation of a piece of software on Linux before (I've been a dedicated
Ubuntu user since 12.04 LTS).

Could someone recommend where to start from scratch, and suggest what to do
step-by-step, so I'm not cluttering up the group email with the same
queries for ages? I had it working perfectly (albeit briefly) before I
accidentally installed the ubuntugis-unstable PPA, so I know it's not a
problem with my OS.
Many thanks again,
Jimi.

  This kind of error usually indicates that 3.12 is already
installed.  Prossibly a previous install brought in the 3.12 version as
a pre-requirement.   If that is so, a command like:

$ sudo apt autoremove

Should uninstall all dangling installed prereq.   Id those prereq are
being kept due to some other package requiring them, or some remaining
from previous Qgis install it can take a bit more effort to fix.

  Try to remove directly each of those dependencies.

No, thats wrong. From

Usually, "sudo apt-get update" should clear the cache. Maybe you need to

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[J. M]

Hi guys!

Well thanks for all that info! Ben, I completely failed to understand what
you explained before about your OS, but I get it now! I was happy with 3.10
anyway, so that's great. I'll have a go at removing ubuntugis-unstable and
I'll edit my source file accordingly. Incidentally, it might be a good idea
to explain that on the site because I've been redirected there many times
and always just gone somewhere else to get instructions about what to do.
For software engineers it's maybe logical, but for end users like me it
seemed like reference information, entirely unrelated to the actual
installation process.

Andre, thanks again! I'm not sure how to remove the ubuntugis files to be
honest, if purging QGIS doesn't work. I erased the GPG manually (sudo
nautilus) because I hadn't encountered an easy way, but then I ran
autoremove qgis and I thought that would take care of everything related to
it, including PPA's (the command removed stuff connected with FreeCAD, for
example, which has no connection whatsoever).
The key is for the whole ubuntugis project, regardless of the branch you
are using. Same goes for QGIS.
That makes sense, and explains the error message about it.

Okay, one last question:
And add "python3-qgis" to your install command.
I don't know enough about linux syntax to include this without dropping the
ball.
Maybe 'sudo apt-get install qgis qgis-plugin-grass python3-qgis'?
Should I start again and run autoremove qgis, etc, or can I attempt it from
where I am?

Thanks again!!
Jimi.

I guess you are better off without anything from ubuntugis at the

You should run "apt-cache policy libgdal20" to see that you have GDAL

Seems to be a non-ubuntugis package, but You don't have the GDAL version

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[Ben Hur Pintor]

Hi!

It looks like your machine is trying to install 3.12.

As I mentioned in the last part of my previous message, right now you can't
install QGIS 3.12 on Ubuntu 18.04 because 3.12 needs PROJ 6.3.1 which
currently isn't available in Bionic -- via the main canonical repo or even
with the ubuntugis-unstable PPA. Therefore, I suggest installing from the
LTR branch and not the LR branch. When I use the LTR branch with ubuntugis
dependencies, I get QGIS 3 10.2 no problem.

I run the same machine as you and actually faced the same problem when I
tried to install the Latest Release (3.12) on Bionic. Try using the repos
for the LTR (the ones with -ltr in the end). Maybe that will help.

Don't worry about it, we've all been there.


All the best,
Ben Hur

Hi Ben,

No joy, I'm afraid. I think I did everything you recommended. I'm going to
run through it in case I missed something obvious:

   - I ran sudo apt remove qgis grass qgis-plugin-grass, then ran sudo
   apt-get update
   - The /etc/apt/sources file contains the correct info because I modified
   it for the last installation
   - I ran autoremove on QGIS and erased over a gigabyte of
   dependencies (which seemed like a *lot*..)
   - I ran sudo apt-key list to check if the ubuntugis-unstable PPA was
   still listed as trusted, and it didn't appear
   - I added the ubuntugis stable PPA as recommended on
   https://trac.osgeo.org/ubuntugis/wiki/UbuntuGISRepository, with sudo
   add-apt-repository ppa:ubuntugis/ppa, and it appeared to duplicate your
   command sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key
   51F523511C7028C3. Is that possible when they appear to reference two
   different PPA's?
   - I ran sudo apt-get install qgis qgis-plugin-grass and received the
   following error message, similar to before:

The following packages have unmet dependencies.

I must be missing something. Do I have to open the UI via terminal (sudo
nautilus) and manually remove every file which makes reference to QGIS and
ubuntugis-unstable? As formatting my machine isn't an option there must be
a simple way of completely removing the program and its dependencies..
right?!

I don't even know what Gdal is or does, because I can't even get started
learning QGIS because I'm finding it impossible to have a version running
for long enough to start with tutorials! Is it to allow you to overlay
raster info onto GIS projects or something? I googled it but the
explanation must have been written by a robot (no offence intended, to

because Blender gave me the helpful error message: Please install gdal to

Hi Ben!

Thanks a lot for that, really helpful; I'll give it a go. It was actually
the ubuntugis unstable PPA which caused the current problem I'm having, so
I'm keen to avoid that PPA if I can. I'll try your steps again and let you
know what the outcome is.

Cheers,
Jimi.

Sorry, that sent accidentally. I'll give it a go. It was actually the

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[Ben Hur Pintor]

Hi!

First of all, make sure that you add the qgis.org repo public key via sudo
apt-key adv --keyserver keyserver.ubuntu.com --recv-key 51F523511C7028C3.
Make sure that the library versions in your computer (specially GDAL and
PROJ) are the same libraries that QGIS is built against.

The links in
https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu determine
which versions of QGIS will be installed. You add these as sources in the
Software Center or you can add them directly in your /etc/apt/sources.list
file as instructed in
https://qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu.
If you want 3.12 (Latest Release), you can use/add the following in your
/etc/apt/sources.list file https://qgis.org/ubuntu or
https://qgis.org/ubuntugis (if with ubuntugis-unstable dependencies).
If you want the LTR branch (3.10.3), simply use https://qgis.org/ubuntu-ltr
 or https://qgis.org/ubuntugis-ltr (if with ubuntugis-unstable
dependencies) in your /etc/apt/sources.list file.

Also, don't forget to remove/purge all previous QGIS or GRASS installations
(e.g. sudo apt remove qgis grass qgis-plugin-grass) and do an update (sudo
apt update) before trying to install QGIS again.

I run Pop! OS 18.04 (based on Ubuntu 18.04). Unfortunately, the libraries
in the main (universe) repo of Bionic are a bit outdated (GDAL 2.2.3, PROJ
4.9, etc.). The newer versions of QGIS use GDAL 3.0.X and PROJ 6.X. Using
the ubuntugis-unstable (
https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable) PPA
remedies the problem of some outdated libraries. If you will use the
ubuntugis-unstable libraries, don't forget to add the PPA to your sources
as well. On another note, PROJ 6.3.1, which QGIS 3.10.3 and 3.12 use, isn't
available yet in Bionic even when using the ubuntugis PPA so even if I
want, I can only install 3.10.2 right now on my machine. Trying to install
3.12 via the ubuntu or ubuntugis repo fails.


All the best,
Ben Hur

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[J. M]

Hi Ismail,

Well, I've tried everything I can think of, everything people have
recommended and everything I've googled, but there seems to be no earthly
way to get rid of the following error messages:

sudo apt-get install qgis qgis-plugin-grass
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies.
 qgis : Depends: python3-qgis (= 1:3.12.0+28bionic) but it is not going to
be installed
E: Unable to correct problems, you have held broken packages.

I've tried this:

sudo apt-get purge qgis
sudo apt-get autoremove qgis
sudo apt-get --purge remove qgis
sudo apt-get update

 but it returned the following:

sudo apt-get update

I can't think of anything else. Any suggestions about what I might be doing
wrong? I don't actually understand what this link is for:
https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu
If you download via the terminal by typing 'sudo apt-get install qgis' then
how do you make use of all the folders in this link? I mean, how do I
differentiate if I want to download version 3.10 or 3.12 of QGIS?

Sorry team, I just can't get this to work and I'm worried I do irreparable
damage to my system with this process.
Please help me out, guys!
Cheers,
Jimi.

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[Alex Mandel]

Keep in mind when using PPAs you can easily remove them with ppa-purge
(see #4 on
https://itsfoss.com/how-to-remove-or-delete-ppas-quick-tip/
)

You might need to drop your PPAs, revert back to the default versions of
QGIS, then add back in the repos you need.

Thanks,
Alex

 Yes, because you have packages that are compiled against a set of
 libraries that does not match your computer. You have to remove,
 autoremove and purge those QGIS packages to force a download from the
 right folder.

 That should go into your sources list, to replace the QGIS download
 source you used before. The Ubuntu Software center has a tab for "other
 Software" that holds the same information, so no need to edit the
 sources file manually.

Hi Ismail!

Many thanks for your advice; I'll check it out. I haven't actually had a
chance to sit down and try to purge QGIS and start again. Andre was trying
to help me but I wasn't sure where to start so I haven't tried since I last
inquired about the process!

Thanks a lot,
Jimi.

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

Hi Jimi,

I have a similar problem. I fix it by reinstalling gdal (libgdal20). I can
install QGIS again after that. But, I am not an expert with this package
manager thing, so perhaps it can work for you also, or perhaps not :)

While trying to fix my problem, I found this
https://askubuntu.com/questions/140246/how-do-i-resolve-unmet-dependencies-after-adding-a-ppa
which
probably useful for you.

Best regards

Re: [Qgis-user] QGIS uninstalled after GDAL PPA install

[J. M]

Hi again Andre,

Thanks for that, I more or less get what you mean. The problem is that when
I ran autoremove it came back with almost a gig of dependencies it wanted
to remove, so I cancelled it! QGIS wasn't the last program I installed so I
have no idea how to purge only the dependencies directly related to the
previous version of it I was running. If I run autoremove and it damages
other applications or makes my system unusable then I won't be able to fix
it (I'm only a user, I've got no background in programming). I read around
and people warned strongly against doing this unless you're sure what you
want to remove. How can I be sure I only remove the right dependencies?
Does QGIS have a list or something I can use as a guide?

If anyone could explain how to use Synaptic package manager then I'd be
really grateful! It must have the most unintuitive interface of any piece
of software I've ever tried to use..

I edited the source file last time I installed it, so that part is done.
Incidentally, I don't see the 'other Software' tab in the Ubuntu Software
Center, so I just edited it manually. Any idea what that package is called?
I'm happy enough using the terminal if I know (roughly) what I'm doing!

Thanks a lot team,
Jimi.

Hi again Andre,

I don't actually understand what to do with this, because I can't run 'sudo
apt-get install qgis qgis-plugin-grass' as it keeps giving me the same
error messages about broken packages.
When you say this, I don't get what this link does. I click on it and it
just takes me into a file hierarchy. Are users supposed to obtain the
downloads from here, or is it purely informative?
Try
deb https://qgis.org/ubuntugis bionic main

and it should work.

After re-installing, you should be able to install gdal-bin too.

If you want (or must) to stick to GDAL 2, remove all ubuntugis
references, and take QGIS from the ubuntu repo.You might need to remove
GDAL 3 if you already installed it.

As for removing all ubuntugis references, I have no idea where to start
with that. I opened Synaptic package manager and searched for QGIS, but
there are so many dependencies and related files I have no idea what to
remove before attempting to reinstall it. I still don't understand how
attempting to install the GDAL PPA caused the QGIS to get uninstalled (I
certainly wouldn't have done it if I'd thought it was going to remove the
software). Are there any other operations like this I should be aware of,
updates or similar which can cause QGIS to just disappear? Ideally I'd like
to remove all the repositories and dependencies which aren't strictly
necessary for the current version to run. Is there a way to check the
dependencies needed in the terminal or somewhere and filter out all the
others?

Any help would be greatly appreciated!
Cheers,
Jimi.

Hi Jimi,

Hi team,

Well, this is a bit embarrassing. I've just started working with GIS data
in Blender (BlenderGIS is a great add-on if anyone doesn't know it
already). Anyway, I was trying to add a reference basemap to a Blender
project with polygons in it and I got an error message telling me to
install GDAL. I'm a total novice at both Blender and QGIS, so I read
around and people recommending adding the GDAL PPA in QGIS directly. I did
so following the Linux guidelines here:
https://developers.planet.com/planetschool/gdal-qgis-installation-setup/



This is outdated by a few years. The current setup for QGIS can be found 
here:




You have two choices: With or without the ubuntugis ppa.
The ppa holds GDAL 3.0.2 along with all dependencies.
Without the PPA, you can get GDAL 2.2.3

QGIS supports both channels, using a different folder to download from.



The following packages have unmet dependencies.
  qgis : Depends: gdal-abi-2-2-3



This seems to be the QGIS version without ubuntugis support.

Try
deb https://qgis.org/ubuntugis bionic main

and it should work.

After re-installing, you should be able to install gdal-bin too.

If you want (or must) to stick to GDAL 2, remove all ubuntugis 
references, and take QGIS from the ubuntu repo.You might need to remove 
GDAL 3 if you already installed it.
