[Bug 1611737] Re: Can't upgrade from a release if ros packages are installed from ROS servers

[Brian Murray]

I installed the ros-kinetic-ros-base package for ROS on an Ubuntu 16.04
LTS system and started an upgrade with the version of ubuntu-release-
upgrader from -proposed and was presented with the following message:

The Robot Operating System (ROS) is installed

It appears that ROS is currently installed. Each ROS release is very 
strict about the versions of Ubuntu it supports, and Ubuntu upgrades 
can fail if that guidance isn't followed. Before continuing, please 
either uninstall ROS, or ensure the ROS release you have installed 
supports the version of Ubuntu to which you're upgrading. 

For ROS 1 releases, refer to REP 3: 
https://www.ros.org/reps/rep-0003.html 

For ROS 2 releases, refer to REP 2000: 
https://www.ros.org/reps/rep-2000.html 

Are you sure you want to continue?

Subsequently, I'm setting the tags to verification-done.

** Tags removed: verification-needed verification-needed-bionic

Hello Pushin, or anyone else affected,

Accepted ubuntu-release-upgrader into bionic-proposed. The package will
build now and be available at https://launchpad.net/ubuntu/+source
/ubuntu-release-upgrader/1:18.04.41 in a few hours, and then in the
-proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

[Kyle Fazzari]

Note that upgrades to a given release uses the upgrader from that
release. As a result, there's no need to SRU this to Xenial, since
Xenial-to-Bionic upgrades will use the one from Bionic.

[Bug 1611737] Re: Can't upgrade from a release if ros packages are installed from ROS servers

[Brian Murray]

I downloaded the release-upgrader tarball from
http://archive.ubuntu.com/ubuntu/dists/focal-proposed/main/dist-
upgrader-all/current/ (which is necessary because you can't use do-
release-upgrade with -d and -p). I then tried an upgrade having
installed 'ros-melodic-ros-base' and was presented with the following
message:

The Robot Operating System (ROS) is installed

It appears that ROS is currently installed. Each ROS release is very 
strict about the versions of Ubuntu it supports, and Ubuntu upgrades

+  * ROS releases are strict about the Ubuntu releases they support. These
+ days a given ROS release only supports one Ubuntu LTS.
+ 
+  * Attempting to upgrade Ubuntu beyond that supported release at best
+ results in an unsupported situation, and at worst is known to break the
+ upgrade process as it's possible to get apt into an unrecoverable
+ situation.
+ 
+  * The fix for this issue is to detect if ROS is installed and make sure
+ the user is aware that this may not succeed.
+ 
+ [Test Case]
+ 
+  * The dependency problems that lead to apt breakage is very deep and
+ hard to duplicate, but to paint with a broad brush: if a ROS package is
+ installed, extreme caution should be exercised when upgrading as it's
+ very likely that it's not supported.
+ 
+  * To install ROS, follow the proper tutorial for your Ubuntu version, and 
install the "ros-base" metapackage:
+- Xenial: https://wiki.ros.org/kinetic/Installation/Ubuntu
+- Bionic: https://wiki.ros.org/melodic/Installation/Ubuntu
+- Focal: https://wiki.ros.org/noetic/Installation/Ubuntu
+ 
+  * Now use ubuntu-release-upgrader to upgrade to the next Ubuntu
+ release. Such a thing should not happen without prompting the user that
+ ROS is installed and that this may lead to problems.
+ 
+ [Regression Potential]
+ 
+  * Detecting that ROS is installed is done with a package name
+ heuristic, which isn't perfect. We look for a set of base ROS
+ dependencies using a pattern that is unlikely to clash with a non-ROS-
+ related package, but it's possible for this to result in a false
+ positive. Worst case, the user will be warned that ROS is installed when
+ in fact it isn't, but they'll still be able to continue the upgrade.

[Bug 1611737] Re: Can't upgrade from a release if ros packages are installed from ROS servers

[Kyle Fazzari]

> This makes some upgrades technically not possible since there could
not be packages in the ROS repositories available for the new
distribution in an upgrade process. For example, there is no a single
ROS Release that support 14.04 and 16.04. I can not see a
safe/straightforward upgrade path.

Jose hit this on the head. This is explicitly not supported by ROS. The
problem is, Ubuntu doesn't really have a way of knowing that. I think
the best solution to this issue is a nice error message from the
upgrader. We can detect that ROS is installed, mention that an upgrade
isn't supported, and suggest removing the ROS distro before proceeding.

That said, I'm not familiar with the upgrader. Is there supported way we
could hook such logic in?

Re: [Bug 1611737] Re: Can't upgrade from a release if ros packages are installed from ROS servers

[Jean-Marc Le Peuvedic]

Thanks to all. I removed a bunch of packages related to ROS and managed to
perform the update. Some issues linked to deep system level changes. 18.04
has more than one way of going a few things, and which one is used depends
on history, server or desktop release ...

Thanks Jishnu for the information. Much appreciated. I ended up doing a
fresh install of 18.04 and ROS.

[Bug 1611737] Re: Can't upgrade from a release if ros packages are installed from ROS servers

[Jishnu Mohan P R]

I had the same error and I solved it.

First remove ros using the command:  sudo apt-get remove ros-*

If you have created any workspace you have to remove that too.

If you have added setup scripts to you .bashrc then remove that too. For that 
use the command: 
gedit .bashrc 

and then remove all the last commands with ros and your workspaces.

After doing these steps, use the commands:  sudo apt-get clean and sudo
apt-get autoclean

This will solve the error.

[SHAHBAZ KHAN]

Hey Zouhair,
So as to remove the broken packages, I used the following set of commands
sudo apt autoremove, sudo apt purge, sudo apt autoclean.

Hope this may work with you!

[Bug 1611737] Re: Can't upgrade from a release if ros packages are installed from ROS servers

[SHAHBAZ KHAN]

Hey all,
I was facing the same problem. On researching long, I found reason for the 
cancellation of upgrade was the presence of broken packages. These packages 
were of ROS as well as of some other softwares. So simply remove those broken 
packages and then try to upgrade your OS. It will work.

Thanks,
Shahbaz

Re: [Bug 1611737] Re: Can't upgrade from a release if ros packages are installed from ROS servers

[decoder]

Thanks, I already on 18.04. After uninstalling ROS, do-release-upgrade -d
starts works properly. But there is an another problem in upgrade proccess.
I have zfs raid as data storage. And after rebuting new kernel was unable
to load. Problem solves by by buting in old kernel and export-uninstall zfs
and install-import in new kernel.
Thanks for help with ROS packages!

[Bug 1611737] Re: Can't upgrade from a release if ros packages are installed from ROS servers

[Jose Luis Rivero]

Before going down into particular cases, I would like to point that
every ROS Release supports only a few subset of the Ubuntu distributions
(see REP3 http://www.ros.org/reps/rep-0003.html#platforms-by-
distribution).

This makes some upgrades technically not possible since there could not
be packages in the ROS repositories available for the new distribution
in an upgrade process. For example, there is no a single ROS Release
that support 14.04 and 16.04. I can not see a safe/straightforward
upgrade path.

If this is not the case, from Open Robotics we are happy help if
something can be done in ROS packages or repositories.
