Hello!
 
No one has reported me any issues with the contributed code. I suppose it works 
perfectly fixing all the related bugs (listed here: 
https://code.launchpad.net/~jarnos/ppa-purge/+git/ppa-purge/+merge/313001).
You can donate to me on my homepage now. (You can find the link in signature 
below.)If I get support, I'll consider publishing code of linux-purge 
(https://launchpad.net/linux-purge)

Can you give the argument as separate word without '=' ? Or remove the 
character from environment variable COMP_WORDBREAKS
That does not remove the bug, though.

And how does one know, if the script works? I have analyzed many of proposed 
scripts and have noticed problems in them. Maybe they work for you, if you are 
lucky. They might e.g. purge more than you expect.

I have never removed lib/modules by rm, but I seem to have only folders for the 
kernels that I have left installed there in the folder anyway, so I do not see 
the problem. Are you sure apt/dpkg do not handle the DKMS hooks?

The latter is publicly available

Yes, that is how many Ubuntu users spend their time. Hanging on support

I am not making it complex, it is complex. There are many servers for Ubuntu 
software (like you can see in Software & Updates, many of them does not have 
word ubuntu in its domain name. But hopefully user knows what he/she is 
removing, as he/she is probably the one who added the extra repositories in the 
system.

Don't shoot the messenger. I am telling people should pay attention. Though I 
have added simulation mode and recovery function in ppa-purge, so it should be 
safe to experiment.

Please note that there is no way to remove Ubuntu components currently as for 
removing/downgrading packages by ppa-purge.

ppa-purge has had more than one way of giving the repository even before I 
started working on it.

Re: ppa-purge

[Jarno Suni]

Furthermore AFAIK PPA means an APT repository hosted at 
'http://ppa.launchpad.net'. However, ppa-purge allows removing repositories 
hosted in other servers using the ppa form: e.g. 

sudo ppa-purge -s dl.google.com ppa:linux/chrome
or shortly
sudo ppa-purge -s dl.google.com linux/chrome
will catch debline
'deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main'.
For the previous case
ppa-purge -s dl.google.com -o linux -p chrome
works, too. So user gives 'linux' as PPA owner and 'chrome' as PPA name. 
Do these confuse users?

Bash's tab completion works pretty well with the previous ones, except maybe 
with 'ppa:' form, since the colon seems to cause some problems probably due to 
being treated as word separator. I am not sure, is it worth messing with 
COMP_WORDBREAKS variable, though.

"debline" form that add-apt-repository supports, and URL form that 
add-apt-repository supports, too, but that is undocumented, are not currently 
supported by ppa-purge.

I suppose having GNU style long options would make it easier for users to use 
tab completions (and not that much help/manual).

ppa-purge

[Jarno Suni]

I have contributed to ppa-purge a lot this year. It can also remove other 
repositories than Launchpad PPAs. Would it be better to call it 
remove-apt-repository? If not, I suppose I should do a merge proposal. But I 
can't. And I have not received any support lately. Nor any feedback.

Well, there are software developers paid by Canonical; they write code to 
Ubuntu. E.g. 
Michael Vogt who has written unattended-upgrades and some other apt-related 
stuff.

Ubuntu still does not provide satisfactory automatic kernel removal system at 
least by default. Many end users still get their system wrecked due to kernels 
filling the system. Canonical could do something to help users of supported 
Ubuntu releases to deal with the awkward issue easily. Funding my script would 
be one such thing.

I also have considered publishing the script, and linking a donate button 
somewhere. That way people who have benefited from the script and who maybe are 
not contributors themselves could show some gratitude (if they are aware of 
such a button). But if I believe Gunnar Hjalmarsson, they would not pay anyway.

I have tried to make my script safe. Besides it has an optional simulation 
mode: no files or packages will be removed, when using it; the script forces to 
run the simulation mode as normal user. And the script has a bug tracker in 
Launchpad, so people can easily find known issues with the script.

Well, byobu package does not have the script in Trusty; bikeshed has, but even

Partially, yes. My script can purge new kernels, too :P purge-old-kernels is a 
pretty simple script with some bugs and limitations. E.g. 
https://bugs.launchpad.net/byobu/+bug/1569228
though there has been some attempt to fix things in git.

No. I'll possibly get paid by Bountysource only after I have published the code 
and it has been accepted by backers as a solution to the issue. To be more 
specific, refer to

It depends on script 
/etc/kernel/postinst.d/apt-auto-removal and when it is run last time, which 
automatically 
installed kernels it does NOT remove. `apt-get autoremove` removes other 
packages that are automatically installed and that no package depends on, too, 
which may or may not be wanted. It may be unable to remove old kernels in some 
cases when /boot or system is full. My script is designed to handle such cases, 
too. My script can even remove kernels that are unknown to the package 
management system.

My script handles different types of kernels. Including signed kernels.

And you can keep the wanted number of kernels of each series non-interactively 
(and of course interactively). For example, in Trusty, if you have 
linux-image-generic and linux-image-generic-lts-xenial installed, you could 
keep e.g. 3 latest kernels of each series. (The one that the meta kernel 
depends on and 2 earlier versions, if installed.) `purge-old-kernels` and 
`apt-get autoremove` do not have this feature.

My script does not care about dkms, if that is not done automatically by 
standard tools. I don't know what kind of care you mean.

Re: Adding a kernel removal script to linux-base or elsewhere

[Jarno Suni]

Hello!

What is the recommended way to publish the script? I guess Launchpad would be 
the right place. And using Git repository might be a good idea. I have got a 
Launchpad account (jarnos). Is it better to create a project in Launchpad or to 
create a PPA? Detailed instruction would be welcome.

Re: Adding a kernel removal script to linux-base or elsewhere

[Jarno Suni]

Here is some update. My script does not use linux-version anymore. But I named 
the script linux-purge. It can remove kernels even in some problem cases where 
e.g. there are dependency problems due to an unsuccessful kernel update (e.g. 
due to full /boot partition). It provides optional UI for interactive checklist 
based kernel removal. It does not support kfreebsd-image and gnumach-image 
kernels, but only Linux kernels and it is designed to work in any flavor of 
Ubuntu.
Here is a demo that shows it in action: 
https://youtu.be/TpsZoAnOVTU

I have not published the script yet, but maybe later, if there is enough 
interest.

Dropbox wants to update

[Jarno Suni]

Hi

I have installed nautilus-dropbox on Trusty. Now it tells I have to update in 
order to continue using the product. If I follow instructions, I am guided to 
install a .deb that conflicts nautilus-dropbox. How to proceed?

Adding a kernel removal script to linux-base or elsewhere

[Jarno Suni]

Now that linux-base is part of .?ubuntu 16.04, I think it would be good to add 
a linux-kernel removal tool to linux-base. On the other hand, I think such a 
script is especially useful for some older releases, since e.g. Trusty tends to 
mark kernel updates as being manually installed packages and as such 'apt-get 
autoremove --purge' can not purge them. (
https://bugs.launchpad.net/ubuntu/vivid/+source/aptdaemon/+bug/1439769
https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1492709
https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1175637)
If automatic removal of unneeded kernels is not enabled, /boot fills up, and 
blocks kernel updates:
https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1054927

There is purge-old-kernels currently at byobu repository, but maybe it is too 
simple, and has some bugs:
https://bugs.launchpad.net/byobu/+bug/1569228
https://bugs.launchpad.net/bikeshed/+bug/1532153
I have rewritten it to fix those at 

https://github.com/dustinkirkland/bikeshed/pull/1
when purge-old-kernels was located at bikeshed, and as I have written in the 
(last) comment: "I have written an enhanced script for similar purpose again, 
but maybe it is not good to call it purge-old-kernels, since it can be used to 
purge newer kernels, too (but keeping the kernels that installed kernel meta 
packages depend on and given number of older ones). It currently uses 
linux-version from linux-base package to sort kernel releases as needed. I am 
looking for a suitable place to publish the bash script."

Finding meta kernel packages is problematic. I have used regular expression 
matching the package names: 
http://askubuntu.com/q/775830/21005It seems to work in Ubuntu, but not in 
Debian as such, I think. Also getting versioned kernels (and packages related 
to kernel of specific release) may be problematic in general:
https://lists.debian.org/deity/2016/05/msg00115.html

So how about adding some ubuntu-purge, linux-purge or kernel-purge in 
linux-base? Should it support 
kfreebsd-image and gnumach-image that are listed by "apt-config dump"?
