I would suggest dpkg -S instead of apt-file find, which matches prefix, not
exact file. I would also filter on the package name and ensure unicity. Also,
never log in as root.
Here would me my quick & dirty take at your command chain:
find /usr/bin -atime +360 | xargs -l1 sudo dpkg -S | awk -F ':' '{print $1}' |
sort | uniq
Nice command. If found some 76 packages, including, for example, gcc-4.8,
setcd, wmtime...
Thanks to all also for the apt- and debfoster- based methods. They need more
thought.
On the dark side, something bad happened during the upgrade, which I only
realized later:
*pulseaudio* was surreptitiously installed. Beowulf worked well without it,
and Chimaera also worked well as soon as I removed it.
*python* was not installed at all. How come?
Best
Ale

That goes a bit like this sudo apt-mark auto $(apt-mark showmanual) followed by looking at what sudo apt auto-remove would like to get rid of. Make sure to say 'n'! Based on the list of potential removals, I sudo apt-mark manual After iterating a couple of times until I'm happy with the list of stuff that will be removed I finally say 'y' so apt zaps the stuff I don't want/need. The first time around, there will be quite a long list of packages that are candidates for removal. Even without a desktop environment installed the list can be several tens of packages. Look for the "top-level" kind of packages to `apt-mark manual`, things like task-xfce-desktop, so you don't have to add a long list of packages. You can `apt-mark auto` them later and fine-tune your list of manually installed packages. # This is how I whittle down the list of xserver-xorg-video-* packages # that I really need :-) Doing this in phases also gives you a bit of an opportunity to recover from mistakes when you remove a package you actually need without realizing it. Check the /var/log/apt/history.log* files to see what you removed recently if stuff breaks. Options that you might want to pass to that apt auto-remove invocation -o APT::AutoRemove::SuggestsImportant=false -o APT::AutoRemove::RecommendsImportant=false -o APT::Get::Purge=true # Add them to /etc/apt/apt.conf if you want to use these by default. The first is pretty benign. It just removes those packages that are only kept installed because some package has a Suggests: dependency on it. Of course, you might want to keep it. In that case, just say sudo apt-mark manual The second option is similar but ups the ante a bit and tries to get rid of packages that are only installed because they are recommended. As for the Suggests:, use apt-mark manual to keep stuff you want/need and get rid of the rest. The third and final option makes sure any configuration files are removed as well. I keep mine version controlled with etckeeper so zapping config files is typically not an issue for me. The git repo has a copy that I can resurrect as needed. If you do not have backups of configuration files that might be removed, you're probably better of not using this option.

Re: [DNG] Advice to migrate from Beowulf to Chimaera
I would suggest dpkg -S instead of apt-file find, which matches prefix, not exact file. I would also filter on the package name and ensure unicity. Also, never log in as root. It has been brought to my attention I was wrong: dpkg -S doesn't require privileges and runs fine in userland. Hence, scratch that part of my previous message.

Huh? What's with the sudo for dpkg -S?
For all I remember that works fine without root privileges.
olaf@quark:~$ find /usr/bin -atime +360 | xargs -l1 dpkg -S \
| awk -F ':' '{print $1}' | sort | uniq
eject
pciutils
upower
xfconf
FWIW, throwing in sudo gives the same result and my user account is in
the sudo group. And I have modified that groups /etc/sudoers entry to
# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) NOPASSWD: ALL
so it doesn't prompt me for a password.
Hope this helps,

Hi all, I usually prefer to stick on released system, but I'd start working on OpenSCAD and the version available is rather oldish. As it has lots of graphical dependencies, I think it may be easier to switch to Chimaera than to pin all that stuff. I run Openbox, btw. Is there a guide, a wiki, release notes, any help?
