Greetings,
After the installation of software or updates, the cache
/var/cache/apt/archives is purged immediately. I tried without success
to get information, which file in /etc/apt/apt.conf.d should be
modified or added... Could you please give me a hint, what to do to
keep the files in /var/cache/apt/archives?
Many thanks! Best regards,
François

You did not say how you upgraded or installed software
By default "apt-get" behaves different, than "apt" does, you temporarily
could change the default by adding "-o <a class="moz-txt-link-freetext" href="APT::Keep-Downloaded-Packages=1">APT::Keep-Downloaded-Packages=1</a>"
or permanently change the behaviour by editing the apt settings. I
don't have at hand how to permanently edit the settings, Google is your
friend.
IOW running
sudo apt full-upgrade -o <a class="moz-txt-link-freetext" href="APT::Keep-Downloaded-Packages=1">APT::Keep-Downloaded-Packages=1</a>
sudo apt install -o <a class="moz-txt-link-freetext" href="APT::Keep-Downloaded-Packages=1">APT::Keep-Downloaded-Packages=1</a> <package>
does the same as
sudo apt-get dist-upgrade
sudo apt-get install <package>
Regards,
Ralf
