[xubuntu-users] Keeping *.deb in the archive (Ubuntu 16.04.2)

[François P. Rotzinger]

Greetings,
After the installation of software or updates, the cache 
/var/cache/apt/archives is purged immediately. I tried without succes 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
