As @unman mentioned in the Debian-10-minimal Configuration thread, more up to date packages can be installed to the Debian templates if Debian backports source is added to the /etc/apt/sources.list file. My question is: is it ok to add any lines with http to my source.list? Or if i’d like to make it work with https my only option is an update-VM with apt-cacher-ng installed? When i used a debian based linux, i always tried to find mirrors for the sources.list with https option, and installing the apt-transport-https package, but i’m not sure how does it work in the Qubes OS.
Thanks any help!
