Hi, For reasons unknown to me, synaptic uninstalled itself about three weeks ago. I am using Buster on the desktop, with MATE as my desktop environment.
When i open up a terminal and try to re-install it, i get the following- # apt update Hit:1 http://ftp.us.debian.org/debian buster InRelease Hit:2 http://ftp.us.debian.org/debian buster-updates InRelease Hit:3 http://security.debian.org/debian-security buster/updates InRelease Reading package lists... Done Building dependency tree Reading state information... Done All packages are up to date. # apt install synaptic Reading package lists... Done Building dependency tree Reading state information... Done Package synaptic is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'synaptic' has no installation candidate /etc/apt/sources.list is the following- deb http://ftp.us.debian.org/debian/ buster main contrib non-free deb-src http://ftp.us.debian.org/debian/ buster main contrib non-free deb http://ftp.us.debian.org/debian/ buster-updates main contrib non-free deb-src http://ftp.us.debian.org/debian/ buster-updates main contrib non-free deb http://security.debian.org/debian-security/ buster/updates main contrib non-free deb-src http://security.debian.org/debian-security/ buster/updates main contrib non-free I like using a GUI frontend to apt, and if anyone can help me get it back on my system i'd really appreciate it. Thank you in advance for any help that may be provided. - Kieran
