In Ubuntu 20.04 LTS the software updater says there are no available updates, but apt list --upgradable
shows packages that can be upgraded. (I ran the command because I had installed something and then apt said I should.) Update-manager does not show all updates says updates can be phased and it's possible to disable them. Apparently, there are two preferences, Update-Manager::Never-Include-Phased-Updates "True";
and APT::Get::Never-Include-Phased-Updates "True";
. Does that work for Ubuntu 20.04 and will it solve the problem?
$ apt list --upgradable
