[Bug 1826585] Re: I can't update, upgrade or autoremove

[C de-Avillez]

OK. I see you have corrected the system date.

Two points here:

1. you should use 'apt full-upgrade'. There is a difference in behaviour
between 'upgrade' and 'full-upgrade'. the following is an excerpt from
'man apt':

       upgrade (apt-get(8))
           upgrade is used to install available upgrades of all packages currently installed on the system from the sources configured via sources.list(5). New packages will be installed if required to satisfy dependencies, but existing
           packages will never be removed. If an upgrade for a package requires the removal of an installed package the upgrade for this package isn't performed.

       full-upgrade (apt-get(8))
           full-upgrade performs the function of upgrade but will remove currently installed packages if this is needed to upgrade the system as a whole.


2. it is apt-cache, not apt-caShe. And 'apt-cache show' requires at least one package name -- see 'man apt-cache' for details.
