The package manager is the system that manage packages(programs or libraries)
Programs are the main files
Libraries are common programs that other programs use.
Command line package management
GUI package management.
The classic here is Synaptic Package manager. It has not been updated since 2015 so for general use try something else
- That said there are times when Synaptic can do thing the others cannot.
In KDE we like the Muon Package Manager.
- It seems pretty current.
As of 22.04 we are moving towards the KDE native discover.
- One obvious error is that it defaults to snaps
- The program Evince(Document Viewer) is an example
- The snap installs
- BUT the print dialog does not give you the very options we like in Evince
- Installing from Muon gives the full print Dialog.
- The program Evince(Document Viewer) is an example
- Otherwise we are moving in this direction.
- It has been 4 years since Muon was updated.
- Which is mainly ok since it is just a front end for apt.
- Which is mainly ok since it is just a front end for apt.
- It has been 4 years since Muon was updated.
Issues
There are a few common things that can go wrong.
Change in PPA Label
This can happen when the developer makes a change to the core files of the PPA
If you use apt-get you will not get the option to accept the change.
The gui will not do this for you.
Option 1:
sudo apt update
Accept the changes.
Option 2:
sudo apt-get update --allow-releaseinfo-change
Broken Password for config
for some reason you can no longer change software sources directly.
Discover
With this fix you can do so in discover. The bug is in progress. Fixed in 22.10 but not 22.04 yet
Muon
To fix the issue with Muon, create the file /etc/sudoers.d/kdesu and write the following line into it:
Defaults!/usr/lib/*/libexec/kf5/kdesu_stub !use_pty
sources: https://www.kubuntuforums.net/forum/currently-supported-releases/kubuntu-22-04-jammy-jellyfish/desktop-environment-support/663217-muon-software-sources-not-working-after-upgrade which references to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1011624 for the solution.
Change the Repository
To change the repository open the sources.list file in /etc/apt/ and change the address of the current repository to the one you want to use. You can find a list of all official archive mirrors for Ubuntu at https://launchpad.net/ubuntu/+archivemirrors.
