I used to have ffmpeg installed on my system, but somehow – I don’t know how or when – it got uninstalled. So, I tried installing ffmpeg via Synaptic. But when I mark it for installation, it gets the red exclamation mark indicating a broken package.
As I looked into this, I also discovered that in the past few days my system says that I have three packages that are “kept back”, and, although the system says they are ready to be updated, they never do update. The three packages are:
libavcodec58
libavutil56
libswresample3
sudo apt list –upgradable gives this result:
libavcodec58/bionic 7:4.3-2~18.04.york0 amd64 [upgradable from: 7:4.1.3-0ppa1~18.04]
libavutil56/bionic 7:4.3-2~18.04.york0 amd64 [upgradable from: 7:4.1.3-0ppa1~18.04]
libswresample3/bionic 7:4.3-2~18.04.york0 amd64 [upgradable from: 7:4.1.3-0ppa1~18.04]
sudo apt upgrade gives this result:
The following packages have been kept back:
libavutil56 libswresample3
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.
I had the idea to just uninstall those three packages, and then try reinstalling them, but….. I didn’t do that, uninstalling any one of them via Synaptic gave me a message that a LONG list of packages would also be uninstalled – basically, every multimedia application I have, such as Audacity, VLC, etc.
I’ve been reading LOTS of answers to others’ questions on this and other sites, but unfortunately they all leave me even more confused about what is wrong and what to do. So, I turn here for help.
Why am I not able to upgrade these three packages? How do I fix that problem?
How do I install ffmpeg from Synaptic without getting a broken package error message?

You have to purge problematic PPAs by
and then install all possible updates with newest dependencies by
and finally install
ffmpegpackage from official repository by
