How do I install ffmpeg from Synaptic without getting a broken package error message? Why am I not able to upgrade these three packages? How do I fix that problem? 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. 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 had the idea to just uninstall those three packages, and then try reinstalling them, but…. Sudo apt upgrade gives this result: The following packages have been kept back:Ġ upgraded, 0 newly installed, 0 to remove and 2 not upgraded. Sudo apt list –upgradable gives this result: libavcodec58/bionic 7:4.3-2~18.04.york0 amd64 But when I mark it for installation, it gets the red exclamation mark indicating a broken package.Īs 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. So, I tried installing ffmpeg via Synaptic.

I used to have ffmpeg installed on my system, but somehow – I don’t know how or when – it got uninstalled.
