Somehow you haven't yet cleaned your system from the "orphaned" Debian-Mutimedia packages. At least I don't have another explanation.
You may try the regular methods to repair apt: sudo apt install -f, sudo apt update --fix-missing, sudo dpkg --configure -a etc. It's uncertain they can help in your case. Your software sources should be OK by now. You have orphaned packages installed that block proper resolving of dependencies for packages you want to install.
I have gstreamer-plugins-bad installed in my system. Libchromaprint is one of its dependencies. Executing
apt depends libchromaprint1
to find dependencies for libcromaprint1:
Code: Select all
Depends: libavcodec58
libavcodec-extra58...
It depends either on libavcodec58 or libavcodec-extra58. Latter is installed in my system and not the former. So try
sudo apt install libavcodec-extra58
before installing gstreamer plugins.
If that fails, try to install or force re-installation of the mint codecs meta-package. The way those packages landed into my system I suppose. Perhaps there is some hidden magic in that meta-package.
sudo apt install mint-meta-codecs
or
sudo apt reinstall mint-meta-codecs
.
