Codec don't install

[InfoLibre]

I installed Linux Mint MATE 20 64-bit in VirtualBox, without any Ethernet interface. Then, after the installation and the first reboot, Linux Mint proposed me to install the French Language packages and the Multimedia codec packages. French Language packages were installed but the Multimedia codec packages were not, I had this error message :

After installing Ulyana and doing an "apt update && apt upgrade && reboot" the installation through the GUI still fails with the error from the first post. I did not switch to a local mirror before doing this.

Doing a "apt install mint-meta-codecs" does work though without problems and systems reports are not showing the codecs as open problem anymore.

apt install mint-meta-codecs is working too on live USB with partial upgrade. Problem is graphical interface.

It looks like installing mint-meta-codecs brings in libavcodec-extra58, which conflicts with libavcodec58. From the command line, it's happy to just remove libavcodec58, but the GUI might not.

oh yes, haven't see it before ... apt update ... apt install mint-meta-codecs The following additional packages will be installed: cabextract ... Suggested packages: frei0r-plugins ..... The following packages will be REMOVED: libavcodec58 The following NEW packages will be installed: cabextract ... libavcodec-extra58 .... 0 upgraded, 51 newly installed, 1 to remove and 176 not upgraded. Need to get 17.0 MB of archives. After this operation, 30.9 MB of additional disk space will be used. Do you want to continue? [Y/n] y

Confirmed on live DVD, language EN-US. Link to forum post (because blog post wasn't up yet and I didn't know that devs don't check the forums): https://forums.linuxmint.com/viewtopic.php?f=48&t=321910&p=1828242#p1828242
