You can install all codecs with the command

sudo apt install ubuntu-restricted-extras

Also, the upgrade path was buggy and sometimes it removes many packages present in default ubuntu installation. To reinstall all of them, execute the command

sudo apt install --reinstall ubuntu-desktop^

(Note: The ^ is necessary in the command above)

  • What does the ^ do?

    ubuntu-desktop is not a package, instead it's a task. so the roof char is required to not run into a package not found error. see also askubuntu.com/questions/211912/whats-the-caret-mean-in-apt-get

    Zsh users should quote ubuntu-desktop^ (^ is used as a globbing metacharacter and unquoted unintended ^ will make commands fail at best)

  • For me ubuntu-desktop is a package (metapackage) and it depends on many stuff that makes up the default Ubuntu desktop installation.
