I’m a newbie with Picard and I want to work with music on a CD. I noticed that Lookup CD is greyed out. Help > About states that Discid is not installed. How do I get Discid installed on Ubuntu 16.04? BTW, I installed Picard using Flatpak.
You can search for packages in a terminal on the command line with "apt-cache search package-name"

You can install with "sudo apt install package-name":
$sudo apt install libdiscid0
I don’t know about the Flatpak version, but it probably does not include libdiscid. Try installing Picard from PPA, this will use the libdiscid0 package as described above.
Thanks for your responses. I determined the problem was with the Flatpak, so I removed it and reinstalled using the PPA. Now it works.
