Public bug reported: I have a Lubuntu installation, in which I cannot upgrade because grub2-pc refuses to install. After a while I found that linux- image-4.15.0.38-generic also not installs, but grub2 in the main one, because every apt installation is extremely long, since it tries to install grub2, but it cannot.
