I am porting my (limited) stuff to Ubuntu 24.0.1 My ram had another failure and Ubuntu 22.04 entered into a state where I could not install or uninstall any thing. I did different things to repair this. I had no luck in fixing this. I decided to get thundebird Email working and I hit a suprise. I do not get a visible Thunderbird icon when I installed thunderbird. It also seems to be already installed (In installed the optional ëxtras¨when I installed Ubuntu). I had to fix the desktop icon by commenting out NoDisplay=true in a copy of the file thunderbird.desktop that I moved to ~/local/share/applications. I wonder if this is partly due to this being the type of application that would be supported by the subscription service.
