@liborukropec Thanks for helping!!
That worked but only for the version pointed to by the soft links. I had MCUXpresso 11.2.0 and 11.4.0. Since I installed 11.4.0 after 11.2.0, then the mcuxpresso links were pointing to it and it was the only option showing with dpkg -l. So now I have a stray MCUXpresso installation that I don't know how to remove. But I think it is just a matter of removing the folder now that dpkg -r got rid of the installed version.
