I installed TrueCrypt from their website (.tar.gz file) extracted through the archive manager to
/usr/share/truecrypt. I no longer need the app but I cannot uninstall it through
sudo apt-get remove
I get an error message:
'virtual packages like truecrypt cannot be removed'.
All of the sub-directories and files in
/usr/share/truecrypt have a padlock symbol on them.
I don't know how to remove unwanted apps beyond these basics, I'm hoping you can help. I have a small(memory), elderly Toshiba Satelite laptop so it doesn't need to carry any baggage.
