I still use synaptic to manage packages because of its simplicity and zulucrypt packages you most likely have installed are those highlighted in the below image:
https://imgur.com/a/jFezM I also suggest you use synaptic because doing stuff on the terminal is not very user friendly. 1. Install synaptic with command: sudo apt-get install synaptic 2. Temporarily allow GUI programs to run privileged with command: xhost +local: 3. Run synaptic with command: sudo synaptic 4. Search for package "zuluCrypt" 5. Remove all installed packages you see. Installed packages will be green highlighted. In any of the above commands,if you get a "could not acquire lock error", keep trying to run the command on 2 seconds interval until it succeeds. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xrandr in Ubuntu. https://bugs.launchpad.net/bugs/1722615 Title: zuluCrypt doesn't launch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xrandr/+bug/1722615/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
