Ok. I know there are other posts about uninstalling Thunderbird, but my problem is weird. First when try and find Thunderbird in the Software Center to uninstall it it does not show up as installed, but only in the list of available to install. YET I do have it and MANY other Thunderbird files and folders when I do a search in the File System:

Ok, so I did the old "sudo apt-get remove --purge thunderbird -y" and I got this back:

It looks to me that it DIDN'T remove Thunderbird etc. and when I searched "File System" I got the same result as above!

My question is, why is this weirdness happening, and can I manually grab all of those "Thunderbird" Files and Folders and manually trash them safely? Are there any "Thunderbird" files that might cause problems in any way if I trash them?

Ok, I tried using gksu nautilus and got an error message:

enter image description here

What does this mean? Be kind, I'm a novice!

Ok, I tried gksu nautilus again and got this warning:

No, you can safely delete the folders. However, folders with a lock on them can't be deleted by moving to trash.

Fire up a terminal, and enter the following to become root:

sudo nautilus

and then repeat your search and delete the thunderbird files.


Prior to 13.04 , try gksu instead of sudo.

  • Oh yeah, sorry I'm using Ubuntu 12.04 on a USB on a HP Pavillion Laptop. Should I then use gksu ? I've used sudo for other things with no problems.

  • Use gksu to be on the safe side. If it works, mark the answer correct. May 15, 2013 at 22:19
  • Ok, I'm a frightened noobie to Linux so when I get a message like this after typing in a command in the terminal I get a bit freaked:

  • just relax and only delete thunderbird files, youll be fine May 16, 2013 at 3:44
  • Ok, but answer my update to my question first. What does it mean about the folder (see above) and what is the command? gksu nautilus ? If so I get that message above. Should I use sudo afterall?
