I have some custom Nvidia + Cuda drivers installed. I made bad experiences with installing updates under Ubuntu. Several times it broke my system already since the new updates were conflicting with customly installed software. This was especially bad when Ubuntu tried to install / update its own version of the Nvidia drivers while destroying my manually installed ones (Nvida + Cuda 6.5)
Since I don't want to have that experience again: Is there any command of the form
sudo apt-get install update for thunderbird only
Such that it only updates that one program and doesn't effect all the others (just like updating works on Windows).
I googled around and I know that similar questions have been posed, but either the answers don't work or they again recommend installing all security updates etc.
