remove software from /opt

Question

The software installed in that folder is not shown in Ubuntu Software Center in installed section. So I cannot remove it from GUI. How can I do it with terminal? How do I get the exact name of the package to be removed?

Solution

the software was not part of debian package. So the solution was to run the uninstall file in that folder:

sudo ./uninstall

How did you install that software?

[N0rbert]

Please add output of dpkg -S /opt to the question.

That could leave artifacts. An uninstall procedure should be preferred if present.

@Rinzwind The problem is that I am yet to find an uninstall procedure that works better with applications based inside the opt folder. If you find one please post it.

[Rinzwind]

Oh you are misunderstanding: the uninstall should in the /opt/ directory of that software. Example: /opt/jasperreports-server-cp-5.1/ has a uninstall. The bigger installation all have one ;)

Not all of them. I just checked chrome and it don't have an uninstall file. I also looked for this when I uninstalled Genymotion.

[Rinzwind]

Genymotion you start by running a binairy, it does not install. And the "help" claims there is a --uninstall option (ie. `./genymotion-{version}.bin --uninstall). Chrome will be a sandboxed install.

That method doesn't work anymore for unknown reasons. Believe me I tried.
