I had downloaded arc-theme-solid_1450051815.946cbf5_all.deb file from http://download.opensuse.org/repositories/home:/Horst3180/xUbuntu_15.04/all/ and had installed it using the Software Center but when I decided to uninstall it wasn't showing up in the Software Center. I thought of removing it via the terminal but couldn't think of the correct name of the package to uninstall. This has been the general problem associated with installing any package outside the Software Center. Also, is the name of the package to uninstall the same as that of the .deb file?

Best Answer
You should be able to use
dpkg -I
ordpkg-deb -I
to show information about a package by reading the deb file. Fromman dpkg
e.g.
So in this case, the package name is
arc-theme-solid
