Right now, this looks like an X-Y problem. If the actual goal ("X") is "make my Epson Inkjet printer work", then telling us the printer's model number would be far better. I probably won't be the person to help, but there are others here who know printers. > I installed gdebi and tried to install the above with gdebi. FYI, gdebi is obsolete. You can do it with apt or apt-get now. You just have to remember to prefix the filename with ./ or ../ or use an absolute path to it. apt-get install ./foo_bar_arch.deb > The gdebi GUI says: > > Error: Dependency is not satisfiable: lsb (>=3.2) > > What should I do? That package no longer exists; the last Debian release to have it was jessie. Using an obsolete driver .deb package (from 2012, if that version string begins with a year) might not be the best choice. I would try something different, either more Google research, or waiting for someone like Brian to chime in. But definitely tell us what the printer is.
