I don’t have Internet, and I use Internet through a USB modem device which is supported in only Windows, so I tried to install Wine to run that software, and I downloaded Wine but it says
dependency is not satisfiable: libgettextpo0
What to do?
While this may not be the only dependency you will need, you can find the libgettextpo0 from here. Double click on the file in Ubuntu and click install. You need to do this before you install wine.
On this page you can also search for packages so if you see you have more dependencies you might have to go back to this page. Type the name of the dependency in the search box, download it and repeat.
