I've typed in cd Downloads. Says no such folder. I'll try it the way you listed it.
Whatever is causing that is probably the whole problem.
I simply must have something on my system that makes Ubuntu run weird.
I either get no such folder, or you don't have permission.
I don't have the opt folder anywhere and can't create it. I've opened and looked through every folder listed and don't see it. I got the path Sys>users>local from a few answers. OPT ain't in that folder.
Or how to create the damn folder? Full path please.
@palmtree - I get as far as using the opt folder, terminal says it doesn't exist (it doesn't) goodbye and stops.
It's funny - the TAR.BZ2 for the older FX ESR which updated wrong worked.
I extracted to the downloads, clicked on the FX icon and it ran, albeit the wrong version.
I got the files for Skype and the Epson Photo V300 to work via terminal. FX ESR worked on Mint and 10.10 just the way you described.
BTW, what's the number sign mean? Enter? I've used>
