installed two versions of dolphin emulator now neither works.
 

I cant uninstall dolphin emulator master or regular nor use them. How can i fix this besides reinstalling my whole os?

More specific info required to be able to point you in the right direction.

What distro? How did you install the software?

Used install commands

Sudo apt install Dolphin-emu

It worked

Vulcan wasnt even on there so i loaded: sudo apt-get install dolphin-emu master

Now neither is accesable via command line, or dash and appgrid says nothing to install.

Used sudo apt-get --purge remove dolphin-emu-data-master

Same result. Neither usable and un/re installable

Ubuntu 16.04 is my distro.

Two things I can think of, try
or try running it from the command line, which will often let you know what it is missing.

Edited: Somehow I managed to insert a gap where it shouldn't have been, sorry. :)

Neither of these methods work.

Tuens out i had the package installer set to gdebi. Swapping it, and that command you suggested of deleting seams to have fixed it. Thanks

Kinda embaressing, missed the - in dolphin-emu
