Omnisharp server installation and execution fail

[drkg4b]

Dear developers,

thanks for the hard work you are doing to maintain this package. I'm having hard times making it work on Ubuntu 18.04 and Emacs 25.2.2. If I give the M-x omnisharp-install-server I always get the error omnisharp--server-installation-path: Symbol’s function definition is void: f-exists-p.

If I download manually the server and use the (setq omnisharp-server-executable-path "<path-to-server-wrapper-script>") I am still unable to start the server on any project mostly due to a Permission denied on the OmniSharp.exe file or if I do a chmod a+x OmniSharp.exe I get a Exec format error error.

I'm not that skilled to debug elisp so I'm turning to you if you could help me figure out what is that I am doing wrong here! Thanks

EDIT:
Being ignorant about elisp is not a valid excuse thus I picked up a guide and was able to debug the issue. Apparently changing f-exists-p to file-exists-p and some other aliases solved the issue for me. I suspect I am having problems with f.el at this point. Anyway after changing a few aliases (I'm not sure there are more) I was able to happily install and run the server.

Hi @drkg4b

Sorry for replying so long after your report. Is this still an issue for you? Which emacs version/platform are you using?
