I have the same problem, it won't start on ubuntu 18.04 even with the renamed files.
Is there anything I can try ?
Viewing post in Has trouble starting on Ubuntu 18.04
Is there any error message you could give me so I can help you better?
Also, in version 2.2.0, the files are already renamed, so you shouldnt have had to do anything.
EDIT: You could also jump in the discord to make debugging this faster. (https://discord.gg/88UPmxh)
