Additional context

Looking at the error message, it seems that the string "USER" in the path should be the username. That path does indeed not exist.

[rptb1]

That path does indeed not exist.

But it doesn't exist in the user directory either.

(deck@plover ~)$ ls .var/app/com.usebottles.bottles/data/bottles/templates/

Also, I'm able to create "Application" and "Custom" (with defaults) bottles.
