Since ubuntu 19.10 I can't find gmusicrowser in the repositories.
After installing gmusicbrowser_1.1.15_all.deb there is following error showing up in the terminal.
Can't redeclare "my" in "my" at /usr/bin/../share/gmusicbrowser/gmusicbrowser_list.pm line 8001, near ",my"
Compilation failed in require at /usr/bin/gmusicbrowser line 440.
BEGIN failed--compilation aborted at /usr/bin/gmusicbrowser line 473.
I know this is an older thread, I just wanted to post the solution in case anyone finds this thread in a search.
