Cant open config file mupen64plus.cfg when updating

[Weenyhead]

Hello, I have a pi 3 that I am running retropie 4.1 on berryboot. I am running into the problem: mupen64plus cannot save (both ingame and save state)

The fix: @BuZz said in mupen64plus cannot save (both ingame and save state):

update retropie-setup and update mupen64plus from binary (or just choose update all installed packages). This was fixed recently.

This did not work for me. I'm guessing my problem is that it can't open the mupen64plus.cfg config file. When I try to update mupen64plus I get

...

I am able to see the file and read and write to it from the command line.

pi@retropie:~/RetroPie-Setup/logs $ ls -la /opt/retropie/configs/n64/mupen64plus.cfg
-rw-r--r-- 1 pi pi 15499 Jan 11 11:25 /opt/retropie/configs/n64/mupen64plus.cfg

I chmod 777'd it and still getting the same error.

Thanks in advance for any help.
