Thank you for your support :blush:

Got it fixed by editing the users sudo rights, which should be like the one of user pi on an standard installation.


Hi, could you provide details of the fix.
I’m running into the sam error and don’t know how exactly you edited the sudo rights.

Thank you :slight_smile:

The problem was, that i didn’t used the user pi.
To use another user, you have to do the following:

But be careful by editing the sudo files, as an error could result in sudo not properly working.


Type in your user instead of username:


touch /etc/sudoers.d/username

chmod 0440 /etc/sudoers.d/username

nano /etc/sudoers.d/username

Edit the file: /etc/sudoers.d/username with the following:


touch /etc/sudoers.d/username, the name of the file isn’t allowed to contain a . aswell as a ~
