Open the terminal from Applications menu -> Accessories -> Terminal run the following commands

Then reboot your system.

    My first 15 minutes of experience with any linux was a networkmanager crash. it took me several hours of trying to cope with it myself (I thought that I’m doing something wrong), yet it seems that after n-teen years of development Linux still fails at simple tasks.
    Thankfully it’s not my computer I set up linux on.

    Anyways, back to the topic: neither the commands worked, nor the manual operation (the file cannot be edited or deleted, despite I made my account member of all possible groups). What’s up with that? I should have typed some more magic, maybe?
    Eventually I’ve solved an issue by killing the process (Knetworkmanager, like if that K was necessary?) and suspending to disk. Hopefully one of the fixes that are currently being downloaded solves the issue. I just hope for it.

    @mctom: the “more magic” is “sudo” before each command -

    sudo service network-manager stop
    … etc.

    “sudo” runs the command as the root user, which is not the same (has more powers) even than making your user a member of all admin groups.

    Maybe the OP is running always as root (!!!! gasp!) and didn’t think of sudo because of that.
