entire fs is nobody-nogroup - can't sudo

[pastic (A Parrot)]

Briefly describe your issue below:
I just installed (from Etchered USB-stick, standard installer with the blue/red DOS-like interface) Parrot Security 4.6 KDE, quadraplebooting with Mint 19, KDE neon and Win 7. My problem is that I cann’t run any sudo commands even though my only user has sudo privileges. I cannot even run dmesg, I get permission denied. I noticed that the entire filesystem execpt home is nobody/nogroup rather than root/root and I suspect that is the source of my problem. Are these permissions intended or did something go wrong during install?

Should I just boot another OS and change the filesystem ownerships, or will that mess up Parrot?

What in the world happened to this fs permissions are all wrong and the old and new kernels point to the same thing. You’re probably trying to boot too many operating systems and this is confusing the machine.

I’ve had the same issue. I really like to use Parrot KDE home but I couldn’t get the home edition installed. The Home edition of the parrot installer doesn’t install GRUB properly for me and the workarounds weren’t really working for me.

It seems the KDE editions of both Home and Sec have lots of big issues. the ‘nobody-nogroup’ bug happened to me on a dedicated install of the KDE Security Edition. (I’d really rather be using home, but see above) My guess is the MATE versions are the main focus, which is fine, It’s a pentesting OS at heart after all.

Yes, could have been KDE that is spooking. Thanks for the tip!
I have now installed MATE and it works much better.
Only thing now is that the system clock is off by two hours, correct time zone is set and it is supposed to check internet time, but it is still off by two hours. I will have to look into that.
