As of right now, I create a brand new Google virtual machine. I upgraded the OS from Debian 9 (Jessie) to Debian 10 (Buster). For whatever reason, I cannot use superuser. Whenever I try, I get the error:
su: Permission denied. The file permissions for
-rwsr-xr-x 1 root root 63K Jan 10 2019 su
The groups my user (
Lunar) is in, are:
root sudo developers lunar
I also tried doing
sudo adduser lunar wheel, although the group did not exist beforehand, and is not appearing in the groups above. I am SSH-ing into the computer, and I've tried the commands:
su su - su root
Each above the above commands have been executed with and without sudo. Any suggestions?
Edit: After further testing, I cannot su into ANY user, including my own account.
