I am using a Debian 9 server.
Usually I access via
ssh to a normal user (say
root, because I disabled
Lately I was setting up a git-server where I created a user
git with the group
git and restricted him to
Playing around a little while I added
user1 to the group
git like this:
usermod -aG git user1
This worked alright,
user1 was member of the groups
At the end I wanted to undo this, so I used:
usermod -G user1 user1
Shortly after this, I lost my internet connection and had to reconnect. I can
user1 alright, but when using
su to access
root, there is an error:
user1@hostname:~$ su Password: Cannot execute git: No such file or directory user1@hostname:~$
I included the information about
git-shell, because I have no idea what else could be the reason. Hopefully it is not all lost and somebody can help me to regain control.
PS: There isn't any other root-like user, so
sudo isn't working, since
user1 "is not in the sudoers file".
PPS: I could reset the
root password via VPS-login, but I am not quite sure whether this is going to work or make everything worse.
