For some reason I can not create a user for the folder, what could be the reason?

Question

linux

I create the owner user1001:1000 for the /teh/users folder with the command: chown user1001:1000 /teh/users/1001;
Gives an error: chown: invalid user: "user1001:1000"
What could be the problem?

Answer 1

it is necessary to specify either username or uid.
i.e.
chown user:user /path/to/folder
edit.
a. I understand, you have such a direct user, right? user1001 ?
OK. let's try like this.
chown user1001:user1001 /folder/

Answer 2

chown: invalid user: "user1001:1000"
Well, it tells you that the user user1001 is not in the system.
what users are in /etc/passwd?
Maybe they forgot to create the user itself?
