New user cannot create files in its home directory

Question

I created a new user golden in linux by running adduser command.

After that I am trying to generate ssh keys for that new user and every time I am getting permission denied error:

golden@machineA:~$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/golden/.ssh/id_rsa):
Could not create directory '/home/golden/.ssh': Permission denied

Any thoughts what is wrong?

Update:

golden@machineA:~$ pwd
/home/golden
golden@machineA:~$ ls -l
total 0
golden@machineA:~$ ls -lrth
total 0
golden@machineA:~$ ls -lrtha
total 20K
-rw-r--r-- 1 10001 10001  675 May 10 11:54 .profile

drwxr-xr-x 8 root  root  4.0K May 10 15:44 ..

Update2:

golden@machineA:~$ ls -ld /home/golden
drwxr-xr-x 2 10001 10001 4096 May 10 11:54 /home/golden
golden@machineA:~$ id golden
uid=1001(golden) gid=1002(golden) groups=1002(golden)

Answer 1

The owner of /home/golden is user 10001, not user golden. Normally, when you create an account, this creates a home directory for the user, and that home directory would of course belong to the user.

The reason this didn't happen here is probably that /home/golden already existed. Depending on the options you passed to adduser, it may or may not have told you about this. The reason /home/golden existed is presumably because there used to be an account called golden with the user id 10001, then this account was removed without deleting the home directory. Now there is a user account called golden again, but with a different user ID.

Assuming that this is what happened, and user 10001 no longer exists, you can change the ownership of /home/golden to the new account. Of course this allows the new user to see the files that the old user left behind, but in your case there are no interesting files anyway.

sudo chown -R golden:golden /home/golden

If you delete an account, you should either remove its home directory (deluser --remove-home) or rename it (mv /home/golden /home/golden.1001.archived).
