Can't run sudo -u wwwrun

[Owlsun]

Hi

After last slowroll update I must to run nexctcloud’s occ command as wwwrun user with the following syntax sudo -u wwwrun php occ.
But the system prompts for wwwrun passwort which I don’t know and as far as I understand doesn’t exist at all because wwwrun is a system user.

sudo -u wwwrun php occ
[sudo] password for wwwrun:

What is a correct way to run occ command?

[Owlsun]

su wwwrun
Password: 
su: Authentication failure

No luck with runuser as well…

sudo runuser -l wwwrun -c 'php occ maintenance:repair --include-expensive'
This account is currently not available.

Logging in as user wwwrun

Hi, the su way doesn’t function because wwwrun is not allowed to login on any ways. But the sudo way should do it: su - sudo -u wwwrun -s first you have to become root and ten sudo to wwwrun with a shell hope this helps

OK…
Finally I got it.

I have realized that while hardening my Nextcloud server I disabled root login
After changing the following lines in /etc/passwd
root:x:0:0:root:/root:/sbin/nologin
to
root:x:0:0:root:/root:/bin/bash
and
wwwrun:x:470:470:WWW daemon apache:/var/lib/wwwrun:/usr/sbin/nologin
to
wwwrun:x:470:470:WWW daemon apache:/var/lib/wwwrun:/bin/bash

I have been able to run runuser -l wwwrun as well as su - which

On the second thought, there is no need to allow root login as long as one use runuser -l wwwrun.
It is enough to temporary allow login for wwwrun user in /etc/passwd

wwwrun:x:470:470:WWW daemon apache:/var/lib/wwwrun:/bin/bash
