Nov 27 10:39:40 server.pemajudigital.com directadmin[410238]: filemanager tree error=request failed, check 'journalctl -u [email protected]' for more information: Post "http://unix/FilemanagerTreeChrootHome": failed to restart userd socket: Unit [email protected] not found. req-uri=/api/filemanager/tree?path=%2F&rooted=true req-user=admin|bisnescow

What could cause this and how do I fix it?
When uploading file via Directadmin file manager, it failed with the above error.

Restarted DA, tried everything I can think of, and nothing worked.

DA version:

This issue is fixed.

The fix:

The reason is due to /etc/systemd/system/[email protected] and /etc/systemd/system/[email protected] are missing. Copied from another working DA server and is fine now.

Why those 2 files are missing is still a mystery.
