Nextcloud Snap Cannot connect to “/var/run/clamav/clamd.ctl”: Permission denied (code 13)

[Postyfix]

Hallo liebe Community,

ich habe auf einem Ubuntu 22.04 per SNAP-Installation die Nextcloud installiert.
Jedoch bekomme ich ClamAV nicht korrekt zum laufen.

Fehler:
Cannot connect to “/var/run/clamav/clamd.ctl”: Permission denied (code 13)
stream_socket_client(): Unable to connect to unix:///var/run/clamav/clamd.ctl (Permission denied) at /var/snap/nextcloud/39212/nextcloud/extra-apps/files_antivirus/lib/Scanner/ExternalClam.php#38

Meine /etc/clamav/clamd.conf:
LocalSocket /var/run/clamav/clamd.ctl
FixStaleSocket true
LocalSocketGroup clamav
LocalSocketMode 666
User clamav
…

systemctl status clamav-daemon:

Nextcloud Antiviruseinstellungen sind auf:
Modus: ClamAV-Daemon-Socket
Socket: /var/run/clamav/clamd.ctl

ll /var/run/clamav/clamd.ctl
srw-rw-rw- 1 clamav clamav 0 Jan 5 12:45 /var/run/clamav/clamd.ctl=

Auch diese Anleitung bringt den gleichen Fehler.
Add /{,var/}snap/nextcloud/[0-9]/clamd.ctl w, to /etc/apparmor.d/usr.sbin.clamd like below.
32 /{,var/}run/clamav/clamd.ctl w,
33 /{,var/}snap/nextcloud/[0-9]/clamd.ctl w,
34 /{,var/}run/clamav/clamd.pid w,

then apply it to apparmor:
sudo apparmor_parser -r /etc/apparmor.d/usr.sbin.clamd

edit /etc/clamav/clamd.conf and change it to this (LocalSocket, LocalSocketGroup, User):
…
4 LocalSocket /var/snap/nextcloud/current/clamd.ctl
5 FixStaleSocket true
6 #LocalSocketGroup clamav
7 LocalSocketGroup root
8 LocalSocketMode 666
9 # TemporaryDirectory is not set to its default /tmp here to make overriding
10 # the default with environment variables TMPDIR/TMP/TEMP possible
11 #User clamav
12 User root
13 ScanMail tr
…

restart clamav:
sudo systemctl restart clamav-daemon

sudo mv /var/run/clamav/clamd.ctl /var/snap/nextcloud/current/

Change LocalSocket option of /etc/clamav/clamd.conf and restart clamav-daemon:
LocalSocket /var/snap/nextcloud/current/clamd.ctl
sudo snap restart nextcloud
