Univention Nextcloud Errors:
RuntimeException The antivirus executable could not be found at /usr/bin/ or The antivirus executable could not be found at /usr/bin/clamscan
Log in to the Univention server shell and run sudo -i to access as root. Then run univention-app shell nextcloud to gain shell access to the Nextcloud container.
Look in /usr/bin to make sure that there is a clamscan directory with the executables inside.
cd /usr/bin
ls clam*
If it does not exist, clam AV is likely not installed.
Install ClamAV
apt-get install clamav && apt-get install clamav-daemon
This will install ClamAV and the daemon/service, afterward check again:
cd /usr/bin
ls clam*
You should now see several directories that match.
Run the freshclam command to install and update the database.
Run a scan to make sure that the ClamAV is working properly:
clamscan / -r
Go back and save your AV security settings, you should no longer receive an error.
