ClamAV is not updating. Error 503

I am getting regular emails about my readynas' AV being out of date.  I logged on and ran freshclam getting back

 

ClamAV update process started at Wed May 12 11:31:09 2021

Seeing a few other examples I tried

host -t txt current.cvd.clamav.net
current.cvd.clamav.net descriptive text "0.103.2:59:26168:1620826140:1:63:49192:333"

and it wasn't until I ran wget that I got somewhere

I tried from other sources. I don't know if this is something going on in my network or other people are having this problem.  It is resolving and I am not seeing a firewall error. Best I can tell it is something on ClamAV's side and I don't think it is an unsupported version.

 

 

  • Hi @Sandshark,

     

    We are still investigating why the AV database is still not updating for some users even after updating to 6.10.5.

     

    For this particular case, L3 checked /var/lib/clamav and saw that daily.cld was still outdated. L3 needs to renew it so they removed the two files (daily.cld and mirrors.dat) then ran freshclam.

     

    If the user is knowledgeable in Linux, they can try this, but it will be best if they can send the logs to me or @Marc_V so we can forward this to the appropriate team and they can further investigate the issue

     

    Regards,

    Hi Idward,

     

    May I know the model number of your ReadyNAS unit and the current firmware of it?

     

    If the firmware is not yet on 6.10.5, you can try updating the firmware to it. The 6.10.5 firmware addressed an issue wherein the ClamAV fails to update the database. You can read the release notes here.
