[clamav-users] Freshclam not working on freshly build source 0.102.1 on Debian 10

[Micah Snyder (micasnyd)]

Hello!

This issue is a two-parter...

Our Cloudflare CDN ("mirror" infrastructure) seems to be distributing stale files for up to a few hours after new versions of daily.cvd are uploaded, despite our best efforts to clear the cache.  The issue doesn't affect incremental / cdiff updates, but for full CVD downloads - freshclam freaks out about the version being out-of-sync. 

We'll be addressing the issue by making freshclam more lenient when the version is off-by-one.  This coming soon in patch release 0.102.2.

For more details, please take a look at https://bugzilla.clamav.net/show_bug.cgi?id=12451 

Regards,
Micah

    Discovered that running freshclam with the '--no-dns' option works.
    Is this a problem with my dns resolver or a freshclam problem?
