Hi Paul, all: We're triaging this issue now, also reported by a user on Discord.
We issue a zero-byte CDIFF database patch file whenever we want Freshclam to download a whole CVD instead of doing the incremental/patch update. Today we published a zero-byte patch file for both daily and main, as we've migrated about half of the daily signatures over to the main database. Unfortunately it appears we have a bug in 0.102 and 0.103 where Freshclam will complain loudly about the zero-byte CDIFF patch file. I suspect we didn't notice it before because, despite the error message, Freshclam will still do the right thing (at least in 0.102). But it seems 0.103 has a second bug where it will patiently wait until it's at least 2 versions behind before it downloads the whole CVD database. This behavior is supposed to happen when a private mirror doesn't have the latest patch file yet, but wasn't supposed to happen for a zero-byte patch file. So we clearly have 2 bugs to fix ASAP. The good news is, I believe that if we publish 1 more version of daily.cvd and main.cvd, we will see the 0.103 Freshclam clients all download the new daily & main and they'll be good again. I will work with our signature publishing team here to get an update for daily & main out as soon as we're able. I'm sorry about the bug everyone. Thank you for your patience! I will write again a soon as I have an update. -Micah > -----Original Message----- > From: clamav-users <clamav-users-boun...@lists.clamav.net> On Behalf Of > Paul Netpresto via clamav-users > Sent: Wednesday, July 14, 2021 3:30 PM > To: clamav-users@lists.clamav.net > Cc: Paul Netpresto <p...@netpresto.co.uk> > Subject: [clamav-users] Freshclam updates problem > > Hello > > This has started occurring on all our 103.2 systems.
