Signatures won't update manually

Ubuntu 18.04 with ClamTK installed from repos.

No signatures upon opening so I initiated manual download.

In .clamtk/db, a tmp folder appears and file grows to 50 Mb in size, then the tmp folder is deleted and it starts over again. I tried installing version 6.02. Same.

I can manually download the daily.cvd from https://database.clamav.net/daily.cvd in Firefox.

Log file is below:

Is this a server-side issue?

Thanks,

jake
