Hi,

For tha manual refresh as you show it to work the service needs to stop anyway.
Did you do that and why (probably as part of the debugging)?
I stopped my service as well and removed the databases.
I see it doing the download (fast in my case at first):

You could also try --verbose and --debug if anything special happens before
your timeouts (some locking or hang).
Now let me slow it down to recreate your case to be above 30 seconds.
root@b:~# tc qdisc show dev eth0
qdisc noqueue 0: root refcnt 2
root@b:~# tc qdisc add dev eth0 root handle 1: htb default 12
root@b:~# tc class add dev eth0 parent 1:1 classid 1:12 htb rate 14kbps ceil
14kbps
root@b:~# tc qdisc add dev eth0 parent 1:12 netem delay 250ms
root@b:~# tc qdisc show dev eth0
qdisc htb 1: root refcnt 2 r2q 10 default 18 direct_packets_stat 0 direct_qlen
1000
qdisc netem 8001: parent 1:12 limit 1000 delay 250.0ms
Now I was able to reproduce your case:
<
* Operation timed out after 30000 milliseconds with 19618356 out of 59605116
bytes received
* stopped the pause stream!
* Closing connection 0s [=========> ] 18.71MiB/56.84MiB
This is the 30 second timeout that is the default.
Per [1] I was setting the timeout to a higher value in
/etc/clamav/freshclam.conf
ConnectTimeout 300
ReceiveTimeout 300
And then it worked again.

This is a local config issue when matched with a very slow internet connection.
The defaults are from upstream, so a discussion about bumping them for higher
defaults would have to be there. But I think you are good just adapting your
system as needed.
I found that a discussion about that default already happened and the default
was set to 0 (no timeout) on the receive [2].
That change is rather new and we will pick it up naturally with the newer
version.
But it is good to be aware as we will also have to change
debian/clamav-freshclam.postinst.in
Which sets the old default of 30 still
205 [ -z "$ConnectTimeout" ] && ConnectTimeout=30
...
227 ConnectTimeout $ConnectTimeout
For now just change your local config.
But we should try to fix that before 20.04 is released in that new version
(can't really wait on a new clamav). But we'd have to check if there are
negative interactions first.
