Attilio's questions

I have caps-lock key remapped to control, which usually works fine, but after some uptime and one/more suspend/awake cycles* this mapping breaks, and caps-lock reverts back to the default behavior -- i.e. turning on the led and capitalizing whatever I type. (Even though the Tweaks UI still shows it as being mapped to Ctrl -- see picture below.)

Questions:

• Is this a known issue (with maybe a known fix)? (Could not find anything relevant with a quick search.)
• Is there a way to debug the problem, preferably from the command line?

*Remark: I'm not sure it is the suspend/awake cycle that causes the problem, but I can't connect it to anything else...

Remark2: removing and readding the mapping (or rebooting) solves the problem, but it would be nice to find a more permanent solution.

I am getting the following error while trying to manually run freshclam on Ubuntu 18.04, as super user (I already stopped the daemon as described in other questions).

# sudo freshclam

Manually creating the file works though, so I'm not sure this is a permission issue.

I found the two sources below:

https://www.linuxquestions.org/questions/debian-26/warning-can%27t-download-main-cvd-from-db-local-clamav-net-786955/

But what they were suggesting did not help either (I don't have quotas, and I tried stopping AppArmor, but still the same issue.)

Any other ideas, what I should check?
