ClamAV: clamd.ctl file is not getting created on ubuntu

Question

I have ubuntu 16.04.6 version and I'm trying to install & run the clamdscan on it to check for antiviruses.

I've used the installation instructions as given in their website. ie.

sudo apt-get install clamav
sudo apt-get install clamav-daemon

The above 2 commands works fine. But when I try to download the definitions (which I'm assuming is mandatory after the above) by running the command

sudo freshclam

it fails throwing the following error:

^Clamd was NOT notified: Can't connect to clamd through /var/run/clamav/clamd.ctl: No such file or directory

According to this accepted answer, the file should get created after installing clamav-daemon but obviously that does not happen.

I faced this issue on my Ubuntu 20.04 LTS machine,

What I did was:

run sudo systemctl stop clamav-daemon.service
then run sudo rm /var/log/clamav/freshclam.log (sometimes it gets locked)
start the service sudo systemctl start clamav-daemon.service

to ensure everything is OK run sudo systemctl status clamav-daemon.service and the output should look something like this:

➜  ~ sudo systemctl status clamav-daemon.service
● clamav-daemon.service - Clam AntiVirus userspace daemon
     Loaded: loaded (/lib/systemd/system/clamav-daemon.service; enabled; vendor preset: enabled)

May 03 05:03:51 user systemd[1]: Starting Clam AntiVirus userspace daemon...
May 03 05:03:51 user systemd[1]: Started Clam AntiVirus userspace daemon.

Now run sudo freshclam and check the log file (or console output)

Enjoy!

I found that after you run the:

freshclam

And get this error:

Clamd was NOT notified: Can't connect to clamd through /var/run/clamav/clamd.ctl: No such file or directory

You just need to run restart for the demon:

service clamav-daemon restart

And then freshclam again and all works.

Add a sock file for ClamAV:

sudo touch /var/lib/clamav/clamd.sock
sudo chown clamav:clamav /var/lib/clamav/clamd.sock

Then, edit /etc/clamav/clamd.conf - uncomment this line:

LocalSocket /var/lib/clamav/clamd.sock

Save the file and restart clamav-daemon.service

Another error:

sudo freshclam

Add a sock file for ClamAV:

sudo chown clamav:clamav /run/clamav/clamd.sock

sudo systemctl restart clamav-daemon.service
sudo freshclam

That's it.

Is there no better way to do this while running provision script on a server ? I mean, locally it could work. But i'm trying to run provision scripts to execute commands on AWS EC2 instance and opening and uncommenting a file on the fly in the server seems weird. — Nikhil Nanjappa, Sep 24 '19 at 11:08
just type `nano /etc/clamav/clamd.conf` uncomment and save. This tutorial fixed an issue on my system. — JoKeR, Sep 26 '19 at 08:17
if you still get another error `/var/run/clamav/clamd.ctl` no such file or directory create and give ownership to a sock file in that directory as well as specified in my answer. — JoKeR, Sep 26 '19 at 08:49
