[clamav-users] /bin/mkdir: cannot create directory ‘/run/clamav’: File exists

Hi Kris thanks for trying to help,

Here you go:

dpkg -L clamav-daemon |grep system

/lib/systemd
/lib/systemd/system
/lib/systemd/system/clamav-daemon.service

cat /lib/systemd/system/clamav-daemon.service

The chown and mkdir look a bit suspect to me;  I'm not seeing anything like that in the Debian packages (which should be mostly the same in Ubuntu).  What I *do* see in one of the stock files
(/lib/systemd/system/clamav-daemon.socket) is this stanza:

[Socket]
ListenStream=/run/clamav/clamd.ctl
#ListenStream=127.0.0.1:1024
SocketUser=clamav
SocketGroup=clamav
RemoveOnStop=True

which if I understand correctly, implies that clamd on this system is using systemd's socket creation/handling voodoo rather than doing so itself.

Can you post:

- Output from  "dpkg -L clamav-daemon |grep system"

- Contents of any .service or .socket files from the above list

- Contents of any files in /etc/systemd/system/clamav-daemon.service.d

This seems to indicate that you're not using the stock systemd service definitions from Ubuntu/Debian upstream.
