clamav (Ubuntu)

Bug Description

Binary package hint: clamav

apparmor's usr.sbin.clamd file has an incomplete setting to allow clamd to run.

In /etc/apparmor.d/usr.sbin.clamd

...add this line: capability dac_override,

/usr/sbin/clamd {
  #include <abstractions/base>
  #include <abstractions/nameservice>

Then do:

sudo /etc/init.d/apparmor reload
sudo /etc/init.d/clamav-daemon start

This is only needed if the default configuration is modified to run clam with the root user. This may be required in certain situations where the AllowSupplementaryGroups option is needed.

We should add the dac_override capability to the apparmor profile.

I suspect that the problem is still there.
The fix has been released, but the same error message is still there.

I have a freshy installed clamav-daemon
sudo apt-get install clamav-daemon

Look what I have got:

anatoly@NLANGo:~$ clamd
ERROR: Can't open /var/log/clamav/clamav.log in append mode (check permissions!).
ERROR: Can't initialize the internal logger
anatoly@NLANGo:~$ sudo clamd
[sudo] password for anatoly:
ERROR: initgroups() failed.
anatoly@NLANGo:~$ clamd -V
ClamAV 0.95.3/11104/Sun May 30 14:38:16 2010

I am running Ubuntu 9.10, i386
I will try to add some additional information to this bug report using apport-collect command on my computer.

Architecture: i386

What happens if you do:

sudo /etc/init.d/clamav-daemon start

here is a reply to your question:

anatoly@NLANGo:~$ sudo /etc/init.d/clamav-daemon start
[sudo] password for anatoly:
 * Starting ClamAV daemon clamd /usr/sbin/clamd already running.

Not a bug then. Thats the correct way to start clamd. If you want something a user can run, see clamdscan or clamscan.

I am getting the same problem 'After upgrade, clamav's clamd gives "ERROR: initgroups() failed."' upgrading to clamav 0.96.5+dfsg-1ubuntu1.10.10.2. This is the latest version using apt-get. The recommended fix is in place in /etc/apparmor.d/usr.sbin.clamd.

corp-postfix:~$ sudo /usr/sbin/clamd VERSION
ERROR: initgroups() failed.

Thank you.
