I have installed clamav and I want to to update the files that it uses to identify viruses:
$ sudo freshclam
ERROR: /var/log/clamav/freshclam.log is locked by another process
ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log).What should I do with this error?
EDIT:
$ sudo lsof /var/log/clamav/freshclam.log
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
freshclam 866 clamav 3wW REG 259,1 100134 10486045 /var/log/clamav/freshclam.log4 Answers
Short answer:
You don't have to run it manually because it has been run automatically and is running in the background, that's why you receive that message.
If you want to stop the daemon and run it manually:
sudo systemctl stop clamav-freshclam.servicerun it manually:
sudo freshclamWhat is happening and how to handle it?
Every time when you encounter into a similar situations, errors like file x has been locked or Another process is using this file : /path/to/x you can use the lsof command to find out which process is using that file, in your case if you run:
sudo lsof /var/log/clamav/freshclam.logYou should get an output like:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
abc 126 user 3wW REG 259,1 100 1048 /var/log/clamav/freshclam.logThe abc is the name of process which is using that file, in your case it's: freshclam.
That means freshclam which you want to run has been already ran by clamav daemons.
you can use less /var/log/clamav/freshclam.log or similar commands to see what's going on.
So you don't have to run it manually anymore, it's a process to avoid any conflict and having multiple instance of a same process doing same thing at the same time.
If you want to make it stop and run it manually, then send a SIGTERM to its process, that gives the process a chance to finish its job and close itself cleanly, something like:
sudo pkill -15 -x freshclam- in this case
sudomay be necessary. - 15: SIGTERM is the default
Then run it manually:
sudo freshclamHowever in this case you can use:
sudo systemctl stop clamav-freshclam.serviceto stop the daemon.
4sudo /etc/init.d/clamav-freshclam stop
sudo freshclam
sudo /etc/init.d/clamav-freshclam startThis might be another option for this...
sudo service clamav-freshclam stop
sudo freshclam
sudo service clamav-freshclam startHope this helps...
1Maybe this is the most simple answer to the question:
sudo su clamav freshclam
Obviously, freshclam is already running with the clamav user (as sudo lsof /var/log/clamav/freshclam.log tells us). Call it again in this user's name to wake it up and update the database. Then to check the success...
sudo less /var/log/clamav/freshclam.log
