can not update Clamav virus database

I saw Clamav virus database updating warning in the log file. So I tried to update the virus database manually:

Code: Select all

[root@ ~]# sudo freshclam
ERROR: Can't create temporary directory /var/lib/clamav/clamav-9cf77befbabaa420357e9f96c9845c29.tmp
Hint: The database directory must be writable for UID 1001 or GID 1001
It seems that some file/directory permission error occurred.

How to solve this ?

Thank you.

Try chmod 775 clamav directory.

I tried your suggestion, it did not work:

Code: Select all

[root@ ~]# chmod 775 /var/lib/clamav/
[root@ ~]# sudo freshclam
ERROR: Can't create temporary directory /var/lib/clamav/clamav-b66cc590377020bed528d61f99a29b2e.tmp
Hint: The database directory must be writable for UID 1001 or GID 1001
But your idea inspired me. I changed permission to 777, then the virus database can be updated. After updating finished, I changed the permission back to 755.

Is this a safe way?

Thank you.

I checked that directory, the owner is :

Code: Select all

[root@ lib]# ls clam* -dl
drwxr-xr-x 2 775 clamupdate 4096 Mar 16 08:06 clamav
According to former warning message, it should be "writable for UID 1001 or GID 1001". But I don't know how to change the owner to UID 1001 or GID 1001.

Maybe if I change the owner to correct one, then Clamav will be updated automatically.
