Thnx for the upgrade commands.
Furtheon, i saw that some of the log files are not readable. Mail.log, messages, en the clamav logs. I found that the problem lies within the rights. Bij editing the clamav logrotate.d files, and creating 2 logrotate files for mail.log and messages, we can override the standard value, and make sure they are readable.
Do you think this is a good solution? or anybody has a better way?
