Here's a blog post in French which gives a solution.

In English, you can read this bug report.

To summarise:

1. First you have to add the --verbose option in the script /etc/cron.daily/logrotate to have more information the next time it runs to identify which rotation log cause the problem.

   #!/bin/sh
   
   test -x /usr/sbin/logrotate || exit 0
   /usr/sbin/logrotate --verbose /etc/logrotate.conf`
   

2. Next you have to add the delaycompress option in logrotate configuration.

   Like exemple, I add the nginx's logrotate configiguration in /etc/logrotate.d/nginx:

   /var/log/nginx/*.log {
       daily
       missingok
       rotate 14
       compress
       delaycompress
       notifempty
       create 0640 www-data adm
       sharedscripts
       ...
   }
