Bug#1104536: ftpstats references wrong file in logrotate config

[Justin Pasher]

Package: proftpd-core
Version: 1.3.8+dfsg-4+deb12u4

The logrotate config for ProFTPd (/etc/logrotate.d/proftpd-core) runs 
ftpstats as part of the postrotate command when rotating 
/var/log/proftpd/xferlog. However, the call references the file 
/var/log/proftpd/xferlog.0. The default config in Debian starts naming 
rotated log files with .1, not .0, so the command never runs successfully.

Instead, the call to ftpstats should reference the newly rotated file: 
/var/log/proftpd/xferlog.1
