I installed and configured pure-ftpd to transfer some files. As I only
needs this a few times a year, I removed it again.

On purpose, I did not purge, as I want to use the configuration next
time on install again.

Now logrotate fails:

The fix is simple:
On removal, use one of the "taboo" extensions of logrotate and on
reinstall remove this extension again. See logrotate(1) for details.
