Hi there,

I'm trying to upgrade from BackupPC 3 to BackupPC 4 on one Debian system,
but I'm having problems with Apache2 and the BackupPC cgi file.

The web interface tells me "Error: Wrong user: my userid is 33, instead of
108(backuppc)", even if the cgi script belongs to the backuppc user and
suid is enabled:
...
Could you help me to understand where I'm wrong, please?

I think Apache needs permissions to run BackupPC that it doesn't have,
probably because it's running as user 'www-data' and not 'backuppc'.
So you can either change APACHE_RUN_USER and APACHE_RUN_GROUP in
/etc/apache2/envvars from 'www-data' to 'backuppc' and restart Apache,
(which might break everything else that Apache is serving) or if it is
serving other stuff you could install SCGI - which is a bit more work.

I believe this is all in the documentation.
