Después de la actualización de la distribución de Linux, Moin bajo WSGI lanza 500 errores

tengo un MoinMoin instancia instalada en /opt/mydebianwiki; el wiki se ejecuta bajo [wsgi] / [apache2]. Recientemente actualicé de Debian Linux 6 (squeeze) a Debian 7 (wheezy); antes de la actualización, mi MoinMoin La instancia funcionó bien.

Sin embargo, después de actualizar a wheezy, comencé a recibir errores de http 500 cuando intentaba acceder al sitio.

Google me lleva a esto hilo de usuarios moin , que decía que solo podía correr su -c "moin --config-dir=/opt/mydebianwiki maint cleancache" www-data para solucionar el problema; sin embargo, eso tampoco tuvo éxito (ver errores al final de la pregunta).

¿Como puedo resolver este problema?

Make sure the directory and the subdirectory "pages" are owned by the web

It is recommended to use absolute paths and not relative paths. Check
also the spelling of the directory name.

El problema es que mi configuración moin local en /opt/mydebianwiki/wikiconfig.py no se encontró, aunque especifiqué ese directorio en mi moin ... maint cleancache mando. Parece que el directorio por defecto de Debian ( /etc/moin ) estaba tomando prioridad cuando corrí su -c "moin --config-dir=/opt/mydebianwiki maint cleancache" www-data.

Mi solución, fue renombrar temporalmente /etc/moin y ejecute el comando. Esto solucionó el problema:

root@tsunami:/opt/mydebianwiki# mv /etc/moin/ /etc/antimoin

root@tsunami:/opt/mydebianwiki# su -c "moin --config-dir=/opt/mydebianwiki maint 
 cleancache" www-data
