We've tried to update Plesk 10.4.4 (Ubuntu 10.04 LTS) to MU39 on several servers via the autoinstaller. We've used the same steps before to update those servers to MU36. On some servers Apache failed to start after this upgrade; libapache2-mod-php5 was removed in addition to the Plesk installation itself. After verifying the logs we found the following: -- The following packages will be REMOVED: apache2-mpm-prefork* libapache2-mod-php5* plesk-core* plesk-l10n* pp-sitebuilder* psa* psa-backup-manager* psa-health-monitor* psa-horde* psa-imp* psa-ingo* psa-kronolith* psa-libxml-proxy* psa-migration-agents* psa-migration-manager* psa-mimp* psa-mnemo* psa-passwd* psa-php5-configurator* psa-turba* psa-updates* psa-vhost* The following NEW packages will be installed: apache2-mpm-worker -- Another server, which had autoupdates enabled, also had the same problems. Anyone here who had the same issues?
