Hello Michel, thank you for taking the time to file this bug report and help us make Ubuntu better!
The failure seems to be actually in apache, not apr: Paramétrage de apache2-mpm-prefork (2.2.14-5ubuntu8.4) ... * Starting web server apache2 apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs It would appear that apache failed to start on installation. Do you have another web server already running on your system on port 80? If so, you will need to stop that webserver and then finish the installation with: sudo dpkg --configure -a This is not a bug, but a temporary failure due to the system state.
