Unfortunately, I couldn't find the file /var/log/installer/debug, the only file with the same folder was /var/log/installer/dm.
Also, it seems apport-collect 567899 did not work correctly. I ran it and it opened a web page where I could put my e-mail and password of OpenID, but the button "Continue" wasn't a link (it looked like normal text). Moving the cursor to the text "Continue" and pressing Enter did nothing.
Attaching /var/log/syslog as requested.
