Ubuntu 11.04 install fails

[bigoperm]

Binary package hint: ubiquity

Installation failure when I'm using USB or cdrom (in the case of the attached log files, it was a CD attempt). I have verified that the ISO, and the CD, are not corrupt: the ISO passes the md5 checksum, and the CD passes its internal self-check.

During installation, there are packages that (apparently) need to be removed toward the end of installation -- this is where the installer is crashing.

hi bigoperm,

Does the installer give you an error message, or just hang there doing nothing?

If there's an error message, could you post it here? there's a log file for the installer in /var/log/installer/debug (or in /var/log/ if the install didn't complete).

Let's see if these files give us a clue as to what's going on.

Thanks!
