Some bug reports are coming to my mail reporting issues concerning install on hard drive not possible.
This is a bug due to ubiquity, the only way untill next release to fix it is to run this command from terminal:
sudo apt-get remove ubiquity
sudo apt-get install ubiquity
also it seems that the whole logging tree menu is useless, might be due to the last cleanup session i ve did for get the iso < 4gb, removing all gtk traces might have removed some apps, i ll investigate
Please, keep using the bugtracker instead of mail me for report bugs, that will be far more efficient.
