Comment 23 for bug 1066480

Not only the instalation procedure tells that there's no system installed, which is, at minimum, confusing for beginers, but the workarrounds do not work either.
I tried this: http://ubuntuforums.org/showthread.php?t=1205372 which uses the alternate instalation.
The solution was tried and the system was installed but, since my user directory was encrypted in /home/username/.Private using encryptfs, it failed to mount, and I didn't find a workaround yet, since no username nor any passwork seems to work, even typing the exact terms I entered during install. So I can only access a Guest account, which dosn't allow me to access any Terminal nor sudo neither any graphical interface that requires root.
It seems that alternate install doesn't have the necessary packages to deal with encryptfs, since it doesn't understands its partition type. I tried to get into recovery other times to try to figure out something, using the bash, in fstab, but nothing works. Even adding /home/username/.Private /home/username encryptfs defaults 0 0 makes the installed system (either the installed or the recovery from the alternate CD) tell me it is not a valid partition.
Maybe the instalation procedure in the common CD and ALSO in the alternate CD should be changed to alert users that if they have an encrypted LVM, they probably don't need an encrypted home. When I did this mess I was really thinking I was making a separate /home partition.
I also tried this one: http://ubuntuforums.org/showthread.php?t=823929 using the normal CD.
This didn't work for me. I did everything hastala told us to do and started the install procedure. It failled in just substituting the previous system (only erase /root, /bin, etc.). It wanted to format the whole partition. Since I have /home and / in the same encrypted lvm partition, it wouldn't wwork for me.
