Important Note on 12.04

by lushys / April 27, 2012 10:52 AM PDT


I just wanted to note to everyone there is a current known bug with 12.04 in which 12.04 will NOT install on systems without pae.

Also, I have noticed some problems with VMware, thus having to convert a lot of appliances to OVA/OVF and launch in Virtualbox.

Obviously with a new release there will always be issues. However how can you release something as non-beta with a major issue such as inability to install on systems without pae abilities. C'mon boys.

I however did not notice this issue with the new version of Linux Mint. Which makes no sense as both are Debian and Mint is basically Ubuntu but... a little more lame. (I'm a CentOS guy).

So all those that want to convert/upgrade be aware before you blow your arrays or drives.

When a fix is posted I will update this thread.

Not a bug
by 3rdalbum / April 28, 2012 4:43 PM PDT

This is intended behaviour. It's a bump in the minimum system requirements.

If you said "Ubuntu won't boot on a computer with 64 MiB of RAM", that's another example of something that's not a bug. It's something that was carefully decided on.

The vast majority of computers that can satisfy Ubuntu's other system requirements are also PAE-compatible. Or, to put it a different way, most computers that aren't PAE-compatible are also too weak to run Ubuntu anyway.

PAE does solve the issue of "Ubuntu only reports 3.2 GiB of RAM when I've got 8 GiB!", which I gather has been a common reason to dial the helpline.

Actually, do a little more digging.

Issue resolved:

So it was a bug, sorry I didn't include the original Ubuntu team notification that was sent out.

Also note that the VMware issue is still not resolved. Installation rejects the current kernal. Solution on some machines seems to be that 3.0 will work and 4.0 will crash when attemping to launch an appliance.
