Failed upgrade from 7.10 to 8.04, using Alternate CD
Hi guys,
When upgrading from 7.10 to 8.04 using 8.04 alternate CD, it gave me error info: Code:
Could not calculate the upgrade A unresolvable problem occurred while calculating the upgrade. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu If none of this applies, then please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bugreport. 1, Mount iso using Code:
sudo mount -o loop ubuntu-8.04-alternate-i386.iso /cdrom Code:
gksu "sh /cdrom/cdromupgrade" 4, Update Manager asked me whether include latest update from Internet, I chose "No" 5, When calculating changes, Update Manager pop up a error screen contains info i gave above. Here is my /var/log/dist-upgrade/main.log file: Quote:
If I chose "Include latest update from Internet" YES in above step, update manager would also crash, the only difference was that it gave no error information explicitly. After checking /var/log/dist-upgrade/main.log, it gives: Quote:
Thank you guys! NOTE: I've done Code:
sudo apt-get autoclean sudo apt-get update sudo apt-get upgrade

Re: Failed upgrade from 7.10 to 8.04, using Alternate CD
leeyee, when I inserted my 8.04 alternate cd, the window opened up with the files but a message box popped up asking if I wanted to use the distro off it (not those words, but something similar). I clicked on yes and then it added it to my list of cd's to work off in synaptic pkg manager (update manager as well) as a source. I did my upgrade that way without problems.
Which instructions were you following to do the upgrade? Just curious if there is something in those instructions that were wrong or maybe we missed a step? Maybe someone else will post that has encountered this or knows what causes the upgrade to fail.

Leeyee,
I was reading the instructions on the upgrade and you have to burn the iso to a disk. It appears that mounting the image off your hard drive doesn't work. Kay

I dont know whether burning it to a disk will change it or not but I had this happen during a standard upgrade so it might be something besides burning it to a disk

Re: Failed upgrade from 7.10 to 8.04, using Alternate CD
Hey
I've fixed it. Burn it really can resolve the problem, but i got a better way: Code:
sudo mount -o loop ubuntu-8.04-alternate-i386.iso /cdrom sudo apt-cdrom -m -d /media/cdrom add
