Upgrade Issues, 10.04 Netbook to 11.04

Asked by Red

I'm running 10.04 Netbook Remix on an Acer Aspire One. I'd love to upgrade to 11.04, but I've run into issues. When I try to upgrade directly using the Update Manager, it tells me that there is a problem with my connection and cannot download the upgrade. I am unaware of any connection problems, and was able to download and install all 10.04 updates that were available. So I downloaded it directly from Ubuntu. I do not have a CD drive so cannot burn it to a CD, and I am not willing to give up my only flash drive as a boot drive, I can't risk the information that's on it. The ISO downloaded just fine, but since I'm not in Windows, Wubi is useless, and I cannot for the life of me work out what I should be doing with this ISO. I'm hoping there's just something embarrassingly obvious I'm missing, rather than any real troubles.

Thanks
Red

I never use it, but it seems to work. As you don't have a CD driver, you will have to mount ISO image as explained.

But before, you told you use 10.04 which is a LTS. By default, update-manager upgrade from one LTS to another one, i.e. 12.04. Open update-manager, click on button preferences, uncheck "Upgrade only to LTS" and see if you get a new button to upgrade to Natty 11.04/

The second paragraph was not the issue, it was already set to recognize all normal upgrades. There was a button to upgrade to 11.04 already, it's just that when it is pressed, an error appears telling me that it "Could not download release notes. Check internet connection and try again." As I mentioned previously, I highly doubt the connection is at fault. Especially since I've seen another question on here with a user receiving the same error. Thanks for the idea, though.

As for mounting the ISO...now what? Sorry if this is a noobish question, but I honestly have no idea what I need to be doing. I can browse the disc image, just as I could before. Should it be auto-running? It is not. I'll try downloading the file again, from an alternate source, and mount that, in case it was corrupted.

P.S. I tried the commands given if the upgrade dialog box doesn't appear. Nothing happens. The CD is mounted, no error messages are given. But nothing happens.

P.P.S After downloading again and mounting as above, nothing happened once more. Again, I followed the given commands, and this time at least a box popped up saying that the CD would change my system and so I had to input my password. After doing so, nothing happened.

Please note that the upgrade path as designed is from 10.04 to 10.10 and then from 10.10 to 11.04
A direct upgrade from 10.04 to 11.04 is not advised. Skipping releases can only be done with LTS to LTS upgrades (10.04 to 12.04).

The recommended way for you would then be:
download the 10.10 alternate iso
mount it (something like sudo mount file.iso /cdrom -t iso9660 -o loop)
execute the cdromupgrade program on that mounted device
This should lead to a 10.10 system
perform all upgrades on 10.10
mount the 11.04 alternate iso
execute the cdromupgrade program on that mounted device

I have downloaded 10.10. I have mounted 10.10. Nothing happens. There is no "cdromupgrade" program, regardless of where I download it from, and the line

gksu "sh /media/cdrom/cdromupgrade"

suggested in the link provided in the first reply does nothing. No errors, no crashes, no output of any sort, just nothing.

Well. I still have no idea why any of the alternative methods did not work properly, but the Update Manager is now upgrading my system. This leads me to believe there was a problem on the other end that has since been resolved. Thanks for the assistance.
