Ubuntu hanged while upgrading from 10.10 to 11.04

Hi,

Ubuntu 11.04 is still in the beta phase = not for production use = use at your own risks.
If your computer works well with 10.10 does not necessarily means it will work as well in Ubuntu 11.04.

Thus you shouldn't upgrade blindly : always use a live CD/USB to test for your hardware first.

In your case, I don't know how to revert the situation. As for your files, the best thing would be to boot your computer with a live CD and then mount your hard disk and backup your essential data files to an external USB storage device.

Hope that helps.

I appreciate the fact 11.04 is still beta, just not sure if it's helpful to report the *many* bugs or not? I'm not being facetious in the slightest, 11.04 is as gorgeous as my ex-g/f (no, our breaking up was not mutual, sigh). I adore 11.04, but unsure if reporting the huge amount of bugs is overkill or helpful...or?

Anyway I'll just tack this comment on here, as after I installed it successfully once (and loved it), it did eventually crash and since then, it just hangs saying "Installation complete, need to restart" - but it won't let me shut down. If I restart and load it up, I usually get the issue Raza had above, login screen and time, just hanging...this has happened 4-5 times I think fwiw.

cheers guys!

Hi,

I can remember that there was issues depending on the hardware. I usually play safe by choosing hardware I know won't give problems with Linux, e.g. Intel graphic chipsets etc.

With computer giving problems, you may try to boot with acpi=off and see what the result would be.

To do so, once the computer starts to boot, you need to keep pressed down the SHIFT key to show up the grub menu. Then you need to edit the first boot line by pressing "e" and then add at the end of the boot command line "acpi=off", then boot the computer with the modified command line (CTRL+x).

Please refer to the section "Editing menus during boot" from this document:
https://help.ubuntu.com/community/Grub2#Boot%20Display%20Behavior

Hope that helps.

@Raza

Were you able to fix this problem? Did you end up reporting a bug? Do you still want further assistance?

If you completed your installation of Ubuntu 11.04 Natty, were asked if you wanted to reboot or continue testing it, opted to continue testing it, and then found that you had no obvious working way to reboot, you probably suffered from bug 661250. I recommend you go there, read the description, and if you were affected by it, indicate that you were affected by clicking the green "This bug affects" link near the top of the page, and if you have any information that is not present in that bug report, post a comment to provide it. You might also want to subscribe to the bug, so you are informed of progress on it, and so it's easier for Ubuntu developers and others to contact you for more information (since you'll be notified of any comments that are posted).

If you are unable to restart but not affected by that bug, then you are probably affected by another bug.

You could be affected by that bug (or another bug) separately from being affected by the other conditions you've experienced.

As for the question of whether or not it's worthwhile to report bugs, the answer is yes, because if nobody reports them, they don't get fixed. However, generally speaking, you should search to see if your bug has been reported, before reporting it. This, and other absolutely essential information for the proper reporting of bugs in Ubuntu, is discussed in https://help.ubuntu.com/community/ReportingBugs -- that page should be read carefully before reporting Ubuntu bugs.

If you're still interested in testing Natty, I recommend that you try installing from a daily-live image (http://cdimage.ubuntu.com/daily-live/current/), see if you're still able to produce the problem, and if so, report it as a bug. You might want to start a question about it before reporting it as a bug, if you want help making sure you're going about testing in the right way, and ensuring that you're providing all the necessary information. (This is a matter for a separate question, and not this one...though if you've experienced the same problem as Raza, and the problem goes away when you use the daily-live, then that is definitely on-topic for this question!)
