Bug Description

Release note:

On some machines, the CD boot fails with the message "The installer encountered an unrecoverable error, A desktop session will now be run so that you may investigate the problem or try installing again." If you encounter this error, simply click okay to load the live CD desktop. Click on the "Install Ubuntu 10.04" icon to begin installing Ubuntu.

Original report follows:
I downloaded Ubuntu Lucid daily-live (64-bit version) and burned it onto a DVD-R (not a CD-R). Booting from the DVD gets past the Ubuntu logo with five dots, a purple background and the mouse pointer is shown, then the following message appears in a dialog box:

"The installer encountered an unrecoverable error, A desktop session will now be run so that you may investigate the problem or try installing again."

After pressing the OK button, Ubuntu shows the message "Please remove the disc and close the tray (if any) then press ENTER." and reboots after that.

The first time I had this issue was on Thursday, today I zsynced and burned the image onto another DVD, but the same problem still appears.

Unfortunately, I couldn't find the file /var/log/installer/debug, the only file with the same folder was /var/log/installer/dm.

Also, it seems apport-collect 567899 did not work correctly. I ran it and it opened a web page where I could put my e-mail and password of OpenID, but the button "Continue" wasn't a link (it looked like normal text). Moving the cursor to the text "Continue" and pressing Enter did nothing.

japro's issue appears to be udisks' hitting the dbus timeout on a call to its inhibit method:
Inhibit all polling failed: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
As ubiquity is wrapped by udisks --inhibit, it fails along with it.

The installer does launch.

It occurs to me that this problem his been in the live Cds for some time. I am running two test machines and noticed that the initial graphical install screen (the one that gives the user the choice of trying or installing) never appeared on the one having the problem now. It just went straight to the desktop. Now with the RC, it puts up the error message but the error message does not let you continue on to the desktop; it just reboots.

When you see the keyboard icon as the CD is booting, press spacebar. This will bring up the advanced boot options screen. Select a language then arrow down to the "Install Ubuntu" option. Press F6, then escape. You should see a line of text. Change "only-ubiquity" to "maybe-ubiquity" and add a space and "break=bottom" after it. Press enter.

The CD will continue booting and you should end up at an "(initramfs)" prompt. Type `chroot root bash`. Next, type nano /etc/dbus-1/system.conf. Delete the line that reads "<fork/>", save the file (ctrl-o, enter), and exit (ctrl-x).

Now type nano /etc/init/dbus.conf. Comment out the "expect fork" and "respawn" lines by putting a # character in front of them. Change the line that reads "exec dbus-daemon --system --fork" to read "exec strace -tt -o/var/log/dbus.log -- dbus-daemon --system". Save the file (ctrl-o, enter) and exit (ctrl-x).

Type nano /etc/init/ubiquity.conf. Change the line that begins "if ! ubiquity-dm vt7 :0 ubuntu..." to read "if ! strace -tt -o/var/log/ubiquity.log -- ubiquity-dm vt7 :0 ubuntu...". Save the file (ctrl-o, enter) and exit (ctrl-x).

Now type exit to bring you back to the (initramfs) prompt. Type exit again. The CD will continue booting and should crash at the installer, as it did before. Switch to a virtual terminal (ctrl-alt-f2), plug in and mount a USB disk (sudo mount /dev/sdb1 /mnt), then copy /var/log/dbus.log and /var/log/ubiquity.log to it.

While you're at the virtual terminal, type `ps auxf > /mnt/ps.log`.

Unmount the USB disk (sudo umount /mnt) and attach dbus.log, ubiquity.log and ps.log to this bug report.

Vladimir,

Ignore the getpwuid_r() error. That's insignificant.

Please review the instructions. I followed them myself and they produced logs for both ubiquity and dbus, as expected. I suspect you're missing one of the steps if you don't have a ubiquity.log or dbus.log in /var/log. Make sure the first prompt you see after booting from the advanced options screen is "(initramfs)" and not "ubuntu@ubuntu:~$".

Thanks!

Isn't it "exec strace -tt -o /var/log/dbus.log -- dbus-daemon --system" - space beetwenn "-o" and "/var/..."?

William,

Thanks a lot for posting those logs. I've looked over them and traced through the code, but the lack of a decent string size in the output (which I failed to ask you to use) is making it very difficult to follow. Would you be so kind as to try again with the following option added to the strace calls:

-s 1024

That is, follow the steps I outlined in comment #22 (https://bugs.edge.launchpad.net/ubuntu-release-notes/+bug/567899/comments/22), and everywhere you would normally put:
... strace -tt ...

put instead:
... strace -s 1024 -tt ...

This will change the string size from the default 32 characters to 1024, which should be more than enough to show the entire strings that dbus passes around.

Thanks!

Anyone else that's experiencing this bug, please do the same if you are able.

Now type nano /etc/init/dbus.conf. Comment out the "expect fork" and "respawn" lines by putting a # character in front of them. Right below them add a line that says "env DBUS_VERBOSE=1".

Save the file (ctrl-o, enter) and exit (ctrl-x).

Now type exit to bring you back to the (initramfs) prompt. Type exit again. The CD will continue booting and should crash at the installer, as it did before. If it does not crash, try again without the strace call. That is, change the line that reads "exec dbus-daemon --system --fork" to "exec dbus-daemon --system >/var/log/dbus-messages.log 2>&1"

Switch to a virtual terminal (ctrl-alt-f2), plug in and mount the USB disk again (sudo mount /dev/sdb1 /mnt), then copy /var/log/dbus.log and /var/log/dbus-messages.log to it.

== Desktop installer sometimes crashes on startup ==

On some machines, the CD boot fails with the message "The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again." If you encounter this error, restart your computer with the CD inserted, press any key at the splash screen (when you see the keyboard icon at the bottom of the screen), and select "Try Ubuntu without installing". Once the desktop appears, use the "Install Ubuntu 10.04" icon to begin installing Ubuntu. (Bug:567899)

I have a similar issue. The boot time is much longer compared to 9.04 about 2mins vs. 1 minute. I cannot disable a floppy in the BIOS and the laptop has none of that. While the machine is booting the messages are not shown, I can't tell which task takes longer. I'll try to find out how to bring the messages back. I enabled logging.
I also noticed that on a different machine a usb startup disk takes much longer even to get to the screen of the language selection, it is about 2mins vs. 2secs!!!! The performance of Lucid compared to Karmic is also notably inferior, such as video and visual effects.

According to bootchart, I had about 30sec boot time on jaunty, 80secs on karmic and, finally, 100 secs on lucid now. No much difference in the set-up from the rc.d point of view, I remember I got read sendmail at some point.
The trend, for me at least here, that the more boot-up optimization are offered the longer the boot-up time gets.
Also, as I mentioned on a completely different hardware with start-up disk it got just ridiculous.
