Installer blanks after "Getting the current configuration"

[kalligator]

Describe the bug The installer shows blank after a few seconds of "Getting the current configuration"

To Reproduce Steps to reproduce the behavior:

1. Select the Custom (Advanced) option.
2. Click on Custom (Advanced) button on the bottom right
3. 'Getting current information' shows for a few seconds
4. The installer goes blank.

Expected behavior Expecting to see the drives and partitions

Desktop (please complete the following information):

• OS: elementaryos-6.0-daily.20210430

Additional context I hadn't had a problem with ubiquity. I also tried pop-os_20.10_amd64_intel_14.iso and it had no problem. I was wondering how can I debug this.

[davidmhewitt]

Could you try the following to debug:

1. Reboot into the iso again and launch "demo mode" instead of trying to install.
2. Install "d-feet" (sudo apt install d-feet) and launch it from the applications menu
3. Navigate to io.elementary.InstallerDaemon in the left pane (can search for installer to find it quicker)
4. Expand out the sections on the right to get to the following:
5. Double click the highlighted GetDisks entry
6. Enter True in the "Method input" box and press "Execute"
7. Post a screenshot of your output, it should look something like this:

Great, thanks. It's crashing when trying to figure out what partitions/disks already exist. I'll send over some more debugging instructions when I'm back at my PC tomorrow, but could you provide information about the disks/partition layout of your system? Maybe a screenshot from gparted?

[kalligator]

Alright, thanks!

Here are the screens from gparted. The last drive is the usb dongle.

[davidmhewitt]

Thank you!

To debug this further:

1. Boot up the iso in demo mode again. It would be ideal if you could sign into GitHub in the live session because there's going to be a bunch of stuff to copy and paste into the issue report.
2. Modify /etc/apt/sources.list.d/elementary.list and add main/debug on the end of the first line so it looks like this deb http://ppa.launchpad.net/elementary-os/daily/ubuntu focal main main/debug
3. Run sudo apt update
4. Install debug packages with sudo apt install d-feet systemd-coredump gdb io.elementary.installer-dbgsym
5. Repeat the d-feet steps from my first post to cause it to crash again
6. Run sudo journalctl -u io.elementary.InstallerDaemon.service to get the logs from the installer daemon and copy the output for this report.
7. Run sudo coredumpctl debug, you should be at a (gdb) prompt
8. Run bt and keep pressing enter to get more lines until you return to a (gdb) prompt.
9. Copy and paste the whole output from where you ran the coredumpctl command

[kalligator]

Sorry for the late reply. Alright here are the outputs. Unfortunately coredumpctl debug did not work. The debug packages were installed with no objections.

The error from d-feet was different this time:

Looks like it's not crashing anymore. Did something change with your disk configuration or the way you booted the iso? If not, can you reproduce the issue if you execute the GetDisks method a few times? Can you reproduce it if you reboot and try the first debugging steps again without installing the debug symbols?

I suspect the installer may work in this state, since it's not crashing now. But we won't be able to find out what caused the original issue unless you can get a core dump.

[kalligator]

I haven't changed the disk config. I had run apt upgrade out of habit though the first time I posted today.

I rebooted and tried the GetDisks method a few times with the debug symbols installed (and no upgrades) and it kept replying with that timeout (24) message. I then went on to see if the actual installer would proceed but it went blank again, only this time it wasn't within ~10s but it kept scanning the drives for a little longer ~2min. I tried to see if coredumpctl debug would return something this time but nothing.

I rebooted and followed your first instruction msg only and got the original disconnected (4) error.

[davidmhewitt]

Thank you for all your help and patience with this, it's much appreciated!

It seems like installing the debug symbols is "fixing" it somewhat, but not fully, which is pretty annoying since it's making it hard to debug!

Could you try getting the logs again (with debug symbols installed) after waiting the 2+ minutes for the installer GUI to timeout with:

sudo journalctl --no-pager -u io.elementary.InstallerDaemon.service

[davidmhewitt]

I guess another thing that would be interesting is the output of the same command on a boot without the debug symbols installed after you've caused it to crash, either using the GUI or d-feet.

[kalligator]

Output after running GUI installer with debug symbols installed, after the hd scanning sound ended ~2.5min. Installer had blanked at ~2min:

In eOS 6b however I can't get the installer to run from terminal so as to get a direct comparison:

How long does it take for the disks and partitions to show up in the Pop!_OS installer?

[davidmhewitt]

I've opened PR #519 to skip over read-only drives when probing the disks as I've noticed /dev/sr0 in your logs. I guess you have a CD/DVD drive?

.deb files have been built from this PR that you can download here: https://github.com/elementary/installer/suites/2639521946/artifacts/57934344

If you have time and you are able, could you boot the live session again and install those .debs, then retry the installation and see if anything is any different in d-feet response or the logs? You'll have to run sudo service io.elementary.InstallerDaemon restart after installing them.

Otherwise, it'll be a day or so before that code hits the repositories and you'll just be able to do a sudo apt update && sudo apt upgrade after booting the live session to get a version of the installer with that code in it.

It's a long shot, and it probably won't fix your issue, but I'm struggling to find what's wrong!

[kalligator]

The Pop!_OS installer took about 3min, not sure exactly.

Indeed I have a dvdr drive loaded with an empty dvd.

I'll wait for the updated deb version as I'm not sure of the process otherwise.

Thanks!

[davidmhewitt]

An updated version of the installer has now been pushed to the repositories, you should be able to boot the iso again and do the following in the demo session:

sudo apt update
sudo apt upgrade
sudo service io.elementary.InstallerDaemon restart

Then re-test. I still don't think it will work, but it would be interesting to see if there is any difference in the d-feet output without debug symbols installed.

[kalligator]

I just tried that, no go, again d-feet showed the disconnected (4) error and journal Failed with result 'signal' same as in a previous comment.

[kalligator]

Success finally! Turns out I just had to restart the io.elementary.installer process. And detection if fast, under 30s without even upgrading to the newer version, just with what came with the ISO. So perhaps the process in loading too early initially?

[davidmhewitt]

Interesting! What happens if you boot the iso, don't do anything and wait like 5 minutes for it to do disk probing in the background, and then trying to install?

[kalligator]

Well, it turns out it wasn't because of restating the process after-all. When I tried to proceed to the next step and actually perform the installation it failed because I had mounted a partition, the large "storage" ntfs one (sda4). In retrospect hat's why it finished probing faster as well. I then retried with that partition unmounted and it wouldn't show the disks/partitions panel. Then I mounted it again, reached the disks/partitions panel, unmounted it, selected the mount points for the new installation and it proceeded! The computer restarted without warning, after what want to believe was a successful installation.

Perhaps the installer chokes if large partitions are present? Mine's 2.32T

[davidmhewitt]

Hm, very odd, I doubt it's anything to do with partition sizes. As you say, it works on Pop!_OS and there aren't that many differences. I have one more idea to try getting some debugging information:

1. Boot the iso, upgrade the installer and restart the service as per my previous post:
2. Install debug tools, but not the dbgsym package:

1. Modify /etc/apt/sources.list.d/elementary.list and add main/debug on the end of the first line so it looks like this deb http://ppa.launchpad.net/elementary-os/daily/ubuntu focal main main/debug
2. Run sudo apt update
3. Install debug packages with sudo apt install d-feet systemd-coredump gdb

3. See if the installer crashes using either the GUI or d-feet
4. If it does, see if there are any core dumps with sudo coredumpctl list
5. If there is a core dump, then install the debug symbols with sudo apt install io.elementary.installer-dbgsym
6. Run sudo coredumpctl debug, you should be at a (gdb) prompt
7. Run bt and keep pressing enter to get more lines until you return to a (gdb) prompt.
8. Copy and paste the whole output from where you ran the coredumpctl command

[kalligator]

still a mystery :) 3. d-feet crashed with Timeout (24) 4. No coredumps found.

[davidmhewitt]

Well this is frustrating! Thank you so much for sticking with it. I'll have a go at creating a VM with a bunch of partitions like yours and see what happens.

What about this:

1. Install just gdb: sudo apt install gdb
2. sudo service io.elementary.InstallerDaemon stop
3. sudo gdb io.elementary.installer-daemon
4. At the (gdb) prompt, type r and hit enter
5. Reproduce the issue with the installer GUI
6. Does gdb see a crash? It will return to a (gdb) prompt by itself if it does. If so, run bt at the prompt and keep pressing enter to get more lines until you return to a (gdb) prompt. Type q and hit enter to quit gdb.

If gdb did see the crash, you could then also do the following:

1. Install the debug symbols with sudo apt install io.elementary.installer-dbgsym
2. Repeat steps 3-6 from above.

[kalligator]

5. The installer blanked. 6. I waited a couple more minutes after the probing sound stopped, but gdb did not register a crash. It did notice an error though. I pressed ^C, bt then a few Enters to catch any possibly useful info.

The bug is still present in the official 6.0 release. To clarify the workaround (that works for me anyway), as I've seen a couple of people mentioning this problem recently, is to:

1. Go into demo and mount your large NTFS partition(s). Ie: just click on the name of the partition on the left sidebar of the file manager so that you can see the files and folders it contains.
2. Click on the Install to disk icon, then Custom installation. You should now be able to see all your disks and partitions.

I have the same issue. I'll try @kalligator workaround. I'm trying to install the latest version available to download (stable 20210810).

That worked here. Thanks @kalligator
