Added journalctl -xb log.

[Jeff Lane  (bladernr)]

Wonder if this could have been related to the package rebuild for the XZ vulnerability.

[wang (dong28)]

Hi jeff，
i had a try on the same machine, the latest ISO daily build version has no this issue and install successfully now.
QA will double confirm tomorrow, once get result, i will update on launchpad.
Thanks

[wang (dong28)]

Hi Jeff,
QA did verification on the same machine and this issue occur again.
we installed 4-5times and all installtations are failed. They have same error log as before.
It is weird, yesterday i install 3 times use the same ISO and install successfully for each time...
I speculate that this issue might be triggered by some configuration or some case.

[panreyes (panreyes)]

I'm not sure if this is the same bug, but in my case the installer was not able to complete the installation, and kept on the same message "curtin command target-in".

I "completed" it by executing 'killall -9 unattended-upgrades'

I'm not sure if this is related to the installer being a beta debug version or not, but it didn't complete after 16 minutes. I was installing it in a VirtualBox VM on a pretty fast CPU (4x cores from a Ryzen 7 5800X), with NVME storage, 16GB of RAM and 1gbps internet connection (actually 10gbps, but I still have to upgrade a switch).

This happened selecting the 3rd party drivers option and it also happened without that option.

Here's a small excerpt of the subiquity-server-debug.log:
2024-04-22 23:20:53,297 DEBUG root:38 start: subiquity/Install/install/postinstall/run_unattended_upgrades/cmd-in-target: curtin command in-target
2024-04-22 23:36:55,887 ERROR subiquitycore.utils:209 Unattended upgrades exited with result: 1

I wonder if it just was updating my system, but because I had no feedback from the installer I couldn't tell.

[Dan Bungert (dbungert)]

@panreyes - in your case, it probably was legitimately installing updates. RC images should be available soon, I expect you'll see cleaner results with that.

[Dan Bungert (dbungert)]

@wang - for your case we'll need more than the journal. Please post a full copy of the contents of /var/log/installer (in a new private bug if you don't want that on a public one)

[Josh Smith (coin-tengoku)]

Same issue as @panreyes reported except I let it sit for about an 1 and a half and it successfully completed installation without error.

[Josh Smith (coin-tengoku)]

*Hour and a half

[wang (dong28)]

Tested the latest daily build version and it has the same issue.
installer log has been uploaded, you can download in attachment, thanks!

[panreyes (panreyes)]

For sake of confirmation, I tried again and yes: it takes a long time without any messages but it completes the installation.

2024-04-23 11:16:14,281 DEBUG root:38 start: subiquity/Install/install/postinstall/run_unattended_upgrades/cmd-in-targe>
2024-04-23 11:53:53,037 DEBUG root:38 finish: subiquity/Install/install/postinstall/run_unattended_upgrades/cmd-in-targ>

It took 37 minutes to complete unattended-upgrades, but it made it :)

[wang (dong28)]

Hi panreyes,
In my case, when meet this log, it will report error and exit the installation process. i attached the shotscreen on attachment.

[ehson Hussian (ehson-husain)]

Same issue, RC installer not working for me...

[ehson Hussian (ehson-husain)]

Update: I could install by _not_ connecting to the internet

[wang (dong28)]

yes, don't connect internet and without cable i can install successfully too. In case of with cable and network cannot access to internet, meet this error will cause install fail.
