restricted block probing does not probe NVMe controllers

[Akbar Hamaminatu]

I have trouble installing ubuntu 24.04 with the new ubuntu installers, after "Install recommended proprietary software?" section and clicking next, after a few second I got a crash report and then during "How do you want to install ubuntu?" section, no option given, so I can't continue to the next step.

Hello,

The initial block probing request took too long and timed out after 180 seconds. What took so long seems to be the operation meant to determine the minimum size of NTFS partitions (e.g., sda4, sda1).

After the timeout, we started another probing request that disables the "slow" operations. Sadly it does not probe NVMe controllers - which is what lead to the crash.

Thanks,
Olivier

I opened https://github.com/canonical/subiquity/pull/1978 to fix this issue.

Hi,
Just searched google and I can also confirm the above installer error, but with different hard disk setup.

I have three hard disks all SATA no SSD, no LVM just standard partitions with MBR on first two disks and gpt on sdc

sda mbr partition
sdb mbr partition
sdc gpt partitions

Would disconnecting drives sda and sdb help?
My NTFS partition for windows is on sda ONLY

sdb and sdc contain ext4 partitions.

Ubuntu 22.04 did not have this error, only 24.04 installer
Thanks in advance

Hello Andy,

Would you mind filing a separate bug report (with logs) for the issue you encountered?

The description does not make it obvious but this bug is specific to NVMe controllers.

Thanks,
Olivier

I just found this bug after submitting a duplicate. Thanks for committing a fix, Olivier! Is there any chance to use the fixed version before Ubuntu 24.10? If not, can I somehow install Ubuntu 24.04 Desktop without the Subiquity installer?
