Subiquity crashes installing grub-pc with noble daily build

[Guillaume]

Creating a master under QEMU for noble, subiquity crashes when installing grub-pc.

2 things to note :
- our setup works well with u22
- we can create our master using QEMU or VMWare, and subiquity only crashes when using QEMU, everything is fine if we use a VMWare VM

Hello and thank you for your bug report,

Could you please attach the curtin-install.log file that should be available in /var/log/installer?

Thank you,
Olivier

Here's the curtin-install.log you requested, thanks for taking a look at this.

[Olivier Gayot (ogayot)]

Hello, it looks like the curtin process (or the apt-get process?) got killed.

That could mean that your VM did not have enough memory. How much memory did your QEMU VM have?

1 Gb and it seems not enough for noble, altough it's enough for jammy.
I'll try with 2 and 3 Gb to see if it's enough, thanks.

[Guillaume (e1msih)]

2 Gb of ram isn't enough, 3 Gb ram is okay.
It seems a lot for a text installation, but it's not an isolated case, as RHEL 8 & 9 have the same issue, in my case (U22 / EL 7 and inferiors build well with only 1 Gb).
