Cannot prepare kernel-latest-vm package

Why can’t I qubes-prepare-vm-kernel from the kernel-latest(s)?

I can prepare it from all 5.15.x but not for 6.x.

When trying, for example

[user@dom0 ~]$ sudo qubes-prepare-vm-kernel 6.1.1-1.fc32.qubes.x86_64 6.1.1-1.qubes

I get an error

There are plenty of space in /tmp, but actually mounted dev/loopxx device in folder /tmp/qubes-modules-6.1.1-1.fc32.qubes.x86_64 is being reported as

No error ever for preparing kernels from those shown under

The R4.1 version of /usr/sbin/qubes-prepare-vm-kernel creates a filesystem image limited to 400 MiB. I’d try editing that script to use a larger value.

In R4.2 it’s 768 MiB and the contents have been trimmed down too.

Jesus, did it!

Just edited line 34 to 768 and succeeded! You’re fantastic with your responses, 100% with me at least. Thank you so much!
