[Problem Description]
Subiquity fails to execute when running on ARM64 with -64k Kernel. It exits with the "Segmentation fault" message
[Additional Info]
The problem seems to be with python3.8 binary in the snap. The same problem occurs with wget binary in the same snap, but ubuntu-distro-info works fine. Both python3.8 and wget are statically compiled, while ubuntu-distro-info is not.

Works
Tried other kernels (5.17, 5.19) with the same error.

1. Run a VM in ARM64 architecture:

2. Connect to the VM and install a -64k kernel

3. Reboot in the kernel (I disabled secure boot)

[Problem Description]
Subiquity fails to execute when running on ARM64 with -64k Kernel. It exits with the "Segmentation fault" message
[Additional Info]
The problem seems to be with python3.8 binary in the snap. The same problem occurs with wget binary in the same snap, but ubuntu-distro-info works fine. Both python3.8 and wget are statically compiled, while ubuntu-distro-info is not.

patchelf (in the version bundled with snapcraft) creates segments that overlap when aligned to a page size greater than 4k, e.g. from readelf -h on the python3.8 interpreter in the current subiquity snap:
LOAD 0x000000 0x00000000003ff000 0x00000000003ff000 0x001000 0x001000 RW 0x1000
LOAD 0x001000 0x0000000000400000 0x0000000000400000 0x4bab44 0x4bab44 R E 0x1000
This makes the kernel very unhappy indeed and it refuses to load such a binary (execve returns EINVAL). Upstream patchelf fixed this in https://github.com/NixOS/patchelf/pull/216. I don't know if cherry picking that fix or just updating the version of patchelf bundled by snapcraft to the latest release is more appropriate.

The same VM, using the non -64k kernel works:
# uname -a
Linux jammy-arm 5.15.0-27-generic #28-Ubuntu SMP Thu Apr 14 12:56:31 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux
# /snap/subiquity/4236/usr/bin/python3.8 -c "print('Works')"
Works
Tried other kernels (5.17, 5.19) with the same error.
[Reproducer]
1. Run a VM in ARM64 architecture:
virt-install --arch aarch64 --boot uefi --osinfo detect=on,require=off --name jammy-arm --memory 8096 --vcpus 4 --disk=jammy-server-cloudimg-arm64.img,bus=virtio --disk=jammy-arm-seed.qcow2,bus=virtio --network network=default,model=virtio --boot hd --noautoconsole
2. Connect to the VM and install a -64k kernel
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/bootstrap/+build/23546569
3. Reboot in the kernel (I disabled secure boot)
# uname -a
Linux jammy-arm 5.15.0-27-generic-64k #28-Ubuntu SMP Thu Apr 14 19:01:31 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux
4. Install subiquity
sudo snap install subiquity
5. Try to run it
# /snap/bin/subiquity
