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. root@jammy-arm:~# file /snap/subiquity/4236/usr/bin/python3.8 /snap/subiquity/4236/usr/bin/python3.8: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /snap/core20/current/lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0, BuildID[sha1]=bad3f5d001ec1e2ec539f16d8f6729a06cdd68df, stripped root@jammy-arm:~# /snap/subiquity/4236/usr/bin/python3.8 Segmentation fault root@jammy-arm:~# ldd /snap/subiquity/4236/usr/bin/python3.8 not a dynamic executable root@jammy-arm:~# file /snap/subiquity/4236/usr/bin/wget /snap/subiquity/4236/usr/bin/wget: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /snap/core20/current/lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0, BuildID[sha1]=0f2234825d67c22b6b320139445759f6662aa01e, stripped root@jammy-arm:~# /snap/subiquity/4236/usr/bin/wget Segmentation fault root@jammy-arm:~# ldd /snap/subiquity/4236/usr/bin/wget not a dynamic executable root@jammy-arm:~# file /snap/subiquity/4236/usr/bin/ubuntu-distro-info /snap/subiquity/4236/usr/bin/ubuntu-distro-info: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /snap/core20/current/lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0, BuildID[sha1]=5d8c4c52d7ce614024eba1ba9069e48ad4192508, stripped root@jammy-arm:~# /snap/subiquity/4236/usr/bin/ubuntu-distro-info ubuntu-distro-info: You have to select exactly one of --all, --devel, --latest, --lts, --stable, --supported, --supported-esm, --series, --unsupported. root@jammy-arm:~# ldd /snap/subiquity/4236/usr/bin/ubuntu-distro-info linux-vdso.so.1 (0x0000fffe72270000) libc.so.6 => /snap/core20/current/lib/aarch64-linux-gnu/libc.so.6 (0x0000fffe720b0000) /snap/core20/current/lib/ld-linux-aarch64.so.1 => /lib/ld-linux-aarch64.so.1 (0x0000fffe72280000) 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.
