Can't upgrade from 8.0.2 to any newer version with an old CPU without avx2

plhardy · Mai 25, 2026, 2:21

Due to recent security issue i was trying to upgrade a yunohost app peertube on an old system.

It did fail at upgrade, service peertube fails

2026-05-25 14:46:54,471: WARNING - mai 25 14:46:45 systemd[1]: Started peertube.service - PeerTube: video streaming platform.
2026-05-25 14:46:54,471: WARNING - mai 25 14:46:49 systemd[1]: peertube.service: Main process exited, code=killed, status=4/ILL

2026-05-25 14:46:54,472: WARNING - mai 25 14:46:49 systemd[1]: peertube.service: Consumed 4.946s CPU time.

and dmesg allowed me to find out culprit :

[ +4,611232] traps: MainThread[89118] trap invalid opcode ip:7f22c8f3d2e8 sp:7ffc33966e00 error:0 in libvips-cpp.so.8.17.3[7f22c8d0a000+a7b000]

That is related to a thumbnail rebuilding feature in peertube 8.1.0 using sharp library ( https://www.npmjs.com/package/sharp ) relying on libvips ( GitHub - libvips/libvips: A fast image processing library with low memory needs. · GitHub ) requiring cpu with avx2 support.

Given the old system used for it and that i can’t get hand on the hardware which is at 1200km away … this will be a challenge …

so i am sitll on 8.0.2 that i did patch manualy using What versions are affected by security issues corrected by v8.1.6? · Issue #7622 · Chocobozzz/PeerTube · GitHub

Can’t do better now.

Hi,

Can you try Prebuilt sharp not working with some CPUs · Issue #7495 · Chocobozzz/PeerTube · GitHub?

Thanks @Chocobozzz

this was not as simple as expected since there is not a full procedure to build libvips for this sharp usage.

finaly i got it working, reading various github posts, custom libvips should be installed globally using meson build –prefix /src.

This is dangerous if any debian libvips is already installed. i didn’t check if i could debian one, but i thing there would be a version problem, and a conflict.

This is really a patch solution not following gold stand standard for yunohost, but at least, it fixed my problem.

i mention it here but THIS IS TWEAK AND RISKY TO USE THIS

yunohost app install GitHub - artlog/peertube_ynh at no_avx2 · GitHub

It has interest to see build procedure used :

github.com/artlog/peertube_ynh

scripts/_common.sh

no_avx2

	#!/bin/bash

#=================================================
# COMMON VARIABLES AND CUSTOM HELPERS
#=================================================

# Obtain the (empty string), __2, __3, cf the DB suffix in production.yaml...
db_suffix="$(echo $app | sed 's/peertube//g')"

build_vips() {
    # as root
    apt install build-essential pkg-config libglib2.0-dev libexpat1-dev meson
    pushd /home/yunohost.app/peertube/
    vips_pkg_name=vips-${vips_version}
    # don't download it twice
    if [[ ! -d ${vips_pkg_name} ]]
    then
	if [[ ! -e ${vips_pkg_name}.tar.xz ]]
	then
	    ynh_hide_warnings ynh_exec_as_app wget https://github.com/libvips/libvips/releases/download/v${vips_version}/${vips_pkg_name}.tar.xz

for npm sharp this is in install or upgrade scripts , a direct adaption of proposed fix.
