Segmentation fault upon launch on vanilla 22.04 LTS

[brettbryantgmail]

I know the reigning advice is to update libc >= 2.31, however this is running the following:

libc-bin/jammy,now 2.35-0ubuntu3 amd64 [installed,automatic]
libc6/jammy,now 2.35-0ubuntu3 amd64 [installed,automatic]

Below is the segmentation fault:

Can you update glibc anyways? There's a chance an update happened on the build machine as well, I may need to update the docs.

[brettbryantgmail]

To what? There’s nothing more in the package manager. Do you have a version in mind I need to update to?

My bad, I was preoccupied and didn't pay close attention.
I can't think of anything right now that could be causing this, does look like glibc but could be the other way around, too high a version?
I'll check for that and get back to you.

@Zapotek I think the main problem is ffi lib. Check my post: #1071
if it helps, running version v1.5.1 & WebUI v0.5.12 doesn't have this issue.

[Zapotek]

@afonsofsgomes @brettbryantgmail can you please check your libffi-dev version?

apt-cache policy libffi-dev

I'm on 3.4.2 and everything is working fine.

[brettbryantgmail]

libffi-dev:
Installed: (none)
Candidate: 3.4.2-4
Version table:
3.4.2-4 500
500 http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages

This issue should be easily reproducible in a VM with a fresh install of Ubuntu 22.04 for you to work with.

[Zapotek]

Tried that, no problem at all, it worked fine.

[lukyanovanastya]

got the same issue on VM with Ubuntu 22.04 and glibc 2.35
