Cannot use ./launcher enter app

Installation
1

I am trying to enter the console, but when I use

./launcher enter app

I get this very cryptic error.

Running on ubuntu 22.04, fresh install.

root@discourse:/var/discourse# ./launcher enter app
x86_64 arch detected.
OCI runtime exec failed: exec failed: unable to start container process: open /dev/pts/1: operation not permitted: unknown

Equivalent docker command fails the same way.

root@discourse:/var/discourse# docker exec -it app  /bin/bash --login
OCI runtime exec failed: exec failed: unable to start container process: open /dev/pts/1: operation not permitted: unknown

Sounds like a bug on runc 1.1.3 per

Can you check your containerd / runc versions?

if it helps, on my ubuntu 22.04.1 sandbox, enter app works with

runc version 1.1.3
commit: v1.1.3-0-g6724737
spec: 1.0.2-dev
go: go1.17.13

I saw this on an AWS EC2 client today. It was a screen share, though, so I can’t get the version information.

It happened both with ./launcher enter app and docker exec -it app bash.

Use these commands to get the version information:

sudo containerd -c
sudo runc -v

I’m the client and yes it happened on my machine.
Please tag me if you’ve solved this somehow @TechAUmNu

You need to run those commands on the VM where it was broken and report the version information here.

Have you been able to solve it?

Oh. Sorry. I don’t have an answer. I guess it was your machine where I saw it and I haven’t touched another aws machine.
