bug#62217: Ungoogled-chromium doesn't launch with linux 6.2

[Nicolas Graves via Bug reports for GNU Guix]

Hi!

I've updated linux to version 6.2.2 (the nonfree version), and since
then I can't launch ungoogled-chromium-wayland.

Nyxt or Firefox-like browsers work fine. 

Here's what I tried :

guix shell gdb -- gdb /gnu/store/1jmlqw987ifnb3abr0s2hvihcg1n2xmx-ungoogled-chromium-wayland-109.0.5414.119-1/bin/chromium

yields 

"/gnu/store/1jmlqw987ifnb3abr0s2hvihcg1n2xmx-ungoogled-chromium-wayland-109.0.5414.119-1/bin/chromium": not in executable format: file format not recognized

Thanks if you can fix this quickly.

Can you reproduce in linux-libre?  A `guix system vm` should be enough
to test this.

I've run into this message in the past when my store got corrupted (in my 
case it was a full disk on a computer that has other evil spirits living 
in it as well). Can you check with `guix gc --verify=contents`? If it 
reports anything, you might be able to repair it with `sudo guix gc 
--verify=contents,repair`.

For what it's worth ungoogled-chromium works for me with Guix commit 
5312d798ac36a72d8a977325a7c6ff7647be670a.

Best,
Jack

I believe the error is because chromium is a shell script wrapper and
not an ELF binary.

I used the following script for those:

--8<---------------cut here---------------start------------->8---
$ cat ~/.local/bin/run-gdb
#!/usr/bin/env bash

(
        wrapper=$(cat $(which $1))
        shift
        . <(echo "$wrapper" | grep ^export)
        binary=$(echo "$wrapper" | grep ^exec | grep -o -E '/gnu/store[^"]*')
        gdb --args "$binary" "$@"
)
--8<---------------cut here---------------end--------------->8---

Then you can do:

--8<---------------cut here---------------start------------->8---
run-gdb chromium
--8<---------------cut here---------------end--------------->8---

Hope that helps,
