[06:16] <juergh> linux-buildinfo?
[09:14] <arighi> juergh, you mean using linux-buildinfo instead of linux-doc to determine the kernel version? That makes sense to me, but we still need to patch dkms (and potentially there's something else that is explicitly referring to linux-doc)
[11:38] <matttbe> Hello, I'm using Ubuntu devel (Noble). With the last kernel 6.8.0-11 (based on the rc4?), Firefox Beta (installed from Mozilla's repo) doesn't work: each tab crashes (I didn't check more). If I switch back to v6.6, I can continue to use Firefox. Is it a known issue? Should I report it elsewhere?
[11:38] <matttbe> (I didn't see anything on https://bugs.launchpad.net/ubuntu/+source/linux/+bugs, but maybe I'm not looking at the right place)
[11:42] <matttbe> (BTW, not related to this issue with Firefox, but to the kernel: it would be nice to align IPRoute2 version (6.1) with the kernel one (6.8) :) → https://bugs.launchpad.net/ubuntu/+source/iproute2/+bug/2051672 )

[12:53] <arighi> matttbe, I'm on the latest 6.8, firefox seems to work for me, is this happening also with the stock firefox (from snap)?
[12:58] <matttbe> arighi: thank you for your reply! (and thank you for virtme-ng :) ). Sorry, I don't have Firefox from Snap. I don't know if I can have both at the same time. I installed the packages from https://hacks.mozilla.org/2023/11/firefox-developer-edition-and-beta-try-out-mozillas-deb-package/
[12:58] <matttbe> I have Thunderbird installed from snap and it works well.
[12:59] <matttbe> or maybe there was a bug in the v6.8-rc4?

[13:04] -ubottu:#ubuntu-kernel- Launchpad bug 2046844 in qutebrowser (Ubuntu) "AppArmor user namespace creation restrictions cause many applications to crash with SIGTRAP" [High, Confirmed]
[13:06] <arighi> oh indeed! good point ogra_, I thought that was fixed already in the AA userspace, but apparently it's still an issue
[13:07] <ogra_> well, it requires a profile for each and every of these non-archive browsers ... i doubt that will be fixed quickly 
[13:08] <ogra_> (beyond the known packages from the  archive, which are probably already fixed)
[13:09] <arighi> maybe a quick workaround can be to just `echo 0 | sudo tee /proc/sys/kernel/apparmor_restrict_unprivileged_userns`?
[13:14] <ogra_> there is a workaround for firefox by using an env var in one of the last comments 
[13:15] <matttbe> ogra_: oh great, thank you for that! I see the workaround!
[13:16] <matttbe> arighi: I remember I had to change this sysctl when I wanted to open vscode or something big like that a few weeks ago. I can give it a try
[13:21] <matttbe> yes, it looks like the sysctl also helps in this case, thank you both for your help!
