This bug still seems to exist (25/1/2015). Apologies if this is the wrong place to post this: just installed Edubuntu 14.04 (on 25/1/2015), let it install the updates.
Now I am trying to use Google Chrome (yuck; version 40.02214.91) in Guest mode. The error "Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted" pops up. Running /opt/google/chrome/google-chrome Cx -> chromium displays the same error. Appending the flag --no-sandbox works but that pops up a warning in Chrome which I'd like to suppress (there's no point to the warning since Chrome, with that flag, will be running in the Guest login which gets wiped after each logout). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1298021 Title: Google Chrome (not chromium) won't start in guest session Status in lightdm package in Ubuntu: Fix Released Bug description: Related, but not a dupe of bug 577919 Install Google Chrome (not chromium) and switch to a guest session Start chrome from a terminal See the following error:- "Failed to move to new PID namespace: Operation not permitted" I see these apparmor denials:- [Tue Mar 25 12:51:46 2014] type=1400 audit(1395861131.882:541): apparmor="DENIED" operation="capable" profile="/usr/lib/lightdm/lightdm-guest-session" pid=30034 comm="chrome-sandbox" capability=21 capname="sys_admin" [Tue Mar 25 12:52:13 2014] type=1400 audit(1395861159.510:542): apparmor="DENIED" operation="open" profile="/usr/lib/lightdm/lightdm-guest-session" name="/proc/30062/oom_score_adj" pid=30062 comm="chrome" requested_mask="wc" denied_mask="wc" fsuid=130 ouid=130 ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: lightdm 1.9.13-0ubuntu1 ProcVersionSignature: Ubuntu 3.13.0-19.40-generic 3.13.6 Uname: Linux 3.13.0-19-generic x86_64 ApportVersion: 2.13.3-0ubuntu1 Architecture: amd64 CurrentDesktop: Unity Date: Wed Mar 26 19:08:04 2014 EcryptfsInUse: Yes InstallationDate: Installed on 2012-06-29 (634 days ago) InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120425) SourcePackage: lightdm UpgradeStatus: Upgraded to trusty on 2014-01-20 (65 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1298021/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
