Title: linux-gcp 6.8.0-1005.5 (+ others) Noble kernel regression iwth new apparmor profiles/features Status in chrony package in Ubuntu: New Status in linux package in Ubuntu: New Status in linux-aws package in Ubuntu: New Status in linux-azure package in Ubuntu: New Status in linux-gcp package in Ubuntu: New Status in linux-ibm package in Ubuntu: New Status in linux-oracle package in Ubuntu: New Status in snapd package in Ubuntu: New Status in chrony source package in Noble: New Status in linux source package in Noble: New Status in linux-aws source package in Noble: New Status in linux-azure source package in Noble: New Status in linux-gcp source package in Noble: New Status in linux-ibm source package in Noble: New Status in linux-oracle source package in Noble: New Status in snapd source package in Noble: New Bug description: * Canonical Public Cloud discovered that `chronyc -c sources` now fails with `506 Cannot talk to daemon` with the latest kernels. We are seeing this in linux-azure and linux-gcp kernels (6.8.0-1005.5) * Disabling AppArmor (`sudo systemctl stop apparmor`) completely results in no regression and `chronyc -c sources` returns as expected * Disabling the apparmor profile for `chronyd` only results in no regression and `chronyc -c sources` returns as expected * There are zero entries in dmesg when this occurs * There are zero entries in dmesg when this occurs if the apparmor profile for `chronyd` is placed in complain mode instead of enforce mode * We changed the time server from the internal GCP metadata.google.internal to the ubuntu time server ntp.ubuntu.com with no change in behaviour We also noted issues with DNS resolution in snaps like `google-cloud-cli` in GCE images. * Disabling apparmor completely for snaps too (`sudo systemctl stop snapd.apparmor`) results in no regression and calling the snaps returns as expected. The same issues are present in azure kernel `linux-azure` `6.8.0-1005.5` and the -proposed `6.8.0-25.25` generic kernel.
