Microsoft Azure customers running Canonical's Ubuntu 18.04 (aka Bionic Beaver) in the cloud have seen their applications fail after a flawed security update to systemd broke DNS queries.

The situation is as odd as it sounds: if you're running Ubuntu 18.04 in an Azure virtual machine, and you installed the systemd 237-3ubuntu10.54 security update, you've probably found yourself unable to use DNS within the VM, which causes applications and other software relying on domain-name look-ups to stop working properly.

"Starting at approximately 06:00 UTC on 30 Aug 2022, a number of customers running Ubuntu 18.04 (bionic) VMs recently upgraded to systemd version 237-3ubuntu10.54 reported experiencing DNS errors when trying to access their resources," an update to the Microsoft Azure status page said on Tuesday.
