[BUG] Backup not possible from Azure Portal with waagent + Ubuntu 24.04 LTS

[pthoelken]

Describe the bug:

Since the update from Ubuntu 20.04 LTS to 24.04 LTS ( 20.04 LTS -> 22.04 LTS -> 23.04 -> 24.04 LTS, normal procedure) I've got daily the message from the Azure monitoring portal, that the backup was unsucessful. After checking the log files, I've got the error message from below while the agent try to create the snapshot.

Distro and WALinuxAgent details:

• Distro and Version: Ubuntu 24.04 LTS (upgraded from 20.04 LTS, see above)
• WALinuxAgent version Informations

WALinuxAgent-2.9.1.1 running on ubuntu 24.04
Python: 3.12.3

@pthoelken This is an issue on the backup extension, rather than on WALinuxAgent. Could you report this issue on https://github.com/Azure/azure-linux-extensions?
