@abaelter: I'm trying to reproduce the issue on Azure as that will give us an environment to investigate this bug a bit better, and I was not able to. Do you mind providing a little more information about your Azure environment?

Do you have the URN that you are running with (if you don't know this, telling us the output of `cat /etc/cloud/build.info` would be useful as well)

What instance type are you running on?

Do you mind sharing your grub configuration?

[Anders Bälter (abaelter)]

@parviafore We are using latest ubuntu 20.04 (Ubuntu 20.04.3 LTS (GNU/Linux 5.8.0-1039-azure x86_64))

URN: "Canonical:0001-com-ubuntu-server-focal:20_04-lts:20.04.202107200"

cat /etc/cloud/build.info
build_name: server
serial: 20210720

Grub config is system default.
