Azure CLI version 2.38.0-1~focal install failure though being an available version

[KishoreKarthickC]

Describe the bug

az-cli version 2.38.0-1~focal has been listed an available version, but the install is failing below:

sudo apt install -y --allow-downgrades azure-cli=2.38.0-1~focal
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package azure-cli is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Version '2.38.0-1~focal' for 'azure-cli' was not found

This issue is happening intermittently as it is succeeding in some instances and failing at some instances. Can we get a RCA on this issue?

Hi @KishoreKarthickC,

2.54.0 is not the latest Azure CLI(2.55.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

Thank you for opening this issue, we will look into it.

The information you've provided is conflicting.
If you can see 2.38.0-1~focal in apt policy azure-cli, Package azure-cli is not available should not show up.
Please provide the output of apt update and apt-cache policy azure-cli
