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

### 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?
