Azure CLI ignores locally installed azcopy if version is 10.31.0~preview.1

[tsvietOK]

Describe the bug

I have installed Azure CLI 2.71.0 and azcopy 10.31.0~preview.1. When I run the sync command I see Azure CLI ignores locally installed azcopy with version 10.31.0~preview.1 and downloads the old one 10.13, which doesn't have argument --compare-hash.

Related command

az storage blob sync `
            -c $Container `
            -s $workDir `
            --account-name $StorageAccountName `
            --auth-mode login `
            -d "$dir/" `
            -- --compare-hash MD5

Issue script & Debug output

Looks like the used "packaging.version" package used in this code block doesn't support this version format 10.31.0~preview.1:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/packaging/version.py", line 54, in parse
    return Version(version)
           ^^^^^^^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/packaging/version.py", line 200, in __init__
    raise InvalidVersion(f"Invalid version: '{version}'")
packaging.version.InvalidVersion: Invalid version: '10.31.0~preview.1'

Expected behavior

Version (even preview) is correctly resolved, and locally installed azcopy is used instead of downloading the new one (older version).

Hi @tsvietOK,

This is not the official Azure CLI published by Microsoft.

How to tell if the installed Azure CLI is unofficial:

• Unofficial Azure CLI deb packages are distributed by Linux repositories #19640 (comment)
• Unofficial Azure CLI deb packages are distributed by Linux repositories #19640 (comment)

Please follow https://learn.microsoft.com/en-us/cli/azure/install-azure-cli-linux to install Microsoft official Azure CLI.
