Getting error:
[SSH] connection failed, retrying in 30 seconds (#<Net::SSH::AuthenticationFailed: Authentication failed for user ubuntu@>)
Is Ubuntu-22 supported??

what version of test-kitchen and kitchen-azure are you running? Can you also see which net-ssh gem version you have. Version below 7.x doesn't support the newer ssh algorithms newer servers are supporting and they dropped support for the default rsa keys with less than 1024 bits.

[alpana17]

Using
test-kitchen 2.7.2
kitchen-azurerm 1.4.0
net-ssh 6.1.0

Please suggest

you'll need to upgrade your gems to fix your issues.
