Description

AADSSHLoginForLinux VM extension deployment fails on Oracle Linux images.

Current behavior

Using Azure Portal, adding "Azure AD based SSH Login" extension to Oracle Linux image based VM, fails with error message:

The handler for VM extension type 'Microsoft.Azure.ActiveDirectory.AADSSHLoginForLinux' has reported terminal failure for VM extension 'AADSSHLogin' with error message: '[ExtensionOperationError] Non-zero exit code: 20, /var/lib/waagent/Microsoft.Azure.ActiveDirectory.AADSSHLoginForLinux-1.0.2385.1/./installer.sh install

Additional information

Temporary workaround is editing installer script line 316 manually and re-running in VM. Issue appears to be in Frontdoor config of https://packages.microsoft.com/ol - instead of expected response HTTP 404 (not found) it responds with HTTP 403 (forbidden).
Possibly a duplicate of issue 1875.
