Install failure of Sonarqube scanner extension for azure devops 2020

I am trying to install the extension to an on-prems Azure Devops 2020 for an on-prems Sonarqube 8.6

When trying via VS marketplace i get these errors:
We’ve encountered an error while downloading the extension. Please try again later.
Permission section could not be loaded.

When trying manually by vsix file i get:
The extension package size ‘29585246 bytes’ exceeds the maximum package size ‘26214400 bytes’

The extension version i can get is 5.0.0 but the description “New Major Version for Azure Devops 2019 only, that resolves issues with LetsEncrypt Certs. For TFS2017/2018 use version 4.23.1” tells med that I should not use 5.0.0, but not what I should use for 2020, and when I try “show other versions” it only gives me the same url for all of them, getting v5.0.0.
When trying via the more applicable docs 8.6 I get the same url.

Same Error for me too,
Trying to install Sonarqube extension from Azure Devops 2019.

We’ve encountered an error while downloading the extension. Please try again later. Permission section could not be loaded.

Hi @Zer0ne, @Manojkumar_Thangadur,

You can download earlier versions of the Azure DevOps plugin from here and if you’re specifically looking for 4.23.1 it’s here.

You might also want to check out this earlier thread about changes in Node requirements from 4.22 to 4.23.

Regards,
