Hi, I'm unable to solve my issue installing Elasticsearch on my new Windows 11 machine running Ubuntu 20.04 (via Windows Subsystem for Linux). The log received is: ```auto Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: elasticsearch 0 upgraded, 1 newly installed, 0 to remove and 32 not upgraded. Need to get 344 MB of archives. After this operation, 552 MB of additional disk space will be used.

Welcome to our community! 😃 There's not a lot there to be honest. Is there anything in other system logs that relate to this? ---

Have a look at [this thread](https://discuss.elastic.co/t/how-do-you-configure-elasticsearch-on-ubuntu-bash-for-windows-10/194888/4) which I believe is related. ---

Thanks for the help. I read the thread Christian linked and opted for a Windows install. Straight forward, fast, and no issues. I had Elasticsearch installed and working via Ubuntu/WSL on my previous machine but that was Windows 10 and Intel. I'm now on Windows 11 with AMD and I'm not sure if this could affect things? ---
