Pihole stuck on installing

Hello everyone,
i have an issue installing pihole.
I am running Umbrel for months now and it is up to date.
also installed mempool and BTC pay server for testing purpose successfully but it seems that Pihole is stuck on installing indefinitely.
When i press refresh after 10 minutes , it’s like nothing happened and i can still click on Install.
Config is on a VM :
Ubuntu 20.04.3 LTS

Thanks for the help
