Samurai server does not install on my ubuntu

Hello,
I have an Intel NUC 6CAYH (8GB), with umbrel for debian/ubuntu in 0.5.4 (because not yet available in 1.0).

I was able to install bitcoin node and electrs without problem via the app store, but when I want to install samurai server, I click on “instal”, it says “installations”, but even after 30-40 minutes nothing happens . I reload the page to see and it still says “instal”.

Thanks for reading me
