Use btc blockchain on ubuntu from umbrel

I’ve been running bitcoin node on my umbrel for the past couple of months. But I have been unable to access my umbrel for the past couple of weeks for some reason. This has happened before as well and I reinstalled umbrel and re-downloaded the whole blockchain one more time. But I don’t want to do that again.
I am thinking of running bitcoin node on ubuntu but don’t want to re-download the blockchain. Is there a guide on how I can use the existing blockchain data on external SSD used for running bitcoin node on umbrel on Ubuntu?
If there’s someone else out there who has done such before please help out.

Here’s a great guide! Please let me know if you have any questions or require any assistance

Isn’t this for running a new node on umbrel instead of running on any other distro?

Both methods should work for you.

Technically you only need the first 3-4 instructions of method 1 for your new node, and then you can point core to that directory.
