I see that Bitcoin Core 23.0 is available on the link at the top of the forum. There are several versions of Linux for download. Which one do we use for the FutureBit?
1. Linux (tgz)
2. ARM Linux (64 bit - 32 bit)
3. RISC-V Linux (64 bit)
4. PPC64 Linux (64 bit - 64 bit LE)
To install do I then just copy all the files to the appropriate directories on the FutureBit and restart?
The Futurebit Apollo BTC has an OrangePi 4, which is a 64-bit ARM CPU. So this would be option 2.
However, I don't think on Futurebit OS it is installed in the default location.
You can check with
locate bitcoin-cli and
locate bitcoind, as well as checking the version before and after upgrading with
bitcoind --version
