this may help a bit more but it doesn`t make sense!
The original TarGZ thing that went into the Download drawer Has all the Bitcoin-qt and many other files, but I didn`t see an Install thing anywhere so I ignored it.
Then I tried the Snap thingd and that Did install and gave me a bitcoin logo that I clicked on and got Bitcoind working.
the directory path for that is: Home/snap/bitcoin-core/common/.bitcoin
But... there`s no bitcoind file in there? and yet it`s clearly running? I had to click show hidden files to see most of these things too, but bitcoind doesn`t seem to be in there, but it must be?
so I`m even more confused now! LOL
