Aha I am viewing this on an old Ubuntu instance, I will look for how to see hidden files in Ubuntu.
I have updated the document with one more photo/screenshot of /users/ there is only one user "ha**" and then what comes up when I click on that.
There is no .bitcoin or .electrum but as you say I must figure out how to look for hidden files.
I try to view hidden files in Ubuntu by pressing Ctrl+h
But the weird thing is that when I do that it shows fewer files, not more.
So I think somehow the default, where I have posted the screenshot IS to view "all". And that when I press ctrl+h then is removes some files from view.
I do see hidden files in your new screenshot... So if there's no .bitcoin or .electrum folder, odds are there isn't one to begin with.
Is it possible you used root (eventough, within ubuntu it's hard to switch to root)? In that case, you can also check /root/ for .bitcoin or .electrum folders.
BTW, just fyi, it's your gui file manager that's hiding those hidden folders (not your os), so you'll probably have to figure out which file manager it is (i seldomly use the graphical shell, so i cannot recognize it from the screenshot) and then find a walktrough on how to view hidden files and folders for your specific file manager. Or, like i previously proposed, you can always just use a terminal (which i personally find much easyer to use, but that's probably personal taste).
