Can anyone help me with setting up MN issue.

My trouble is on local side (Ubuntu).

For some reason, darkcoind / darkcoin getinfo only runs after i sudo su - . . .
But that gave version as 91001, blocks were correct.
Then I exit su, cd ~/.darkcoin/ , and wget http://www.darkcoin.io/downloads/rc/darkcoind
Now, I can only run darkcoind + commands in su and still on version 91001.
When I try run darkcoind from regular user, I get :
Error: failed to read block
Error: failed to connect to best block

Any idea what I'm doing wrong?
Any help is appreciated
