su: Authentication failure [Partly Solved]

[Xolo]

L.S.


New Bubba owner here as of a few days.
I'm having trouble getting things to work. My first setup out of the box got stuffed up the moment I changed Bubba from dynamic to static IP, and was forced to reinstall from scratch as I couldn't get in anymore.
Now i'm on the second install, and when I log into Bubba over SSH.. and want to become root so I can get to work on installing/updating stuff, I am presented with this:

Code: Select all

xolo@bubba~$: su
Password: 
su: Authentication failure
Sorry.
xolo@bubba:~$:

So trying to get around, I tried..

Code: Select all

xolo@bubba~$: sudo
-bash: sudo: command not found
xolo@bubba~$:

None of the passwords i've tried work; the admin user for the web interface, the old default password, my user account password, a blank password, etc.

On another note, in the web interface, the 'Update' button under Settings>Update does nothing. I can click it, the page reloads, and that's it.

So i'm royally stuck. Any ideas? I must have missed something!

Thanks in advance for any ideas.

Edit: forgot the version reported on the web interface: Version 1.0.8-1
Edit 2: Resolved the su problem, I was misreading; the exact command to su is

Code: Select all

su -

Where the default password is 'excito'. I was leaving out the trailing '-', which caused the authentication failure.
How did I make this mistake? I never had to add it before on other systems, so was not accustomed to working that way.

The dash shouldn't interfer wit the authentication process, it mearly defines that we want to use a login shell. One thing that can interfer (have done that many times) is the dreadful Caps Lock key.

This is strange as now that I check for a second time after logging out, it works without the dash. and I made very sure to stay away from the caps and shift keys when typing.
But now it works as you describe (no dash), go figure

I believe I also now see the logic behind the Update button not working.
I have the Bubba connected by it's LAN port only as described in 'Scenario 6' of the online manual on the 'Network Setup Options' page.
In this situation my Bubba is unable to resolve external addresses, unlike other machines on the same switch.

I could not get the update button in the web interface working.
A manual workaround was to SSH into Bubba and issue apt-get update, apt-get distr-upgrade, then reboot Bubba.
