Need to Verify Signing Keys - How To

[Rick St. George]

Curious and need to know ... Are UbuntuStudio signing keys the same as Ubuntu? Or Xubuntu?

Need to verify that a friend has the correct signing keys before doing updates. How can we do this in v16.04?
I ran the following - and even though I running UbuntuStudio it shows Ubuntu. Makes me question - is this normal?
He has Xubuntu. So how can a person find out???

lsb_release -d
Description:    Ubuntu 16.04.3 LTS

Thanks!

Noticed a recent update for Software Updater when running a recent update. Now I get this ...

"failed to download repository information" in UbuntuStudio v16.04. After looking at the Tabs, everything seems OK. Close it and then it shows "Software on this computer is up to date". What ?!?!?!? Here is a print of code I ran.

~$ cat /etc/apt/sources.list

Nothing seems out of place! What do you think?

Thanks!

Could you post the results of

sudo apt update

so we can see if there might be more detailed clues there?

Will you show us the error with:

sudo apt update

HA! Ninja'ed by QIII

Ahhh !!!

Now ... What to do about it?

Fade 3 and Punt! (Joke)
Lets see how this Looks:

nano /etc/resolv.conf

Paste back please. This could be a cumbersome process so don't get frustrated.

archive.ubuntustudio.org does not appear to exist.

How did that come to be in your sources list?

I suppose it should be there ... I'm running UbuntuStudio v16.04 I thought!?!

Allrighty then.
And I have you tried switching to another or main server for your sources? https://help.ubuntu.com/community/Repositories/Ubuntu
