My friend has just come up with a problem connected to a routine update.
He is running Ubuntu 12.04 and he got the message saying that there were several updates to download.
So he clicked the button to do so and a message came up saying that "python-lockfile" was one of these and "The action would require installation of packages from unauthenticated sources"
So he asked me what I knew of this.
As will be obvious from my previous postings the answer had to be, " Well nothing really, but we need some advice from the experts. It looks to have a potential for trouble."
So please can someone shed some light on this.
I have looked on the internet and found one or two references to "python-lockfile", but they were all way up above my head.
Many thanks in advance.

It looks like he may have added an unsigned PPA (or one with an expired key) to his sources list.

Thank you for your reply, nelz.
Am I right in assuming that you are referring to the list of "Trusted Software Providers" listed under the "Authentication" button of "Update Manager"?
We both have identical lists and I am experiencing no problem.

Whilst ferreting about on t'internet today for "inspiration" I came across this:-
Run the command directly from the terminal emulator of your choice (personally, and as an example, I use Konsole). The command is sudo apt-get upgrade OR sudo apt-get dist-upgrade. Run man apt-get for more information.
I was a bit wary of this because of the word "upgrade" rather than "update".
I do not think my friend wants to leap into 14.04 yet (and certainly I don't).

update gets a fresh list of available packages, upgrade downloads and installs the latest version of packages for your chosen distro, while dist-upgrade gets packages that ordinary upgrade doesn't handle, like new kernel versions.

dist-upgrade can also upgrade you to a newer version of your distro if you change the sources to a those needed for a new version.

So you can use all three commands with impunity (unless there are any warnings which spring up to advise you to the contrary), indeed, you need to run update first anyway.

Thanks for that elucidation, Rhakios.
I shall have to see what happens when we try it out tomorrow.
