Update Manager help

It seems you are using debian sources which usually does not work in Ubuntu. Can you paste the output of

more /etc/apt/sources.list

Ah, and you need to add some keys: check the website of your sources, e.g. packages.medibuntu.org, and look for a public key. Then follow the procedures here:

Hi Bernhard. Thank you for answering.

I think I downloaded add ons for Mplayer from medibuntuto make it work for video.

I have
Under Applications-Other-Import Key
But it doesn't do anything

Have installed Firefox add ons Launchpad but cant see it anywhere and don't know what it does.

System-Administration-Software Sources-Tab Authentication has an import key button but dont understand it.

Visited packages.medibuntu.org but could find no reference to keys- Just packages.

Visited https://help.launchpad.net/Packaging/PPA#Adding%20a%20PPA%20to%20your%20Ubuntu%20repositories but it seems to say that i need to know the url for the key?????

Installed Skype-2 for Linux 6 days ago and finally have it working. Used Skype-debian_2.0.0.72_1 i386.deb as I could not find it under Applications Add/Remove

This is the outcome of
more /etc/apt/sources.list

nigel@Moose:~$ more /etc/apt/sources.list

(not certain if I should be answering this way or from my email???

Yes, you need a key from the site where you are downloading the packages from. Let me check...

And btw, you only pasted half of your sources.list :)

medibuntu key: packages.medibuntu.org/medibuntu-key.gpg
then go to "System" "Administration" "Software Sources" then "Authentication" tab and "import key".

debian keys: never did it myself, but you should find the answer here
http://wiki.debian.org/SecureApt

Thanks Bernhard, that solved my question.

I noticed that but waited 5 mins and assume it was all done,

The problem has gone and I thank you Bernhard.

Do you know of a place with a list of basic Terminal commands that all newbies should know with a description of what they do. I have all sorts of problems understanding whats happening and lists of syntax are not very helpful.

Again thank you

Regards

Nigel

Well, you can always google individual commands, how about this?

https://help.ubuntu.com/community/UsingTheTerminal

or if you actually want to write bash scripts (small terminal executables)

http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html

And you can get some help on the command line itself by typing "--help" or sometimes "-h" after a command - that's a standard linux thing in all distros apparently. For example try typing

sudo --help

or

ls --help

probably not very good examples but i'm sure you can find better ones. Another thing is that when you're typing on the command line keep tapping the Tab key occasionally and watch it complete commands and pathnames in a very "predicative texting" type of way except it's good at staying relevant. Double tapping the Tab key can be revealing too.

Good luck and regards from
Tom :)

Oh and the up-arrow is great too. The thing i find weird is that CtrlV wont paste but mouse paste works.

Thank you both. Most interesting

You're welcome, thanks :)
Actually i just love the chance to show off command-line features and use the phrase "mouse paste" rofls, i'm not sure why but it always makes me chuckle ;)

Have fun, regards from
Tom :)
