Error occurs during update. SOLVED

[africanlion]

Everytime i try to insall updates that have been flagged up after a search or otherwise i get this message

"W: GPG error: http://dl.google.com stable Release: The following signatures were invalid: BADSIG A040830F7FAC5991 Google, Inc. Linux Package Signing Key <linux-packages-keymaster@google.com>"

How do i solve this problem please

[bigj231]

could you post the contents of /etc/apt/sources.list ? It looks like you have a repository with a bad security key. Try removing the offending repository from that file and then reinstalling it. You can also use "Software Sources" to find and remove entries.
EDIT: also see the comments on http://www.ubuntuupdates.org/ppa/google_chrome

Thanks for your response. How do i get into /etc/apt/sources.list folder? Sorry still learning how Linux works

[bigj231]

It's actually a file, not a folder. You need to open a terminal and type in

Code: Select all

gedit /etc/apt/sources.list

Then just copy and paste everything in that file into a code box in a reply.
After you post back here with that info, I would urge you to read the following quote.

You can really break your system if you are not careful with the terminal. I would also recommend learning how to use the terminal before you start copying and pasting commands into it. It's really the fastest way to do things in Linux. Breaking things included. Like any tool, it takes time to learn how to use it.

I would strongly recommend using the Software Sources application if you are unfamiliar with the terminal.

Thanks bigj231. Will try to familiarise myslef with the terminal though its hard to know what is safe and what isnt when copying into it

Hmm, I don't see anything odd there...
Sorry, I had a brainfart. That's where all your software sources are found in Debian and older versions of Ubuntu/Mint. Look around in the "Other Software" tab in Software Sources. See if there is something similar to your error, and uncheck the box next to it. Then try updating again and see if it fixes the error. if it doesn't, recheck the box and uncheck another one.
I'll be away from the computer for the next few hours, but I'll try to assist you when I get home.

Here is a screeshot of other software

[remoulder]

post the contents of /etc/apt/sources.list

@bigj231, mint uses the inxi tool to provide system information, all repositories can be listed with inxi -r.

Thanks remoulder. I had forgotten that.
It looks like one of your Google repositories is missing a key seeing your issue from the first post. Try unchecking all of the lines that contain "google" and then running:

Code: Select all

sudo apt-get update

That should run for a bit and return no errors. If there are any errors, post back here and we'll try to work them out.

If there are no errors after you have done that, you then need to get the proper signing key. From the page I linked to earlier, the process for that is

Code: Select all

wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -

After you get the key, you can then re-enable the Google repositories and run apt-get update again.

Hi
That prblem is fixed and when i ran updates again it reported this

You have 2 broken packages on your system!

Use the "Broken" filter to locate them.

When i go to broken filters i get this

E: fgfs-base: dependency problems - leaving unconfigured
E: flightgear: dependency problems - leaving unconfigured

Sorry about this and thanks for your patience

[bigj231]

That shows me that there are 2 broken packages on your system. I would look for those two packages in Synaptic (use the search) and uninstall them or find the missing dependencies and install them. If flightgear is a 32 bit package and you are running a 64 bit system, you will need the ia32-libs(?) package. It might be easiest to uninstall flightgear then try reinstalling to get the dependencies working.
Try this line of code:

Code: Select all

sudo apt-get remove fgfs-base flightgear

That should uninstall those packages. Then post back if there are any more errors. Try looking in the documentary on flightgear's website to see the dependencies needed before reinstalling.
As an aside, I never had good performance with flightgear on any of my systems. I never uninstalled it but didn't reinstall it when I upgraded.

[bigj231]

have you tried this?

Code: Select all

sudo apt-get install -f

The -f option tells it to fix. See what you get there. Also, don't forget to update your apt-cache.
EDIT: WOHOO! 101st Post!
EDIT 2: Also try purging fgfs-base

Code: Select all

sudo apt-get purge fgfs-base

EDIT 3: remove all the fgfs packages too. There is a shortcut, but you have to be careful that it doesn't uninstall anything important. Use wildcards (*) to select all packages like fgfs-*. It saves time, but you really need to check everything before you hit okay.
4 EDITS *AH AH AH*: you can use

Code: Select all

sudo apt-get autoremove

to remove all the packages that it says it doesn't need. Do this instead of what I suggested in edits 2&3.

[africanlion]

Thanks guys its fixed. Much obliged

[bigj231]

Great. Could you edit the thread title to include [SOLVED]?
