Cannot update Linux Mint

Hi

I have just gone to update Linux Mint 13 but am getting the following error message:

: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://security.ubuntu.com precise-security Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>

Is anyone able to help please?

Many thanks

Does Mint 13 still gets updates?

[Cosmo.]

Yes, for the next 9 months.

[wmh]

Oh, that's nice! Then his/her problems can be fixed.

Yes, for the next 9 months.

Thanks all!

Out of interest, would I be able to alter anything so I can get updates in 9 months time, even if it's not officially supported? I love the system I have

[Moem]

As far as I know, that's a No, sorry. The only way is up(grade).

[kylerickards]

Ok, thank you - I take it upgrading in place isn't an option?

[Moem]

13 to 17.x?
I'm afraid that's another big Nope. I'm sorry I don't have better news!

In the future, create separate partitions for / and /home, that way you can keep all your files and program settings if you decide you want to reinstall/upgrade mint.

Many thanks.

I can easily back up personal files and folders but is there a way of migrating the programs across when I upgrade or do I just need to remember what I've installed or write a list?

Sorry for all the questions.

You can use Backup Tool (should already be installed) to backup your software selection. This will only backup software downloaded from repositories though, not software downloaded from a third party.

[Cosmo.]

Note, that the programs, that you installed in an old system, are written just for this old system. With a new system you will probably need program versions for the new system. In case, that you installed the programs from the official repositories, this is no problem; you will get offered the matching program versions. If you have programs from other sources, you have to check, if versions for the new OS are available.
