Basically apt-get is complaining about timeouts when I try to update packages & I noticed it was coming from a few repos in particular (I think the ones that have been shut down - repo.pub.meego.com or rzr??). I have installed Inception & have found that some of my packages, namely the systemui one, are outdated when it tries to download the update.

I don't know how to use Nano to edit the list file to delete the old repos (though what should they be replaced with?).

Thanks

Navigate into /etc/apt/sources.list.d directory and delete list files of repositories that no longer work.

After doing that, run apt-get update.

and which repositories to replace them with?

Can someone please provide a guide how to remove repo.pub.meego??

Vi is not opening the 'sources.list.d'

what is the osa.list?how to remove?

sources.list.d is a directory, so I doubt you'll be able to open it with any editor.
Do you want just to remove the repo.pub.meego repositories or change them to skeiron.org where they have been rehosted?

If you want to just go to the default configuration, open a terminal on the device, run devel-su to become root and type "ls /etc/apt/sources.list.d". You will see a few filenames.
Keep a file whose name begin for "aegis-ssu-keyring" (endpart depends on your N9 variant, and the file "osa.list" (this is Ovi/Nokia Store).
Rests are additional repositories, and to go back to original device configuration you can delete them.

If instead you want to convert the old repo.pub.meego.com repositories to their rehosted copies on skeiron, you can run this command:

osa.list is used to access Ovi Store. Are you sure you want to remove it and lose access to it?

for shared repo

I do not want to delete it.I wanted to know what they are used.thanks.

Surely you'd want sources.list.d there?
