[Neurodebian-users] keyring package and administration directory problem

[Alex Uhlmann]

HHi there,

I've been trying to install the neurodebian-keyring package via the direct command (as for the normal command described on your website my connection always timed out), and I got the following message:

gpg: key 2649A5A9: public key "NeuroDebian Archive Key <pkg-exppsy-maintainers at lists.alioth.debian.org>" imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg:               imported: 1


When then trying to update the package, I get the following message:


W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/natty/InRelease  

W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/natty/Release.gpg  Unable to connect to extras.ubuntu.com:http:

W: Some index files failed to download. They have been ignored, or old ones used instead.
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
anne at user-desktop:~$ sudo apt-get install mricron
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

What can I do to solve the problem?

Thanks and regards,
Alex
