[Owncloud] ubuntu apt-get upgrade

[Chris]

Hi Bjorn,


> ...I get the same error.

not the same. The former:

W: GPG error: http://download.opensuse.org  Release: The following
signatures couldn't be verified because the public key is not available:
NO_PUBKEY 977C43A8BA684223

error is now gone according to your pasted logs.
The other ones are from other ppas where you have to do the same.

>W: Duplicate sources.list entry
>http://download.opensuse.org/repositories/isv:ownCloud:devel/xUbuntu_12.04/

This is a new one. Just check your /etc/sources.list and /etc/sources.list.d/*
to see where you have entered this repos twice.
