I had upgraded to ubuntu 8.04 (architecture i386) from 7.10 recently. When I check for updates, I get the following error:
Not All Updates Can Be Installed
Run a partial upgrade to install as many updates as possible.
This can be caused by:
- A previous upgrade which didn't complete.
- Problems with some of the installed software.
- Unofficial software packages not provided by ubuntu.
- Normal changes of pre-release version of ubuntu.
In the process of trying to update, I also get the following error:
W: GPG error: http://ftp.de.debian.org sid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A70DAF536070D3A1
Could this particular error have anything to do with Deluge? I'm not able to bring up Deluge on my computer, by the way.
I want to be able to update my computer withour any errors. I don't want to partially update it, I want to completely update it without seeing any of these errors. How do I fix this?
