404 updating sources

I’ve tried getting rid of the gb. in favour of http://archive etc. Same problem.

I can probably live without multiverse, but main seems pretty basic and essential.

Is anyone else seeing any software source problems on Mate 17.10 for the pi?

Do I have to delete my apt cache and start over?

Any hints or suggestions?

Thanks

armhf is stored at ports.ubuntu.com

If the sources you’ve quoted have come from an upgrade, then that is a bug that needs reporting.

Thanks. I’ve fixed that now.

And TBH I have no idea where the sources came from; they were gb. so possibly when I tried to switch over to UK mirrors, but I couldn’t say for sure.
