BADSIG, 404?

Apologies if this has been answered recently, but I'm getting several errors while trying to update. I was getting BADSIG errors, but those seem to be gone and "apt-get update" completes, but now "apt-get dist-upgrade" fails with 404s: Err http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/ubuntu/ precise/main kubuntu-default-settings-trinity all 4:3.5.13.2-0ubuntu12.04.0+0 404 Not Found etc, etc. If I put that URL into FF, I get to a mirror, so that part seems to be working. Maybe a mirror out of sync? -- Peter Laws / N5UWY National Weather Center / Network Operations Center University of Oklahoma Information Technology plaws(a)ou.edu College of Architecture, Regional and City Planning, MRCP '16 -------------------------------------------------------------------------- Feedback?
