I've been running Ubuntu 10.04 (Lucid) 64-bit for about one year now. Everything still seems to be working properly, but for the last two months, I've been getting this error message every time Update Manager runs:
"Failed to fetch http://ppa.launchpad.net/sevenmachines/flash/ubuntu/dists/lucid/main/binary-amd64/Packages.gz 404 Not Found Some index files failed to download, they have been ignored, or old ones used instead."
I did a bit of searching, and the best I can find is that Sevenmachines isn't supporting this software anymore and has deleted everything relating to it. I haven't been able to find anything discussing a new version or even how to get Synaptic/Update to stop looking for updates to this software. Most of what I've found dates to mid 2010 and is no longer current (in fact, most of what I've found is how to install the Sevenmachines version).
Should I keep running version
126.96.36.199-0ubuntu0~sevenmachines1? If yes, how do I get Synaptic to stop looking for updates that no longer exist? If not, what software should I be installing to replace it and still keep Flash working?
