As explained in http://www.debian.org/doc/debian-policy/ch- controlfields.html#s-f-Source and reported correctly by aptdaemon xplanetFX is not a valid package name.
"Package names (both source and binary, see Package, Section 5.6.7) must consist only of lower case letters (a-z), digits (0-9), plus (+) and minus (-) signs, and periods (.). They must be at least two characters long and must start with an alphanumeric character." I'm closing this report because it is not a bug with Ubuntu, the package is not from an official Ubuntu repository and should be reported to the maintainer of the package. ** Changed in: update-manager (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/759501 Title: update-manager crashed with AptDaemonError in commit(): org.debian.apt: xplanetFX isn't a valid package name -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
