I just got the very same bug on today's ppc image. The backtrace says it all, this just seems to be a typo: it should be syslog.LOG_WARNING, not syslog.LOG_WARN.
Bumping importance since this seems to affect all platforms and many people. ** Changed in: ubiquity (Ubuntu) Importance: Medium => High Status: Needs Info => Confirmed ** Summary changed: - Crash in installation on amd64 laptop + Crash in installation on amd64 laptop (syslog.LOG_WARN undefined) -- Crash in installation on amd64 laptop (syslog.LOG_WARN undefined) https://launchpad.net/bugs/59257 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
