apt-get hang at Rsyslog
Run ps afx|grep rsyslog in a different console, then:
If there are traces of rsyslogd running, probably in
<defunct>state, this is a bug in the upstart scripts incompatibility which has been fixed. Simplystop rsyslog, upgrade to the recent version (dpkg -r --ignore-depends rsyslog rsyslog && aptitude update && aptitude upgrade rsyslog).If there are no traces of rsyslogd running, and the only related process that hangs is
start rsyslog, you need to reboot (and then perhaps continue with step 1).
