It's not a question but I think it can be useful ...
While dist-upgrading a saucy custom DVD, I've got an error about whoopsie:
invoke-rc.d: unknown initscript, /etc/init.d/whoopsie not found. dpkg: error processing /var/cache/apt/archives/whoopsie_0.2.24.1ubuntu1_i386.deb (--unpack): subprocess new pre-removal script returned error exit status 100 invoke-rc.d: unknown initscript, /etc/init.d/whoopsie not found. ... Errors were encountered while processing: /var/cache/apt/archives/whoopsie_0.2.24.1ubuntu1_i386.deb E: Sub-process /usr/bin/dpkg returned an error code (1)
Investigating a little, I've found that on my other pc, running precise, /etc/init.d/whoopsie, was a symlink:
whoopsie -> /lib/init/upstart-job*
while in chrooted saucy looking for /etc/init.d/whoopsie I've got cannot access /etc/init.d/whoopsie: No such file or directory
So I've created the above symlink and finally dist-upgrade worked fine.
