Dear Maintainer, While upgrading to jessie, update-rc.d failed and stopped apt-get Found out update-rc.d call from /var/lib/dpkg/info/plymouth.postinst failed. Changed the file to this while updating diff plymouth.postinst_orig plymouth.postinst_fix 34c34 < update-rc.d plymouth start . 2 3 4 5 . stop . 0 6 . >/dev/null || exit $? --- 39c39 < update-rc.d plymouth-log start . S . >/dev/null || exit $? --- After update and reboot I could revert the file. I suspect this is a dependency issue in the upgrade Best regards Torben
