Public bug reported: I upgraded a VPS from Ubuntu 14.04 LTS to 16.04 LTS. During the upgrade the libc6 preinst script showed this error:
Checking for services that may need to be restarted... Checking init scripts... /var/lib/dpkg/tmp.ci/preinst: 355: /var/lib/dpkg/tmp.ci/preinst: runlevel: not found Then the upgrade process hung for, I think, unrelated reasons. /sbin/runlevel is part of the 'upstart' package in 14.04, but it was moved to systemd-sysv in 16.05. At this point in the upgrade upstart already upgraded to the xenial version, but systemd-sysv wasn't yet installed. --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 CrashDB: ubuntu DistroRelease: Ubuntu 16.04 Package: ubuntu-release-upgrader (not installed) ProcEnviron: LC_CTYPE=lt_LT.UTF-8 TERM=xterm-256color PATH=(custom, no user) LANG=lt_LT.UTF-8 SHELL=/bin/bash Tags: xenial dist-upgrade Uname: Linux 2.6.32-042stab116.2 x86_64 UpgradeStatus: Upgraded to xenial on 2016-09-18 (0 days ago) UserGroups: _MarkForUpload: True ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New ** Tags: apport-collected dist-upgrade xenial ** Also affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New ** No longer affects: atop (Ubuntu) ** Tags added: apport-collected dist-upgrade xenial ** Description changed: I upgraded a VPS from Ubuntu 14.04 LTS to 16.04 LTS.
