Public bug reported: Binary package hint: graphviz-cairo
Basically, trying to install the graphviz-cairo plugin to graphvis using apt-get results in two shell script files sticking around in /var/lib/dpkg/info/ that apt-get keeps trying to run, so apt-get can't install, remove, or update anything until the two script files are deleted manually. I'm running Edgy, but I encountered this bug a year ago on Dapper beta and didn't report it. The fix is easy, but it's affected several people and come up at least three times on the forums: http://ubuntuforums.org/showthread.php?p=2117662 http://www.ubuntuforums.org/showthread.php?t=365719 http://ubuntuforums.org/showthread.php?p=2190896 repro steps: >sudo apt-get install graphviz-cairo it should end like this: Setting up graphviz-cairo (2.8-2) ... /var/lib/dpkg/info/graphviz-cairo.postinst: 11: dot: not found dpkg: error processing graphviz-cairo (--configure): subprocess post-installation script returned error exit status 127 Errors were encountered while processing: graphviz-cairo E: Sub-process /usr/bin/dpkg returned an error code (1) now, try using apt-get for just about anything else: >sudo apt-get remove evolution ...

The problem seems to me to be two script files, /var/lib/dpkg/info/graphviz-cairo.postinst and /var/lib/dpkg/info/graphviz-cairo.postrm I know almost nothing about shell scripting, but they seem very broken. This is graphviz-cairo.postinst: (some spaces removed) #!/bin/sh set -e case "$1" in configure) dot -c ;; esac exit 0 and graphviz-cairo.postrm is almost identical: >diff /var/lib/dpkg/info/graphviz-cairo.post* 8,9c8,9 < configure) < dot -c --- > remove) > dot -c I have no experience with this, but this seems like a somewhat serious bug that should also be (relatively) quite easy to fix. ** Affects: graphviz-cairo (Ubuntu) Importance: Undecided Status: Unconfirmed -- installing graphviz-cairo breaks apt-get until script files are manually deleted https://launchpad.net/bugs/86914 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
