Public bug reported: Binary package hint: flex
When I install 'flex' 2.5.35-2ubuntu1 on Intrepid Ibex 8.10 (or 'bison- doc' by the way), the installation stops with the error message: E: flex: subprocess post-installation script returned error exit status 1 Nevertheless 'flex' is installed correctly. The detailed installation protocol reveals, that the error occurs when 'install-info' tries to append the corresponding info-document to the info tree: Selecting previously deselected package flex. (Reading database ... 214614 files and directories currently installed.) Unpacking flex (from .../flex_2.5.35-2ubuntu1_i386.deb) ... Processing triggers for man-db ... Setting up flex (2.5.35-2ubuntu1) ... install-info: No dir file specified; try --help for more information. dpkg: error processing flex (--configure): subprocess post-installation script returned error exit status 1 Errors were encountered while processing: flex E: Sub-process /usr/bin/dpkg returned an error code (1) A package failed to install. Trying to recover: Setting up flex (2.5.35-2ubuntu1) ... install-info: No dir file specified; try --help for more information. dpkg: error processing flex (--configure): subprocess post-installation script returned error exit status 1 The reason for this is a wrong parameter set for 'install-info'. If you have a look at /var/lib/dpkg/info/flex.postinst you will find the line: install-info --quiet --section "Development" "Development" \ --description="A fast scanner generator" /usr/share/info/flex.info The correct synopsis is: install-info [option]... [info-file [dir-file]] But if 'info-file' or 'dir-file' are not specified, you have to define them with the respective options. So, the correct 'install-info' command must look like this: install-info --quiet --section "Development" "Development" \ --description="A fast scanner generator" /usr/share/info/flex.info /usr/share/info/dir If you correct this and call: sudo apt-get upgrade afterwards, the error will disappear. ** Affects: flex (Ubuntu) Importance: Undecided Status: New -- post-installation script error https://bugs.launchpad.net/bugs/305505 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
