I also experienced this issue. It causes me problems in my project. I discuss the issue here: http://github.com/borisdaeppen/NaYaBoh/issues/#issue/33
What I have found out: ---------- adzapper has squid as a dependency. If you don't have squid installed, and then install adzapper so that squid is installed automatically - everything goes fine. BUT: if you install the squid package first and then afterwards install the adzapper package the installation fails with the following error messages: No apport report written because MaxReports is reached already E: Sub-process /usr/bin/dpkg returned an error code (1) A package failed to install. Trying to recover: invoke-rc.d: unknown initscript, /etc/init.d/squid not found. dpkg: error processing adzapper (--configure): subprocess installed post-installation script returned error exit status 100 Errors were encountered while processing: adzapper ---------- Would be nice if the problem is solved, cause it makes that my project's installation fails. Maybe I can "solve" the problem when I exchange the position of adzapper and squid in my dependencies-list so that adzapper comes first... -- package adzapper 20090301-1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 100 https://bugs.launchpad.net/bugs/658700 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
