Though the system doesn't boot, running bash chrooted to it worked. Using that method, I tried what you suggested in an earlier message: > could you please try running dpkg -i on the modules-init-tools > package in /var/cache/apt/archives I assume you mean module-init-tools. There were two such packages: -r--r--r-- 1 root root 86570 2007-08-20 16:21 module-init-tools_3.3-pre3-1ubuntu7_i386.deb -rw-r--r-- 1 root root 87414 2007-10-05 20:04 module-init-tools_3.3-pre4-2ubuntu4_i386.deb I chose the latter one. This is what happened: [EMAIL PROTECTED]:/var/cache/apt/archives# dpkg -i module-init-tools_3.3-pre4-2ubuntu4_i386.deb (Reading database ... 36359 files and directories currently installed.) Preparing to replace module-init-tools 3.3-pre4-2ubuntu4 (using module-init-tools_3.3-pre4-2ubuntu4_i386.deb) ... Unpacking replacement module-init-tools ... Setting up module-init-tools (3.3-pre4-2ubuntu4) ... Segmentation fault (core dumped) dpkg: error processing module-init-tools (--install): subprocess post-installation script returned error exit status 139 Errors were encountered while processing: module-init-tools Rerunning dpkg under "strace -f" revealed that the core dump is from /usr/sbin/update-rc.d. I located the core file in /etc/rc0.d/core. Running "/usr/sbin/update-rc.d module-init-tools start 15 S ." by hand also causes a core dump. I will attach the part of the strace -f output pertaining to the /usr/sbin/update-rc.d process. Since /usr/sbin/update-rc.d is a perl script, I note that the installed version of perl is 5.8.8-7ubuntu3.1 according to dpkg-query --show. -- Server upgrade from 7.04 to 7.10 fails https://bugs.launchpad.net/bugs/187316 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
