So this happens when perl/perl-modules are unpacked, but not configured yet, and then some dpkg trigger pokes doc-base.
I tried various scenarios with having perl 5.14 unpacked but not configured, and then unpacking, triggering and/or installing doc-base and/or nano. I do get the symbol lookup error plenty of times, but always with ******************************************************************* It seems install-docs is not fully functional at the moment, and it will try to recover from the error next time it is called. Please run `install-docs --install-changed' command manually after the upgrade process is finished. "******************************************************************* and the exit code is 0. But right now I can't make too much sense of the log anyway: Processing triggers for doc-base ... /usr/bin/perl: symbol lookup error: /usr/lib/perl5/auto/UUID/UUID.so: undefined symbol: Perl_xs_apiversion_bootcheck dpkg: error processing doc-base (--unpack): subprocess installed post-installation script returned error exit status 127 Errors were encountered while processing: doc-base The context shows that at that time perl* are at 5.14/unpacked, but doc- base hasn't been touched anywhere yet. It never said "unpacking doc-base ..." for example, so the "dpkg: error processing doc-base (--unpack)" doesn't make sense, especially since unpack doesn't run postinst scripts. Was this an upgrade from oneiric, or an intra-precise upgrade? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/897880 Title: package doc-base 0.10.3 failed to install/upgrade: ErrorMessage: subprocess installed post-installation script returned error exit status 127 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/doc-base/+bug/897880/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
