Package: dpkg Version: 1.18.24 Severity: important Hi,

Errors were encountered while processing: /tmp/apt-dpkg-install-1LEpM7/47-texlive-base_2017.20170818-1_all.deb My interpretation: I think it's 'wims.prerm deconfigure' failing. Then we get the message about texlive-base_2017.20170818-1_all.deb (--unpack) failing. Then we get the message about installed pre-removal script returned error exit status 1 (which would be wims.prerm) Thereafter 'wims.prerm failed-upgrade' is run Thereafter 'texlive-base.prerm failed-upgrade' is run BTW, there isn't a command line switch to manually deconfigure a package with dpkg, is there? That would allow easier testing how deconfigure fails ... And I would try with piuparts to deconfigure every single package in the archive :-) Andreas
