Package: aptitude Version: 0.8.8-1 Severity: normal (state bundle available on request, too big to attach anyway)
>From this situation, first mark texlive-htmlxml for downgrade to stable, then enter resolver, and refuse all choices from first 2 screens to get to the third one, which proposes to remove 17 packages and downgrade 12 to stable. The goal is to downgrade to stable rather than removing. sequence 1: * refuse all removal choices but texlive-plain-generic which did not exist in stable * next state proposes only the removal of that new package, and downgrade of all others - cool this is what I wanted Note we can also do things incrementally by marking one package at a time for removal: this all work until I get to refuse removal of texlive-plain-generic (obviously, first time you get here it was not obvious you could not refuse it) sequence 2: * refuse just texlive-plain-generic: you get the "no more solutions" dialog, so revert this choice (either with undo or hitting "r" again) * now refuse any other, that are known to be refusable one by one: the "Next" choice is greyed out in the bottom-line command summary, and "." just does nothing. Have to kill aptitude to try again. -- Package-specific info: Terminal: screen $DISPLAY is set. which aptitude: /usr/bin/aptitude aptitude version information: aptitude 0.8.8 Compiler: g++ 6.3.0 20170516 Compiled against: apt version 5.0.1 NCurses version 6.0 libsigc++ version: 2.10.0 Gtk+ support disabled.
