Bug #2982

ncurses installer fails silently

telur - almost 3 years ago - . Updated over 2 years ago.

in progress
% Done:



after every installation step of parabola, the console shell get immediately replaced by ncurses installation interface, truncating possibly end error messages behind. it would be nice if there is a stop in like "the command is finished, press "enter" to go to next installation step" so user had a time to spot and make sure there is no error message in console shell occured.

a common issue like this is when pacman fail because of pgp signature error but user had already drawn into ncurses installation interface again and had no idea wheter the command executes successfully or not that might lead into total installation failure especialy for newbies and those who still in learning stage, if they can spot an error at least they know where is something wrong and not just bump installation fail into bugtracker.

none of the text is replaced or deleted - you can scroll back
to see everything that happened in previous steps

isnt half end of scrollback buffer is occupied/truncated by next ncurses menu displayed ?
though this is my past experience and i dont have the anymore.

anyway im just figure out putting this perks in each command step will ask user to press enter before next ncurses menu fill the screen so user can view the scrollback buffer freely before going into next step.


  1. bash stop in prompt
    read -p "command finished, press "enter" to go to next step"

one of the first things i noticed when i first used parabola was
how terrible that installer is

the real problem you are pointing at is that the installer can
fail silently; but then continue, although it makes no sense
to continue - the real solution is to detect errors and quit
with a meaningful error message

last year, i re-wrote it almost completely - the new version
will dump a back-trace indicating exactly which command failed,
and then exit gracefully

so, i was not denying the problem - only i did not mention that
this problem is already known, and a good solution is mostly
completed - i have not had the time to debug it thoroughly yet

if you have good shell debugging skills, feel free to try it out
- i dont remember how well debugged it is yet - IIRC, you
would need only the files in the .session/ dir and start it
with '' - bear in mind that it is a dangerous
script, which runs as root; so it is best to experiment in a VM
