[Bug 989396] Re: Package keyboard-configuration post-installation script. Hang on /bin/setupcon --force --save for 10 min then killed

[Raphael Derosso Pereira]

The problem resides in virtual machines with some kind of broken
consoles (or not correctly handled ones).

I narrowed down the problem to the the following command that is run on
setupcon:

setfont -C /dev/tty1 /etc/console-setup/Lat15-VGA16.psf.gz -m /etc
/console-setup/cached_ISO-8859-1.acm.gz

This is the command that locks up. It seems that "setupcon" detects tty
devices wrong and tries to use invalid tty devices passing them to
setfont which in turn is not able to correctly handle the situation.

To be more specific, this "setfont" process locks up in a "write"
systemcall.
