package mysql-server-5.1 5.1.58-1ubuntu1 failed to install/upgrade: el subproceso instalado el script post-installation devolvió el código de salida de error 1

Hello,

I'm not sure this is a serious bug.

I did some investigation and can confirm you can't install mysql-server-5.1 on a running oneiric desktop livecd because you can't get job status when running "status mysql" from the livecd (returns status: unknown job mysql).

Installation works without any issue when running on an installed system (tried both i386 desktop and amd64 server), so i would suggest to only install it on a running system.

Problema resuelto
===============

Efectivamente el problema se daba al realizar una instalación en un pendrive USB. La solución (fué puro azar) fué la siguiente:

- Instalé aptitude (sudo apt-get install aptitude)
- Luego instalé el mysql-server con aptitude (sudo aptitude install mysql-server)
- Me dió el mensaje de error comentado anteriormente
- Reinicié el equipo
- Instalé mysql-client con aptitude (sudo aptitude mysql-client)
- Durante este proceso de instalación aparecieron algunos mensajes de advertencia y como final de proceso se corrigió el problema y todo rueda correctamente.
- Instalé posteriormente apache, php5, php5-mysql y phpmyadmin y todo funciona correctamente.

Above translated:

problem solved
===============

Indeed the problem occurred when performing an installation on a USB pendrive. The solution (it was pure chance) were as follows:

- Install aptitude (sudo aptitude install apt-get)
- Then I installed the mysql-server with aptitude (sudo aptitude install mysql-server)
- I got the error message mentioned above
- Restart the computer
- Mysql-client installed with aptitude (sudo aptitude mysql-client)
- During the installation process there were some warnings and end of the process as the problem was corrected and all-wheel correctly.
- Then I installed apache, php5, php5-mysql and phpmyadmin and everything works fine.
