package libruby1.8 1.8.7.249-2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

Binary package hint: ruby1.8

I cannot get rid of error messages concerning ruby..... it originally happened when the upgrade process got disconnected from the Internet in mid-process. Since then, I have tried completely removing Ruby (see exact packages below) but I get the error message at the bottom this message:

You use a Geode CPU, which is not supported by maverick. Are you sure that you are installing the package in lucid, not maverick ?

[David Nelson (commerce)]

Hi, :-)

I've got Ubuntu 10.04, and this is a Core 2 duo...

Thanks, :-)

Ah, I misread the dmesg output.

You should try to dpkg --purge the package, clean the apt cache, and
reinstall it.

Since you seem to be the only one affected, it's likely to be caused by
a corrupted file somewhere.

I tried the dpkg --purge and cleaned the apt cache but it still does not resolve the problem...

As a reminder, this problem originally occurred when my internet connection went down following a power outage during the upgrade from 9.10 to 10.04 (i'm on a laptop, so the computer was still working). I had to do a power off/power on to restart the system at that time...

If you're interested in any further details, please do ask...

Thanks for your great work guys, and more power...

[Lucas Nussbaum (lucas)]

What's the content of /var/lib/dpkg/info/libruby1.8.postinst ? is there something strange in it? What happens if you run that script manually?

[David Nelson (commerce)]

Hi Lucas, ;-)

Thanks for your reply... No, it's completely empty...

David

[Lucas Nussbaum (lucas)]

It shouldn't be empty. Can you replace it with an executable file with:
#!/bin/sh

exit 0

in it ?

[David Nelson (commerce)]

Hi Lucas,

I did as you suggested and the problem seems to be solved. The last
updates were installed with no error messages at the end.

Thanks for your help, Lucas, and a big thanks to all the people who
bring us Ubuntu. ;-)

David Nelson

ok, closing :-)
