I have recently carried out the apt-get upgrade -u and to find after it that:
My firefox doesn't work anymore, message:
(Gecko:1610): Pango-WARNING **: No builtin or dynamically loaded modules were found. Pango will not work correctly. This probably means there was an error in the creation of:
'/etc/pango/pango.modules'
You may be able to recreate this file by running pango-querymodules.

There is also my azureus:
Staring Azureus...

They all look like problem due to pango. But I have not been able synaptic or apt-get install pango. Please help.

Thanks,

My first suspicion would be that you are running Sarge, and did an upgrade from "Stable." Sarge is no longer "Stable" You have probably done a partial upgrade to Etch, the new Stable, and things could be a little messy. If that diagnosis seems resonable, study the Release Notes, and finish the job.

So my question to my above problems

1. is there any way to solve them, or
2. how do i revert the changes made by apt-get upgrade

Wilson

Well, indeed I have sarge installed. But all I did was to point my sources.list to debian's site, then update then upgrade. So I really have no way of telling which part of sarge was upgraded and which part belonged to Etch.

I am now trying to revert my sources.list to my CDs and run apt-get upgrade again to see if I have any luck in rescuing my system.

The few programs I found broken are :
1. azureus
2. Firefox
3. Synaptic

most of them point the fault to pango, but I just couldn't find the right pango from apt-cache search pango. I have to depend on apt-get now as my synaptic doesn't work anymore after the upgrade.

Wilson
