I tried to install xdeb on my ubuntu PC (V 10.04), but faced some issues. Attached is the error log. Any inputs?

Hmm right, this is ugly; the story is as follows:

• xdeb uses a script called "debuild" which wraps the usual "dpkg-buildpackage" providing some nice services (like keeping a build log)
• devscripts depends on tons of stuff, including a MTA
• the default MTA, Postfix, fails to install in the chroot

Workarounds:

• mount /proc as amitk suggested, so that the MTA installs
• install without recommends, this probably will avoid pulling a MTA
• pull a small MTA explicitly, or a fake one like lsb-invalid-mta (apt-get install lsb-invalid-mta xdeb -- I didn't actually try this one)

Proper fix, not quite sure:

• perhaps try removing the dep on devscripts by copying debuild in xdeb, or by replacing the functionality?
• only use debuild if available?
• provide better instructions on installing xdeb in a chroot (Amit did it I think!)

For build environment correctness, it is definitely preferred to avoid following recommends at installation.
