I have tried to run *update-manager* of lenny whole day. But at last i found that, it is a *major* bug of lenny. The problem is, it requires newer version of python-apt but the stable python-apt is 0.6.17 which is in testing lenny.
I also tried with downloaded python-apt version 0.6.19 and 0.7.2, but changed nothing.... check this: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=431114 Zico -- http://mohibuzzaman.blogspot.com [Non-text portions of this message have been removed]
