What is in your my.list.chroot?Because it fails at the"P: Begin queueing installation of package lists (install pass)..." stageSo maybe some misspeling in package or package that doesnt exist (but well it should be then in the log) Try toset this ...and this... in you /config/common:# $_VERBOSE: enable verbose# (Default: true)_VERBOSE="true"# $_DEBUG: enable debug# (Default: true)_DEBUG="true"And then try to build with lb build --verbose. Maybe there will be more info in the log.
