Public bug reported: The Ubuntu devel suite isn't a proper suite, just a symlink:
$ curl -s http://archive.ubuntu.com/ubuntu/dists/devel/Release | egrep 'Suite|Codename' Suite: disco Codename: disco I would expect this output instead: $ curl -s http://archive.ubuntu.com/ubuntu/dists/devel/Release | egrep 'Suite|Codename' Suite: devel Codename: disco People using devel in their sources.list get a warning from apt: $ chdist create ubuntu-devel Now edit ~/.chdist/ubuntu-devel/etc/apt/sources.list Run chdist apt ubuntu-devel update And enjoy. $ sed -i '/ubuntu/{s/#//;s/dapper/devel/}' ~/.chdist/ubuntu-devel/etc/apt/sources.list $ chdist apt ubuntu-devel -qq update All packages are up to date.
