Couldn't find a distribution for 'formencode==1.2.6' during installation

(Reported by @alex-obi) Installation with sh build.sh fails with

This is weird, since formencode 1.2.6 should be available.

Mmm, installation works fine on my machine as well as a newly created testing machine. To debug this problem, we need a pcap dump of all network traffic during the installation. Reassigning to @alex-obi to provide that.

On my new debian system i get the same error for a different distribution: "Error: Couldn't find a distribution for ''mr.developer==1.25'". Could this be caused by the latest Virtual Box Update or settings? Tomorrow I'll do the pcap dump.

[phihag]

No, it is completely unrelated to VirtualBox and most likely caused by a transient network failure. Does the problem occur from the hhucn network as well?
