2011-04-08 I have a machine with Debian lenny running. When I exchange mer- curial repos with that machine I get this message: abort: requirement 'fncache' not supported! This error origins in the new, and incompatible, repo format which had been introduced with mercurial 1.1. Unfortunately Debi- an lenny includes version 1.0.1 of mercurial. But there are the backports. Lenny-backports includes mercurial 1.3.1 -- fine. Apt-get allows to install some package in a specific version like this: apt-get install mercurial=1.3.1-1~bpo50+2 mercurial-common=1.3.1-1~bpo50+2 I learned this after reading here [0].
