We are starting to use Mercurial for source control. We have configured the HGRC configuration file to do an auto update after we push to the "central" repository. With some PCs we get this error msg:
warning: changegroup hook exited with status -1
HGRC looks like this:
[ui]
username=ADMIN
verbose=true
[hooks]
changegroup = hg update >&2
Later we perform the update manually and everything works right.
