1100031 - Can't commit to nb-NO beta l10n repository, getting python error on hgwebjson

Status: RESOLVED DUPLICATE of bug 1100027

(Developer Services :: Mercurial: hg.mozilla.org, defect)

Description

[Håvard Mork]

I'm getting this error when trying to push to the repo http://hg.mozilla.org/releases/l10n/mozilla-beta/nb-NO/
(also occurs in the corresponding nb-NO Aurora repository, possibly others - but haven't checked)


[hmork@serve nb-NO-beta]$ hg push

Since the error messages provide a "remote:" prefix, I believe this is a server-side problem in a mercurial hook.
