Mercurial HG: "hg push" returns abort: HTTP Error 500: No such file or directory

Question

I am using mercurial and when I am trying to use hg push, I am getting this error:

abort: HTTP Error 500: No such file or directory

Server information:

• Nginx with Mercurial
• Debian 7.1

Any idea why? The pull works fine.

EDIT: By enabling to push with http, I am able to see a stack trace: error.html

EDIT2: However, if I disable the possibility to use http, the initial error comes back.

EDIT3: Here is the error when I am doing the trackback:

EDIT 4: The repos hgrc file that is placed in /usr/mercurial looks like that:

[web]

deny_push = root, mdpiadmin, www-data
allow_push = milos
contact = Geeks MDPI AG
verbose = true

[trusted]
users = www-data
groups = www-data

[ui]
editor = nano
merge = vimdiff

EDIT5: ngnix error log:

Here is the error log on ngnix side when I am trying to do the push:

Answer 1

This is only a guess, cause I read you are using nginx with cgi?

Usually you setup the server

hgweb.config

or each repository

.hg/hgrc

to allow push

[web]
allow_push = *

Have a look at https://www.mercurial-scm.org/wiki/HgWebDirStepByStep?highlight=%28allow_push%29#Allow_pushing_to_the_repository

---

On your local repository in .hg/hgrc you will need a default path and the authentication details to perform hg push.

[paths]
default = <repo-url>

[auth]
devserver.prefix = https://hg.mdpi.com/
devserver.username = <your-name>
devserver.password = <yout-passwd>

I doubt that hg push https://hg.mdpi.com/ will work, cause there is no repo-name in it ..

hg push https://hg.mdpi.com/reponame

would be legit.
