            Bug ID: 6210
           Summary: ValueError: need more than 0 values to unpack
           Product: Mercurial
           Version: 5.2rc0
          Hardware: PC
                OS: Linux
            Status: UNCONFIRMED
          Severity: bug
          Priority: wish
         Component: Mercurial
          Assignee: bugzilla at mercurial-scm.org
          Reporter: iwcom at icloud.com
                CC: mercurial-devel at mercurial-scm.org

Hello. I installed Phabricator and Mercurial in ubuntu server 18.04. I created
an empty repository and when I execute hg clone and hg push, I get HTTP Error
500 errors. I note that if I create a git repository, then there are no errors
with https, there are no errors either if I do hg clone and hg push by ssh. The
error is with hg and https.

I tried to install Mercurial 5.2rc0 from the official site and through apt
install mercurial - the error did not disappear.

hg clone https://test.example.com/diffusion/1/test/
http authorization required for https://test.example.com/diffusion/1/test/
realm: Phabricator Repositories
user: test
password: 
destination directory: test
abort: HTTP Error 500: Error 1: ** unknown exception encountered, please report
by visiting

hg push https://test.example.com/diffusion/1/test/
pushing to https://test.example.com/diffusion/1/test/
http authorization required for https://test.example.com/diffusion/1/test/
realm: Phabricator Repositories
user: test
password: 
abort: HTTP Error 500: Internal Server Error

I also performed a re-installation on another system in VirtualBox and received
a similar error.

Successful SSH connection:

hg clone ssh://vcs-user@test.example.com/diffusion/1/test/
destination directory: test
no changes found
updating to branch default
0 files updated, 0 files merged, 0 files removed, 0 files unresolved

hg push ssh://vcs-user@test.example.com/diffusion/1/test/
pushing to ssh://vcs-user@test.example.com/diffusion/1/test/
no changes found


If I execute the command:
echo listkeys | /usr/local/bin/hg -R /var/repo/4/ serve --stdio
