Git 1.7.1 is Not Supported by Bitbucket Server
When trying to install Bitbucket Server on a Linux based server, the following error message is reported:
The minimum supported version of git is 1.7.6. You are using 1.7.1. Upgrade git and restart Bitbucket Server to enable git support.
Bitbucket Server requires atleast Git 1.7.6, but Linux systems come with Git 1.7.1 pre-installed.
Bitbucket Server relies very heavily on the command line options to git commands (such as git log, git ls-tree, etc) and on the git client for handling them. To help avoid exposing bugs in the git client as bugs in Bitbucket Server, Bitbucket Server cannot support earlier versions of Git. Doing so would add considerable maintenance overhead for the product, as well as provide differing levels of quality to the product.
Install the latest version of Git on your Linux server using the package manager for your distribution. For details, see https://git-scm.com/download/linux
To ensure it links with the libs installed on your server, build it from source: https://github.com/git/git
