Apprently there is a bug with the version of git for openWRT, which affects the onion.
When doing a git pull on a already cloned depository I get the following
root@Omega-13E3:/usr/share/htdocs/api# git pull
/usr/lib/git-core/git-pull: exec: line 1: git-merge: not found
After doing a "find / -name 'git-core' it is reveiled that git is placed both in
Following what was written on this post https://dev.openwrt.org/ticket/11930 I mananged to fix the problem
The following command fixes it: "ln -s $(which git) /usr/lib/git-core/git"
As far as i get tell. This creates a symlink from the core lib to where git is called or something like that. Anyways it fixes the problem with merging and pushing
