    fatal: Not possible to fast-forward, aborting.

Please accept my apologies #1906

Please remove nvim-tree and reinstall.

git is difficult indeed. today i am getting this:

x nvim-tree.lua:
    fatal: refusing to merge unrelated histories

[alex-courtis]

Try doing a full removal and reinstall: please delete the nvim-tree.lua folder from the file system then run a :PlugInstall
