end)

I have a mostly minimal config now. Should be noted that I am running this on a server on which I do not have root access. Additionally, the number of forks I can create is limited, so I have set the max jobs to 1 to prevent other errors. Finally, because of the old git version, I changed --rebase=false, which previous errored as an undefined flag, to --no-rebase. The rest of the config passed to packer.init should be copied from the defaults.

Your git version is too old, it doesn't support some flags for the update, get_header and submodules subcommands in packer.lua.

They need to look like this in the file:

...
update = 'pull --ff-only --progress --no-rebase'
get_header = 'log --color=never --pretty=format:FMT HEAD -n 1'
submodules = 'submodule update --init --recursive'
...
