I'm pretty sure now that this is a conflict between your locale
setting and the character set used in your vimrc. The machine on
which I have docker installed isn't working at the moment, so
I tried a different experiment. On a machine running Ubuntu 16.04,
I executed the following:

$ LANG=POSIX
$ vim
Error detected while processing
/home/gary/.vim/vimrc:
line 928:
E474: Invalid argument: listchars+=tab:�~V�-
Press ENTER or type command to continue
:set enc?
encoding=latin1

I repeated the experiment with LANG=C with the same results. The
error is at the line where I assign your little triangle to
'listchars'. I don't see this error when my locale is set for
UTF-8, as it is by default. This seems to confirm that your docker
installation of Ubuntu is set up for some encoding other than UTF-8.
That locale setting tells vim to expect the files it sources,
including vimrc, to contain only characters from that character set.

As a solution to this, I added the following at the top of my vimrc:

set encoding=utf-8
scriptencoding utf-8

per ":help :scriptencoding".

With that, I see no errors when I start VIM in the POSIX or
C locale.

You could also execute this in your docker container's shell:

$ locale -a

and see if your language and UTF-8 encoding is supported. If it is,
then just set LANG to that in your ~/.profile, or whatever the
preferred file du jour is for that sort of thing these days.

Regards,
Gary
