vim 9.0 dont recognise stuff from 8.2

[Igor Lerinc]

i had vim 8.2 , and system wide settings in /etc/vim , where  vimrc is located, but now, vim 9.0 doesn't recognise it, it installed itself in /usr/share/vim  , tried creating symbolic link there, to my /etc/vim, but it doesn't recognise it, it shows something like that it can't load default settings.

also, my plugins which are located in home directory are broken, it can't load them, i don't know how much of vimscript has changed, but, nothing works.

my plugins are: plugged , undo_dir , lightline, fzf-master

And this is my vimrc file, i don't know how much and what is supported by new version (and how to convert to make it usable) :

" All system-wide defaults are set in $VIMRUNTIME/debian.vim and sourced by

" It is recommended to make changes after sourcing debian.vim since it alters
" the value of the 'compatible' option.

Please check the complete output of :version in both versions and check
the value of system vimrc file. That should ideally point to the correct
file which on my system is a symlink to /etc/vim/vimrc

Also, from within vim, simply do `:echo $VIM .. "\n" .. $VIMRUNTIME`
should show you where those Variables point to.


Best,
Christian
