I installed ubuntu-20.04.3-desktop-amd64.iso on VirtualBox 6.1.28. It is my first foray into virtual machines and Linux.
I installed Vim 8.1 according to this page. The :scriptnames command shows that the first of the following two files doesn't load, even though the second one does:
- /usr/share/vim/addons/plugin/bufexplorer.vim,
- /usr/share/vim/addons/plugin/ChristiansHi20150126.vim [1]
In unix file access vernacular, both files have "read" permission for "group" and "other".
What would cause this?
My Vim 8.2 on Cygwin loads both plugins just fine, and I've been using both for many years, through various versions of Vim. For Vim 8.2 on Cygwin, the plugin folder is a subfolder of /usr/share/vim/vimfiles.
P.S. I want to use this old version of bufexplorer because I've hacked it to display ~/ instead of /home/User.Name/, which makes better use of limited screen space.

vimfilestoaddonscauses the plugins to be loaded. So the reason why one of the two files above appeared to be loaded was probably because I manually sourced it, or some-such. More web searching reveals that there is an entire layer of vim-addon management of which I was unaware.plugin/*.vimcan be found in the'runtimepath'variable, which you can see with:set rtp?. The documentation indicates it typically includes$VIM/vimfilesby default, but not$VIM/addons. I wonder if an older version of Vim used to useaddons? Or maybe a specific Linux/Unix distribution of Vim used to customize to include that directory? In any way, you could update your vimrc to include$VIM/addonsin that list, or move your files to the locations Vim recognizes...rtppoints to/etc/vim/vimfiles. Theaddonsfolder might be left over from thevim tinythat came with Ubuntu. I can't even invoke it anymore to check itsrtp. The Bash commandwhere -a vimshows two locations, both pointing to/etc/alternatives/vim, which points to/etc/bin/vim.gtk3. The only other Vim-like files in/etc/alternativesisvimdiff, which also points to/etc/bin/vim.gtk3. Is your comment worth posting as an answer, or should this question be removed?addonsas a valid runtime directory, but on the other hand it's definitely plausible... Let me dig a little deeper to see if I can find something that may have configured that name somewhere to make a somewhat better hypothesis. Thanks!addonsfolder. It might have to do with the vim-addon-manager and/or might have come with the Ubuntu ISO image. It might have been installed when I installed Vim.
