I understand that nvim_buf_set_virtual_text is now deprecated, so I started looking for my neovim version so I could know why this new function is not included.

In Ubuntu Focal (LTS) the default neovim version is v0.4.3 vs the stable neovim release v.0.5.1. As a possible solution, please consider checking the installed version in order to set the proper function.
