I have not seen that one before either
Actually this is set already in fish config (assuming you use it)
## Set environment
set TERM "xterm-256color"
set EDITOR "micro"
While looking at ~/.profile I noticed another TERM is set (TERM=alacritty) so thats quite redundant. Gotta change this! Also:
Probably the ssh session doesnt support session type alacritty and errors out.
