cannot download nonexistent lean

[philderbeast]

On first use of elan it is complaining about a nonexistant lean version it cannot download.

I think I did a make install for lean4 maybe a month ago. I only installed elan today. It had complained that I had an existing installation of lean in /usr/local/bin so I deleted what lean things I had in /usr/local/bin and then (possibly after using vscode version management|setup|install elan) I installed elan from the command line with instructions for the development setup;

$ curl https://raw.githubusercontent.com/leanprover/elan/master/elan-init.sh -sSf | sh -s -- --default-toolchain none

I have these in my profile;

$ type lean
lean is ~/.elan/bin/lean

$ type leanmake
leanmake is ~/.elan/bin/leanmake

$ type leanc
leanc is ~/.elan/bin/leanc

$ ls ~/.elan/bin

I was then able to link so I'm good to go but those error messages had me worried that things were messed up;

$ elan toolchain link lean4 build/release/stage1

$ elan toolchain link lean4-stage0 build/release/stage0

$ elan show
