Rustup: Rustup install in bad state

[jonathandturner]

Not exactly sure what happened, perhaps a broken automatic update? The compiler was working, and then I started getting errors about rustc not being found. When I tried to rustup, I get:

Update: confirming that I had RLS set to auto-update tools via a workspace setting.

I tried blowing away ~/.cargo/bin/rust-gdb and ~/.cargo/bin/ and then tried reinstalling rustup

no dice. help?

[softprops]

without a better workaround I did a rustup self uninstall then tried reinstalling rustup and that seemed to do the trick. hope this helps someone else

The underlying issue here is that rustup update foo does not run a self update. There is a long-term fix here, but rustup does get into a weird state when it has a cache of the manifest using the old rustup.

An alternate workaround is to add the nightly toolchain, wait for the next nightly release and then run rustup update

[softprops]

unfortunately my motivation here was my excitement for a the stabilization announced here. I was actually kind of surprised when I ran into this. I update with every new release and have been using rust since before there was a stable :) this was honestly the first time I experienced any trouble updating. perhaps something related to the new edition was related.

rustup uninstall stable
rustup update stable

Since this transition is well past, I'm just going to close this.
