4. That failed, so I tried checking the latest release commit:
   git checkout 94929a2f0b662465601abbd686bf080252e76009

   output

   Note: switching to '94929a2f0b662465601abbd686bf080252e76009'.
   
   You are in 'detached HEAD' state. You can look around, make experimental
   changes and commit them, and you can discard any commits you make in this
   state without impacting any branches by switching back to a branch.
   
   If you want to create a new branch to retain commits you create, you may
   do so (now or later) by using -c with the switch command. Example:
   
     git switch -c <new-branch-name>
   
   Or undo this operation with:
   
     git switch -
   
   Turn off this advice by setting config variable advice.detachedHead to false
   
   HEAD is now at 94929a2 Bump version to 2.1.36

@lm-w1n5t0n brawskii, i have found the solution!
simply uninstall rust 'rustup self uninstall'
reinstall it 'curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh'
clone the repo 'git clone https://github.com/racer-rust/racer.git'
cd into it 'cd racer'
then finally run 'cargo build --release'

worked a 💯 persento for me 🥖 👨‍🎨

Duplicate of #1154

Note that rustup skips pulling newer nightlies that missing installed components and falls back to previous releases, so you need to include --force when running update. There were also some subsequent upstream changes in the rustc crates that cause issues on the latest nightly (will be resolved by #1159), but latest on master should build with nightly-2021-02-03

Just tried installing again today and I'm still unable to do so via cargo update

[quadroli]

@koalazub brawskiiiii, did you follow the guide i provided?

[koalazub]

@quadroli I have not, but I'll give it a shot right after work. Cheers for sharing the trick mate!
