Running rustup update stable or rustup update nightly works without panic.

Same here, trying to update rustup. Successfully updates toolchains, fails to update rustup itself:

[ruabmbua]

Exactly the same here (upgrading to 1.4.0).
Also same error in log as above.

[daboross]

No idea what changed, but I just realized that it has successfully updated to v1.4.0 one of the times that I ran rustup update (I wasn't paying attention because I just was trying to update nightly).

I still don't have a .cargo/bin/rustup-init file, but it seems to have succeeded anyways.

[dtolnay]

I hit this going to 1.5.0. I immediately ran rustup self update and that succeeded.

[makmanalp]

@dtolnay 's solution worked for me!

[daboross]

This is occurring again on my system - not sure if it's related to the original failure. Running rustup self update afterwards or repeatedly doesn't seem to help it. It keeps failing with:

$ rustup self update       
info: checking for self-updates
info: downloading self-update
error: failed to set permissions for '/home/daboross/.cargo/bin/rustup-init'
info: caused by: No such file or directory (os error 2)

As it says, there is no .cargo/bin/rustup-init file. If I create it with touch, rustup will delete it, then error with the same message.

It was fixed by doing both touch .cargo/bin/rustup-init; and chmod +x .cargo/bin/rustup-init. I'm.. not sure why, maybe then it didn't try to change permissions?

[pothos]

For me the problem was solved by closing GNOME Builder before starting the update, otherwise the file would disappear after some time if created manually without invoking rustup yet.

[daboross]

Hmm, interesting. I haven't used GNOME Builder at all, but maybe I had some other thing running which had the same effect.

[daboross]

Running into this again with the latest update.

The workarounds mentioned in my post above (touch .cargo/bin/rustup-init; chmod +x .cargo/bin/rustup-init) no longer work.

rustup show and other rustup commands work correctly. It's only rustup update self (and rustup update' self portion) which error.

Update: running rustup self update once did not work. Running it a second time did work...

Had this again updating to rustup 1.16.0. Same situation as my last post. It failed the first time I ran rustup update, but succeeded a second run.

Ran into this again on a different machine. As with the OP, the solution was to run rustup self update instead.

Unlike last time I ran into this, it fails continuously. Every invocation of rustup update errored with the same error.

I still have no idea what caused this, or why I continue to experience it every so often. It's been 2 years, and this is on a different computer (& different linux distribution) but there's probably something in my environment causing this.

[kinnison]

Other than guessing that you had something else deciding to grab at the binaries I'm unsure what could cause this. rustup self update is the same code as runs at the end of rustup update so there's no specific reason in rustup why one would succeed where the other failed.

[captbaritone]

Similar to @daboross, running rustup self update multiple times worked. In my case I had to run it three times!
