Cannot install cargo-add

[martinellison]

Problem

cargo install cargo-add
Updating crates.io index
error: failed to fetch https://github.com/rust-lang/crates.io-index

Caused by:
object not found - no match for id (7e4727a91e45d8ef9063b0f8fce4d8eda11dfa5c); class=Odb (9); code=NotFound (-3)

Steps

1. Try to install cargo-add

Possible Solution(s)

• Is this the ARM/tool issue again #62558?
• is this (just) a bad error message? What should it say?

Notes

Output of cargo version:

cargo 1.37.0 (9edd089 2019-08-02)

Can you compress ~/.cargo/registry/index and post it online somewhere? I'd like to dig into it and see what's wrong. We've had intermittent reports of this, but I'm not sure how it happens.

Afterwards, you can move (or delete) that directory and try again and see if it works?

[ehuss]

Oh, another thing to do is to run CARGO_LOG=trace cargo install cargo-add and post the output here?

@ehuss: here is the trace:

For some reason, on one of my boxes, cargo install cargo-edit is crashing my box. Not just a segfault, the whole system halts. It gets half way through the compiles and the system just turns itself off. I have no idea why. I have reinstalled the operating system, reinstalled Rust, fscked the disks, and not got any errors. I've tried running the command in the debugger and still got the same result. I'm not saying it is a Rust issue and anyway the worst that should happen (from any sort of Rust error) is a segfault.

Edit: I have done some more testing by installing Rust to a different disk and running cargo install cargo-edit using the new installation. I get the same result, namely a complete system crash (halt). So it is not a storage issue. Somehow a Rust build is crashing my entire system.

This may or may not be related to #3042, but can you zipping up $HOME/.cargo, blowing it away, and retrying? If it works after the retry, can you send us the zipped up version of $HOME/.cargo so we can poke around?

[martinellison]

@alexcrichton

My zip file is 166M and I cannot upload it.

[alexcrichton]

Would something like https://send.firefox.com/ perhaps make it possible to share the file?

[martinellison]

@alexcrichton I have done some further investigation and the situation appears to be as follows:

1. I had an intermittent hardware fault in a PC that made it halt (the entire box stopped, like sudo shutdown now) with less than an hour between failures.
2. The system shutdown while I was running cargo install cargo-edit (not the fault of cargo).
3. This corrupted my $CARGO_HOME file tree.

I have since replaced my PC (it was a $70 mini-PC, so no big problem) with the same model, and now cargo runs fine.

[alexcrichton]

Ok! Sounds like we can close it in that case, thanks for following up though!
