[X] I searched for recent similar issues at https://github.com/rust-lang/rustup/issues?q=is%3Aissue+is%3Aopen%2Cclosed and found no duplicates.
[x] I am on the latest version of Rustup according to https://github.com/rust-lang/rustup/tags and am still able to reproduce my issue.

Problem

The installation of Rust toolchain freezes when installing rust-docs on a Raspberry PI. The PI that I got here is a Zero 2W, 64-bit (aarch64-unknown-linux-gnu). The system image (RaspiOS Lite Bookworm, 64 bits) was made in the same day, so I doubt there was something messed up in my system specifically.

If I remember well, the only component that hanged the installation was rust-docs, and always soon after reaching 5.4 MB of installed size (I may be wrong, but I think that's it). Setting the installation profile to minimal didn't change a thing.

When I say it "freezes" the PI, I mean that the PI would get completely stuck and irresponsive. The disk write LED wouldn't stop blinking, and I couldn't start any new SSH sessions. Only solution was brute restart. I tried to wait a few hours to see if it eventually completed, but it didn't look as it'd happen.

Then I downloaded the rustup-init script version 1.26 and it worked fine.

Steps

Get a fresh RaspiOS Bookworm Lite system image running on a Raspberry Zero 2W (actually this is the only combination that I could test, perhaps the bug regards only the system and not the hardware, or vice-versa).
Execute curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh and start the installation.
See your PI die as it tries to install rust-docs.

Would you be able to bisect rustup changes to figure out which commit caused the issue?

bernardolansing commented 1 month ago

I guess, but that'll take a while as I'm busy with some things. I'll keep you updated.

Sorry, other than I'm afraid there isn't much I can do make sense of this failure mode.
