It looks like your /tmp is either unwritable or full. Can you confirm if it is?

[sinlesschip]

Sorry I'm dumb, I don't how to do this. I'm not great with Linux.

[sinlesschip]

Okay, I've found in the properties through the GUI it says 182gb free space and all permissions are set to create and delete files.

Don't worry, I'll do my best to help you out. Your original report suggested that you have snap available to you. If you would prefer, you could install rustup through snap which might be easier for you. Try the following command sequence:

$ sudo snap install rustup
$ rustup toolchain install stable
$ rustup default stable

Hopefully that'll sort you out.

Thanks for you help, I ran:
$ sudo snap install rustup
and got this error:

error: This revision of snap "rustup" was published using classic confinement
       and thus may perform arbitrary system changes outside of the security
       sandbox that snaps are usually confined to, which may put your system at
       risk.

       If you understand and want to proceed repeat the command including
       --classic.

Is this safe to run with the --classic flag?

[kinnison]

Aah yes, I forgot you'd need --classic - this is so that the toolchains can actually find and build your code :D It is expected to need --classic at this time.

[sinlesschip]

It worked! Hm I wonder why it wouldn't install with the original command off the docs. Anyways, thank you!

Hijacking this because it's the first thing that pops up when googling this error.

The real solution can be found here, which is that if you installed curl through snap, uninstall it and reinstall through apt.
