Steps

1.curl - SSF" https://sh.rustup.rs |After sh
2.Adopt default installation scheme

If you need any feedback, please leave me a message. Thank you very much for your help and look forward to your reply

This looks like CentOS may be missing a library which the new rust release needs. To test that, please run:

$ ldd `rustup which cargo`

And provide the output of that in a comment. My guess is that one or more of the libraries which cargo depends on are not available on your system. If we can identify which, we can work on fixing it.

i'm in this incredibly frustrating loop as well on ubuntu 18

azureuser@datastation:~$ ldd rustup which cargo

ldd: missing file arguments
Try `ldd --help' for more information.

@makslevental Hmm, that error message is worrisome -- What happens if you do:

ls -ld '/home/azureuser/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/bin/cargo' ?

[makslevental]

@kinnison note that I had to install the toolchain using apt-get to work around this. So I uninstalled it (which is fine because I only needed to compile a dep of a python package) and trying to repro again I do not get this error. That is to say that cargo installed successfully when executing curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh. If I have some time soon I will try to repro on a fresh azure instance.

@makslevental any reproduction of the issue since then ?
