Cannot update to 1.15

rustup update stable is currently failing for me

I also tried a rustup self update before trying again and got the same result, versions I tried on were

→ rustup --version
rustup 0.6.5 (88ef618 2016-11-04)
→ rustup --version
rustup 1.0.0 (17b6d21 2016-12-15)

This is updating from

→ rustc +stable --version
rustc 1.14.0 (e8a012324 2016-12-16)

In case this was related to some really old rust install I checked if I had this file anywhere else, but it's only in rustup managed installs and the rust source:

→ find / -name 'gdb_load_rust_pretty_printers.py' 2>/dev/null

/Users/Nemo157/sources/rust/src/etc/gdb_load_rust_pretty_printers.py

I've been able to update many times in the past, so not sure what's different about this release. I also just updated beta to 1.15.0-beta.5 a couple of days ago fine.

I normally develop on nightly anyway, so I'll leave stable as is in case someone has any debugging commands I could run.

Thanks for the report @Nemo157.

I have a hunch of what happened here, and am hopeful it won't happen again. Need further investigation.

[Diggsey]

@brson Status?

[Nemo157]

I still have not touched my stable toolchain since I reported this, just tried again in case something changed between rustup 1.0 and now, still get the same error message

still willing to run any kind of debugging commands if anyone has some.

I had a similar problem when trying to update stable-x86_64-pc-windows-msvc on Windows (rustup version 1.5.0).

I solved it by removing the manifest file of the component that had the conflict (in my case .rustup\toolchains\stable-x86_64-pc-windows-msvc\lib\rustlib\manifest-rust-src).

After this rustup update succeeded.

I am having a similar issue installing 1.33.0-nightly (f960f377f 2018-12-24) alongside a fresh installation of 1.31.1-stable (b6c32da9b 2012-12-18) on target x86-64-unknown-linux-gnu.
Steps to reproduce:

• Remove current installation - rm -rf ~/.cargo ~/.rustup
• Install rustup according to the rustup.rs website - curl https://sh.rustup.rs | sh
• Attempt to install nightly - rustup toolchain install nightly

Output of rustup toolchain install nightly:

Output of rustup show:

Default host: x86_64-unknown-linux-gnu

stable-x86_64-unknown-linux-gnu (default)
rustc 1.31.1 (b6c32da9b 2018-12-18)

[agausmann]

The file ~/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-unknown-linux-gnu/lib/libLLVM-8svn.so exists before and after attempting installation, and it is the only toolchain installed. Removing that file before attempting to install nightly does not work (same error), but the file reappears during installation of nightly, which seems odd.

Main issue is #1590. Current workaround is rustup toolchain add nightly-2018-12-23

With using
rustup toolchain add nightly-2018-12-23

I get same problem.

[agausmann]

Hah, well I used rustup toolchain add nightly instead of ... install nightly and that works for me.

[johanlindfors]

This happened for me as well on my Windows device just now, trying to update to latest stable. Even after restarting the computer (which pretty much works for fixing anything) the error occurred. I ended up deleting all of the folders in the toolchain directory, then running the update process again. Success!

[rbtcollins]

This is another instance of missing/corrupt manifest data. Without knowledge of the installed file, rustup cannot remove it prior to installing the updated version, and then hits a conflict due to the file already existing, and you get the error.

We've got a bunch of these bugs scattered all over the place, I'm closing them all to bring order. See #2417.
