Installing nightly fails with failed to install component

[flaviut]

I'm trying to install nightly for the first time, but I'm getting the following error:

info: syncing channel updates for 'nightly-x86_64-unknown-linux-gnu'
info: latest update on 2018-12-25, rust version 1.33.0-nightly (f960f377f 2018-12-24)
info: downloading component 'rustc'
info: downloading component 'rust-std'
info: downloading component 'cargo'
info: downloading component 'rust-docs'
info: installing component 'rustc'
info: installing component 'rust-std'
info: rolling back changes
error: failed to install component: 'rust-std-x86_64-unknown-linux-gnu', detected conflict: '"lib/rustlib/x86_64-unknown-linux-gnu/lib/libLLVM-8svn.so"'

What I've tried:

• deleted ~/.rustup and tried again
• reinstalled rustup using my package manager

I also ran rustup under strace. It appears that rustup at some point creates libLLVM-8svn.so, but then it complains about a conflict? Could both rustc and rust-std contain this same file and clobber each other?

Stable works fine, only nightly has this issue.
