Error rust syncing channel updates 'nightly — (error reading rustc version)'

Question

I'm having errors with autocomplete so I decided to install everything again but this having this error when doing:

rustup update nightly

info: syncing channel updates for 'nightly-x86_64-unknown-linux-gnu'

nightly-x86_64-unknown-linux-gnu unchanged - (error reading rustc version)

in rust rustc 1.17.0

When doing:

->rustup override set nightly-x86_64-unknown-linux-gnu
info: using existing install for 'nightly-x86_64-unknown-linux-gnu'
info: override toolchain for '/home/' set to 'nightly-x86_64-unknown-linux-gnu'

  nightly-x86_64-unknown-linux-gnu unchanged - rustc 1.19.0-nightly (d3abc80b3 2017-05-09)

Is able to recognize now:

nightly-x86_64-unknown-linux-gnu unchanged - rustc 1.19.0-nightly (d3abc80b3 2017-05-09)

instead of

nightly-x86_64-unknown-linux-gnu unchanged - (error reading rustc version)

Then I do update nightly because maybe it was corrupt or maybe not and it is normal, and maybe it would have worked

->rustup update nightly
info: syncing channel updates for 'nightly-x86_64-unknown-linux-gnu'

  nightly-x86_64-unknown-linux-gnu unchanged - rustc 1.19.0-nightly (d3abc80b3 2017-05-09)

I did some tests and at first did not recognize it rustc 1.19.0-nightly (d3abc80b3 2017-05-09) I had to execute 2 times ->rustup update nightly

According to was looking can be used toolchain uninstall but this last I can not confirm:

->rustup toolchain uninstall nightly
info: uninstalling toolchain 'nightly-x86_64-unknown-linux-gnu'
info: toolchain 'nightly-x86_64-unknown-linux-gnu' uninstalled

->rustup self update

//..
->rustup update nightly
//..

Note: Maybe this (error reading rustc version) Really is not any serious "error" and can work without recognizing the version rustc 1.19.0-nightly (d3abc80b3 2017-05-09)
