Description
This "not installed" message happens when the toolchain parser fails to parse the name and then considers it a "custom" toolchain. After that, the operation fails, and the reason is because there is no custom toolchain with that name.
It's confusing though because the user may have typo'd a channel name, not expecting it to be installed.

Research direction
Start by tracing the toolchain parser and the code that produces the “not installed” message. Reproduce the behavior with the nightly-foo name and determine how parser failure is distinguished from a missing custom toolchain. Done means the error explains the invalid or unrecognized channel without misleading users about installation.
