Download progress indicator doesn't show up. Needs term >= 0.5.0 ?

[ynakao]

Today I noticed when upgrading Rust v1.24.1, download progress indicators didn't appear at my Arch linux PC.

At macOS machine, download ETA showed up properly.

This function is handled by download_tracker.rs, and to write the info on the terminal term crate is necessary. So, I searched at term crate issues, found the one which seems to cause this problem. According to the discussion, if installed ncurses version is above v6.1 this happens, and they released fixed term v0.5.0.

My Arch has ncurses v6.1, and I tested other machines. In Debian stable which has v6.0 download indicator worked, but Debian testing which has v6.1 it didn't work (ncurses-bin). macOS may have v5.x since there's /usr/bin/ncurses5.4-config.

Also I tried cloning this repo and build rustup localy with the change term = "0.5" in Cargo.toml (currently term = "0.4.4") at my Arch machine. In the result, rustup worked fine displaying ETA messages.

Therefore, I think it needs to change rustup dependency information especially term crate version number. I'm sorry if I'm wrong.

Same here. Arch Linux + Yakuake + Zsh.

Same here. Progress is not shown anymore on Linux, while is working perfectly on macOS and Windows.

OS: Arch Linux (kernel 4.16.6-1)
Shell: Zsh 5.5.1

A PR for this would be welcome

I just submitted PR #1422.

Sadly we're stuck on an older term until/unless we can replace it with something else entirely. Term 0.5 broke Windows. We have other issues open for finding a replacement.
