Installing on Windows 2016 fails because of TLS versions #2085

Open gozdal opened 5 months ago

gozdal commented 5 months ago

When trying to install uv in our CI env I noticed that Windows 2016 boxes failed to download the install script because of Could not create SSL/TLS secure channel. Later Windows versions were fine.

I worked around it with:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12;
irm https://astral.sh/uv/install.ps1 | iex

Perhaphs it'd be good to add it to the docs?

We explicitly pass --tlsv1.2 to curl for the shell installer already, so that seems supremely reasonable for the powershell installer to set too.

Could you confirm for me that this expression works on your windows server?

irm -SslProtocol Tls12 https://astral.sh/uv/install.ps1 | iex

(It's probable once the script downloads it will then error trying to fetch the actual binaries, but that's easier to fix than the raw irm | iex)

Unfortunately not: obraz

Ah shoot, yeah that flag is relatively bleeding edge (and maybe Powershell Core exclusive?).
