I got the following error when I tried to update the packages. I use Pkg.checkout(“CSV”) to get the latest version of CSV.jl. Today, I called Pkg.free(“CSV”). After doing this, I cannot update the packages. (Window 7, pro, 64bit, Julia0.6.2)

```julia
Pkg.update()

```

The test of Base “libgit2” fails as follows. This error cannot be solved by reinstall Julia.

```julia
Base.runtests("libgit2")

```

The error is as following.

Please don’t use screenshots, they are difficult to read and copy. Use [backticks](https://discourse.julialang.org/t/psa-how-to-quote-code-with-backticks/7530).

This may be related to [this issue](https://github.com/JuliaLang/julia/issues/13399). I would first try git from the command line and approve if it prompts for certificate validity.

Thank you for advice. I have tried to find the answer on the website, but still cannot solve it.

Thanks, @Tamas_Papp, It should be a new error. Other people also report this issue ([Issue: 26167](https://github.com/JuliaLang/julia/issues/26167)). Pkg works yesterday, just have the problem today. Maybe, It is related to the setting of the server holding the packages.

I reinstalled Julia0.6.2. When I run `Pkg.init()` in the new installed Julia, I got the similar error as follows.

```julia

Github dropped support for old cipher suits last night. Apparently our windows MbedTLS builds ask for old versions. Julia on Linux works for 0.6, but fails on 0.5.

This does look like a critical issue (at least on windows – 0.5 is really really unsupported at this time for linux), and hopefully we’ll come up with a workaround as the day goes by.

@avik Thanks for your explanation! Are there other ways to install the package of Julia? After I reinstalled Julia, I cannot install any package. I changed most of my data processing for the work to Julia now. Currently, I cannot do the work.

Sorry, only thing I can say right now is use Linux or Mac :(. Rest assured many people are looking at this now, as they wake up. Hopefully will have an update soon.

@avik Really thanks for your help! I can change to Linux for the work. I spent the whole afternoon on this 😅.

So @staticfloat found this Windows registry setting that enables TLSv1.1, since on Windows LibGit2 uses WinHTTP as the default provider. We’ve verified that this does seem to work.

> **[Update to enable TLS 1.1 and TLS 1.2 as default secure protocols in WinHTTP...](https://support.microsoft.com/en-us/topic/update-to-enable-tls-1-1-and-tls-1-2-as-default-secure-protocols-in-winhttp-in-windows-c4bd73d2-31d7-761e-0178-11268bb10392)**

Run the easy-fix tool that is available on that page (or make the registry entries manually)

Thanks to Elliot.
