Power in my building was cut off when I was updating the packages. After power is resumed, I tried to re-update, but was thrown the following errors. What’s quickest way to get this resolved? Uninstall all packages and re-install? Thanks!!

Thanks for the hint. It almost work fully sucessfully. Yet, I still got the following error about PyPlot. In fact, PyPlot is up-to-date on my machine and I also have had everything else updated. Totally puzzled.

```julia
WARNING: Couldn't initialize pyplot. (might need to install it?)

end
import Conda
Conda.add("qt=4.8.5")

# now restart julia!

Can you do `using PyPlot` on its own from a fresh Julia session?

Hello! I had the same problem (laptop battery died while updating) and I tried the above suggestion (`git reset --hard` in the METADATA folder), but It gave me the following error:

```julia
PS C:\Users\sebastian\.julia\v0.6\METADATA> git reset --hard
error: bad signature
fatal: index file corrupt

```

I am using Julia v0.6.1 on Windows and the error given by `Pkg.update()` is:

My solution was to delete the .julia folder and start fresh.

Came across the same problem again. This time with JuliaPro (v0.6.2). The old trick doesn’t work any more, neither do other methods mentioned above. Any other workaround? Thanks!!

After doing a hard reset at the terminal

```julia
cd /home/chobbes/.julia/v0.5/METADATA
git reset --hard

```

I still get

I also have the `METADATA cannot be updated` problem with a fresh install of JuliaPro v0.6.2 on Windows 7. In my case the problem is with git certificates:

```julia
julia> Pkg.update()
INFO: Updating METADATA...
ERROR: METADATA cannot be updated. Resolve problems manually in C:\Users\Paul\AppData\Local\JuliaPro-0.6.2.2\pkgs-0.6.2.

```

Any help would be greatly appreciated.

Just to be sure the problem is not caused by some leftovers from previous installations, I uninstalled JuliaPro and manually removed all folders with julia in their name (over 2GB) and reinstalled. The problem still remains:

This looks like a known Windows problem with the TLS (IIRC) version because Git now requires the latest version. There was a thread earlier about this issue and there is a Microsoft knowledge base article pointing to an update and also including a quick fixme file that usually works.

I noticed these prerequisites on Julia downloads page, but my Windows claims that these updates (Update to enable TLS 1.1 and TLS 1.2 as a default secure protocols in WinHTTP in Windows and Windows Management Framework 5.1) are already installed.

However Microsoft notes that various things such as adding language packs can negate these updates. In my case, I found I had to reapply the quick fix they provide near the bottom of the relevant KB.

The “easy fix” fixed it. Just installing the update was not sufficient. Thank you for the clue.

Glad it worked for you. That issue had me pulling out what little hair I have left for a bit!

I had a similar problem with JuliaPro 0.6.3.1 on Windows 7 Pro. “easy fix” didn’t seem to work. Perhaps due to my locale…?  
But, Pkg.update() worked today somehow!
