I think the repo may be messed up? Or maybe it's me? I don't know.

Not just you. 😞 Thanks for filing the issue.

@leecow, looks like the hash mismatch issue is happening again. Can you ping the repo admins?

[dagood]

I sent the repo admins a high-pri mail about this issue, we will hopefully have more info soon.

(There are backlinks, but note that this is also being discussed and tracked at https://github.com/dotnet/core/issues/3221, and that's where most people will probably look first.)

[mdee77]

same for me. waiting for a fix.

[marcwittke]

it's working for me now

[herebebeasties]

I don't think this was manually fixed - looks like a new drop has happened and the files didn't get screwed up this time. Must be a race condition or something in the release process.

@dagood This is a recurring issue. See at least:

• microsoft/vscode#41094
• microsoft/vscode#45868
• dotnet/core#2608
• dotnet/core#3221
• microsoft/msphpsql#938

Any chance of some proper root cause analysis and fix for this?

(And jeez, everyone please stop adding "me too" comment spam to things. Eighteen thousand copies of the same error message is really unhelpful for the signal-to-noise ratio in tickets like this.)

[dagood]

The repo owners confirmed they've fixed this now.

@herebebeasties I would like that, I'll see what info I can post over at https://github.com/dotnet/core/issues/2731 where this question has also come up.
