msys2 out of whack

[Dann Corbit]

Since yesterday, I have not been able to synchronize my msys2 installation. I get errors like this:

Code: Select all

$ pacman -Syu

I did some searches but none of the example ways to fix it have done anything useful.

I don't suppose someone knows a simple fix for this mess?

If someone else runs into this problem, here is how to fix it:
pacman-key --init
pacman-key --populate

And a couple cycles of:
pacman -Syu
