After updating MikTex last night I am getting the error message in subject when trying to install or update the packages.
By default I was using http://ctan.mirror.rafal.ca/systems/win32/miktex/tm/packages/ but to try and recover from this error I switched the updater to use the "nearest" repository which happened to be http://ctan.math.ca/tex-archive/systems/win32/miktex/tm/packages and that also threw the same error.
Then I changed the updater to "allow me to choose the package repository" but the list that comes next is empty.
Did the last night's update to MikTex break the repository listing/querying in general, or something is wrong with my installation?
