[Tex/LaTex] Unsupported Protocol in MiKTeX package manager

miktexmiktex2.9

I have had a MiKTeX installation on this computer for several years and it has worked mostly smoothly. However, since today, when trying to install new packages using the package manager I get the following error:

MiKTeX Problem Report

I can still run MiKTeX as usual, i.e. build documents etc, but any attempt to install new packages gives this error message.

In addition, If i try to change my remote package repository, I get this very cryptic list of repositories:

I have, to the best of my knowledge, not changed anything with the MikTeX installation myself since the last time I successfully used MiKTeX.

Edit: I have now encountered this problem on 3 of my windows machines, including 2 with windows 7 and one with windows 10. They all get the exact same error message and were all working just a few days ago.

Apparently, it was a bug on the server side and the maintainer (Christian Schenk) has fixed it. Should work now (it does on my machine without the need to reinstall anything) https://sourceforge.net/p/miktex/bugs/2609/
