[MiKTeX] Verification failed

[Marvin K. <1ka...@in...>]

Dear all,

I am a happy user of MiKTEX for some years now and first of all great
thanks to all the work!

Today I felt the urge to update my MiKTEX as it is a good habit from
time to time and then I ran into the following verification error:

When I re-executed it, everything seemed fine. But as a person who
prefers to be on the safe side: Is there any problem with the mirror?
Was some data maybe really altered?

Best wishes,
Marvin
