I noticed this a while back but kept forgetting to get some screenshots. Not sure when exactly it started but some downloads (Firefox is where I notice it the most) a strange character (y with dots over it) is added to the filename. See the attached screenshots. One is downloading it directly and the other is letting Astaro do the download then grabbing it from there. And yes, when I download it from Astaro that character stays in the filename. Doesn't seem to cause any problems, just something odd I noticed. Thanks!!
okay, it took a moment, but i was able to track this down to a misconfigured webserver or perhaps load-balancer in front of mirrorservice.org that doesn't send any encoding information.
try the url that you posted above and the url from your screenshot with eg. ` curl -I ` and you'll see the diffenrence.
