YaST2 pops an error about installation media each time I install new stuff.

Hello, I’ve just installed Tumbleweed with XFCE.
Whenever I open the YaST software manager and mark some stuff for installation, when pressing Apply, I get this error:

After clicking RETRY everything works fine. But it’s annoying since it happens every time. Since it’s not a network issue, I suspect a BUG in YaST perhaps?

I get the same error when using zypper from the command line:


sudo zypper install twm
...
Retrieving package twm-1.0.9-1.2.x86_64                                                      (1/1), 113.2 KiB (232.7 KiB unpacked)
Media source 'http://download.opensuse.org/tumbleweed/repo/oss/' does not contain the desired medium


**Abort, retry, ignore? [a/r/i/? shows all options] (a): **

If I hit ‘r’, it will work fine the second time.

sounds like a bad mirror there is nothing you can do about it, if that mirror’s admins don’t fix it you can try and manually add a mirror near you
