I downloaded and checked the iso once again and it was deemed OK. Still this issue appears only with this version of Ubuntu back to 16.04.
16.04 works just fine. If the USB stick works otherwise just fine to install either Windows and/or Mageia there has to be something wrong with the installer ubiquity. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874662 Title: Corrupted installation medium To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1874662/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
