Hi Po-Hsu, I have looked out for this kind of issues but it never re-appeared in any of my tests nor can it be reproduced. By now I'd assume it was some kind of out-of-sync archive in your case.
I'll mark this incomplete, but if you have since then found a way to reliable recreate the issue let me know. ** Changed in: qemu (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1897835 Title: Unable to install qemu-kvm from proposed on Focal s390x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1897835/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
