Public bug reported:
1. Download ubuntu-19.04-live-server-amd64.iso from https://ubuntu.com/#download 2. Confirm I have the same sha1sum as published from http://releases.ubuntu.com/19.04/SHA1SUMS 3. Boot the ISO in a qemu kvm VM using virt-manager 4. Choose 'check disk for defects' option - disk passes 5. Boot again, switch to tty2 6. dmesg | grep SQUASHFS Actual result: Multiple squashfs related read errors [ 4.769520] SQUASHFS error: squashfs_read_data failed to read block 0x6261746d79732e [ 4.769548] SQUASHFS error: Unable to read metadata cache entry [6261746d79732e] Expected result: squashfs shouldn't complaint about errors in the image Additional information: The block address reported is different each time I boot.
