Is it no-longer possible to use dd to write an install ISO to a flashdrive, or is there something wrong with the ISO (which passes the checksum tests)? If I do this command: [root@rocky fedora42]# dd if=Fedora-Server-dvd-x86_64-42-1.1.iso of=/dev/sdb status=progress 2923241984 bytes (2.9 GB) copied, 1204.794829 s, 2.4 MB/s 5714688+0 records in 5714688+0 records out 2925920256 bytes (2.9 GB) copied, 1212.03 s, 2.4 MB/s Marvel at the blistering write speed!!

That's expected and has always been. The image you're writing is not exactly the same size as the media, so there's no way to have the alternate header in the right place. You can fix it or ignore it.
And it can't be mounted.
How are you trying to mount it? -- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
