For the record, we fell onto the same issue with the RISC-V live installer on the SiFive Unmatched board whose logs are attached. In those logs you'll see a kernel bug that I'm currently investigating which is likely caused by the md5check job.
Adding fsck.mode=skip to the command line fixed the issue for us. ** Attachment added: "log_fail_cloud_init.tar.gz" https://bugs.launchpad.net/subiquity/+bug/1946773/+attachment/5570361/+files/log_fail_cloud_init.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1946773 Title: "An error occurred.
