The dump is available here if people want to join the > party: dump.guix.gnu.org/download/installer-dump-304492ff. So the backtrace suggests that we are trying to open /dev/nvme0n1p1 to read its superblock: --8<---------------cut here---------------start------------->8--- 9 (open "/dev/nvme0n1p1" 524288 #) --8<---------------cut here---------------end--------------->8--- and that it fails because the file does not exist: --8<---------------cut here---------------start------------->8--- 1780:13 6 (_ #<&compound-exception components: (#<&external-error> #<&or= igin origin: "open-fdes"> #<&message message: "~A"> #<&irritants irritants:= ("No such file or directory")> #<&exception-w=E2=80=A6>) --8<---------------cut here---------------end--------------->8--- This open call originates from check-user-partitions in (gnu installer parted). If we arrive here, it means that the file *should* exist. Looking at the kernel trace, the two last lines are: --8<---------------cut here---------------start------------->8--- [ 72.271204] nvme0n1: p1 p2 p3 p4 [ 127.415648] nvme0n1: p1 p2 --8<---------------cut here---------------end--------------->8--- so the disk partition table is updated because we move from 4 to 2 partitions. Could it be possible that during a brief period of time the /dev/nvme0n1p1 file disappears then re-appears? I'll try to reproduce it a VM to conduct more testing. Mathieu
