Comment 5 for bug 1628659

Hello,

Same issue.

I noticed error messages about /dev/sda appear during install procedure (near from the beginning), but it disappears too fast to be able to read it, and I didn't find trace of this message in syslog or whatever file I found (in /tmp and /var/log).

I found a temporary solution : add an early-command line in my preseed file :
<code>
d-i preseed/early_command string [ "$(mount | grep /media)" ] && umount /media || echo "no mounted partition found" > /tmp/early.log
</code>

It works well for me (I tried with "grep /dev/sda1" at first times, then I realised whatever the name of the partition is (it can be different, of course, regarding to your disk, partition type...), it's always mounted in /media).

Another info : My PCs are formatted with 3 partitions : sda1 (/), sda2 (swap), and sda3 (/localsettings). I never had this issue before I put files in sda3. It's weird, because sda3 is not mounted, and unmount sda1 is sufficient to fix the problem, but maybe it could help the one who will have to fix that.
