We need to wait on translations... so maybe another day or two. We'll speed up QA on the new ISOs since almost all cases pass already.
We're adding a new option in the installer to make the call to badblocks optional. When using full disk encryption, badblocks is currently always called to fill the disk with random data... that can take up to 10h on slow HDDs.
Yes, I don't think we'll manage to fix the umount errors on reboot. It's a bit of a race condition and only cosmetic.
Installer tries to unmount all the live mounts...
...but apparently one of these fails. I think I saw the message about squashfs being busy before these errors... it was still used and couldn't be unmounted.
Boot-menu much better!
Still getting SquashFS gazillion errors even if sometimes hidden, and again, nonterminal.
For example, edit the default boot entry to remove the quiet splash -- ... Then shutdown from mint menu...
