Sorry for not posting this at the chat, i cant register new account down there so github is the only hope. Newbie to Linux

I have exactly the same issue on Dell 5520, trying to dual-boot alongside Ubuntu 16.04

I used GParted to shrink Ubuntu partition and created a new primary partition for PopOS and a Swap, after selecting the new partitions and clicking on Erase and Install I get this error. The only difference is:

INFO: libdistinst: installing Config { hostname: "pop-os", keyboard_layout: "us", keyboard_model: None, keyboard_variant: None, old_root: None, lang: "en_US.UTF-8", remove: "/cdrom/casper/filesystem.manifest-remove", squashfs: "/cdrom/casper/filesystem.squashfs", flags: 3 } with Bios

Problem occurs with both Intel/AMD and nVidia ISO images

I have the same problem:

ERROR: device unmount error: unable to unmount partition(s): Device or resource busy (os error 16) ERROR: initializing error: unable to unmount partition(s): Device or resource busy (os error 16)

The solution is here: https://www.reddit.com/r/pop_os/comments/8r9dbh/pop_os_1804_installation_failed/

Close the install wizard, continue in try mode, open the terminal:

sudo su
apt update && apt upgrade

Open Install Pop OS and try again.

Too bad, I wish I found this workaround before ... I had to go on, and went for Ubuntu

The solution on reddit works. You must close the installer and go to live and open a new installer.

Solution works but they can update there iso.

The iso was updated yesterday afternoon. This issue should no longer happen on the new iso(25). I am going to close this issue but feel free to reopen/comment if you continue to have issues.
