** Description changed: + [Impact] + This impacts any network installs specifying live-installer/net-image (ie. using live-installer to install using a squashfs instead of debootstrap) + + [Test case] + 1) Boot on netinstall image to grub menu; it 'e' for edit; + 2) Add 'live-installer/net-image=http://cdimage.ubuntu.com/ubuntu-server/xenial/daily/current/xenial-server-amd64.squashfs' to the linux line. + 3) Hit F10 to boot with the changes. + + Installation should complete successfully. + + [Regression Potential] + Minimal; this is meant to fix a bug that was introduced that currently breaks all uses of net-image that don't use a path relative to /cdrom, which used to be possible; and only enforces the proper handling of URIs as absolute paths instead of prepending them with '/cdrom'. URI-like syntax in typical filesystem paths is not something that is supported. + + --- + Attempting to use PXE to install 16.04 results in an error dialog that states "The failing step is: Install the system". Checking syslog shows that it has prefixed the URL to the filesystem.squashfs with "/cdrom" and failed to find the file. base-installer: info: Downloading /cdromhttp://192.168.1.251/ubuntu-1604.amd64/install/filesystem.squashfs to /tmp/live-installer/filesystem.squashfs Setting the path to the filesystem.squashfs by either the "append" option in the PXE default file, or as a preseed option in the kickstart file both have the same result.

The log line points to base-installer rather than live-installer as the cause. - - This is from the 16.04 server release ISO, running base-installer_1.158ubuntu2_amd64 and live-installer_51ubuntu2_amd64 + This is from the 16.04 server release ISO, running base- + installer_1.158ubuntu2_amd64 and live-installer_51ubuntu2_amd64 I would expect that locating the live-installer filesystem.squashfs would not prefix the specified URL with /cdrom. Previous versions of Ubuntu did not do this.
