------- Comment From [email protected] 2015-03-17 17:43 EDT------- The "Invalid Release signature" is almost always a transient problem on whatever upstream mirror you happen to hit at the moment, or it is due to a mismatch between older netboot files and the latest upstream mirror. I'm guessing it won't be reproducible.
Here are the levels of the latest upstream repo and netboot installer. Below that is the md5sum of the latest netboot kernel & initrd. $ wget -qO- http://ports.ubuntu.com/dists/vivid/main/binary-ppc64el/Packages.bz2 | bunzip2 | grep linux-image | grep Filename Filename: pool/main/l/linux/linux-image-3.19.0-9-generic_3.19.0-9.9_ppc64el.deb Filename: pool/main/l/linux/linux-image-extra-3.19.0-9-generic_3.19.0-9.9_ppc64el.deb Filename: pool/main/l/linux-meta/linux-image-generic_3.19.0.9.8_ppc64el.deb Filename: pool/main/l/linux-meta/linux-image-virtual_3.19.0.9.8_ppc64el.deb $ wget -qO- http://ports.ubuntu.com/ubuntu-ports/dists/vivid/main/installer-ppc64el/current/images/netboot/ubuntu-installer/ppc64el/vmlinux | grep --text 'Linux version' Linux version 3.19.0-9-generic (buildd@fisher03) (gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu8) ) #9-Ubuntu SMP Wed Mar 11 17:50:43 UTC 2015 (Ubuntu 3.19.0-9.9-generic 3.19.1) $ wget -qO- http://ports.ubuntu.com/ubuntu-ports/dists/vivid/main/installer-ppc64el/current/images/netboot/ubuntu-installer/ppc64el/vmlinux | md5sum - 7e2c6811e17573923afafb6c8d443c56 - # wget -qO- http://ports.ubuntu.com/ubuntu-ports/dists/vivid/main/installer-ppc64el/current/images/netboot/ubuntu-installer/ppc64el/initrd.gz | md5sum - 40322bc97a70df0396b0f14354aff3cc - Please update your netboot files to the latest and see if the problem is reproducible.
