Quite likely what will happen is if the libc6-udeb is manually installed after it breaks and the install is continued on successfully, another failure will happen when the libnss-dns-udeb is pulled from the ubuntu archive, and will likely need to also be manually installed.
Hi, I've put test glibc packages in the ubuntu- security- proposed ppa https:/ /launchpad. net/~ubuntu- security- proposed/ +archive/ ubuntu/ ppa/+packages that revert the fix for CVE-2015-5180. If someone could test that the udeb's from there don't break your pxe install that would be great.
