Canonical has pulled Ubuntu 24.04.5's installer because it blew up when you tried an extended install

The TPMFDE files were removed, but the installer still referenced them, causing crashes. AMD64 download now serves 24.04.4; non-AMD64 images unaffected. Canonical to fix soon. The vast majority of OS bugs happen while it's running, but it's not unheard of for issues to strike before it can even get itself installed on your system. Such is the case with Ubuntu 24.04.5 Noble, which has had its AMD64 installer pulled because it would fail to install the OS whenever someone opted to perform an extended install. Ubuntu 24.04.5's installer has gone back to the workshop for further bug fixing It's a pretty nasty bug, to be fair As spotted by OMG Ubuntu, 24.04.5's installer had some TPMFDE support files removed from it. However, the installer still referenced the files, even though they were no longer there. This causes a problem when the installer tries to perform an extended install. As per the bug report: Underlying issues: * livecd-rootfs: in commit 7c77dd158b7728583bf8251c02ff6bce42b6dce0, part of the "enhanced-secure-boot" aka TPMFDE support was removed from the Noble ISOs. This means that the required files to do TPMFDE are mostly gone. Other references to "enhanced-secure-boot" are present, which leads subiquity to believe that TPMFDE is possible, kind of. * subiquity: while subiquity notices that the TPMFDE bits are not present, it falls back to non-TPMFDE incompletely. It should ignore the TPMFDE option entirely. As such, the company has pulled the 24.04.5 installer from their download page. If you try to download it, it will download 24.04.4 instead, despite the header for the page claiming you're getting 24.04.05. It's worth noting that other installers that aren't AMD64, such as the server edition, aren't affected. Here's hoping Canonical can fix it soon.
