The ca-certificates fix for Xenial and Trusty include the changes to build the (new) udeb.
The normal deb package has been verified for regressions (next comments) and it is correct, with no functional changes whatsoever. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ca-certificates in Ubuntu. https://bugs.launchpad.net/bugs/1807023 Title: installer stock images fail to validate any HTTPS certificates (ca- certificates missing) Status in debian-installer: Unknown Status in ca-certificates package in Ubuntu: In Progress Status in debian-installer package in Ubuntu: In Progress Status in ca-certificates source package in Trusty: New Status in debian-installer source package in Trusty: New Status in ca-certificates source package in Xenial: New Status in debian-installer source package in Xenial: New Status in ca-certificates source package in Bionic: In Progress Status in debian-installer source package in Bionic: In Progress Status in ca-certificates source package in Cosmic: In Progress Status in debian-installer source package in Cosmic: In Progress Status in ca-certificates source package in Disco: In Progress Status in debian-installer source package in Disco: In Progress Status in debian-installer package in Debian: Fix Released Bug description: [Impact] * The installer stock images fail to validate any HTTPS certificates because ca-certificates is not available in the installer environment. * This causes wget/download errors for preseed files on HTTPS servers (or HTTP servers that redirect to HTTPS, which are increasingly common nowadays - e.g., GitHub) and theoretically any other files that are downloaded with d-i-utils/fetch-url/wget. * The fix is to ship ca-certificates-udeb in installer stock images. * Debian already ships ca-certificate-udeb in the stock installer images; the fix is applied since Jan 2017. (reference: Debian Bug #842040 / d-i commit 2f00c51a [1]) [Test Case] * In the installer shell: ~ # wget http://github.com # or https://github.com - FAIL if ca-certificates-udeb is missing: "ERROR: cannot verify github.com's certificate, <...>' - PASS if ca-certificates-udeb is available "Saving to: 'index.html'" * Test steps with virt-install and netboot images are provided in the comments, for each release. [Regression Potential] * Low. This just adds the ca-certificates files in /etc/ssl/certs and symlink in /usr/lib/ssl/certs, so only tools looking for that would be affected. * Apparently only wget checks for/uses those files, and the difference in behavior is download errors no longer occur. [Notes] * The ca-certificates-udeb is not currently present in the Ubuntu 'main' component, but in 'universe', despite the normal deb being in 'main'. However, when rebuilding in a PPA it goes into 'main' accordingly, and can be used by default by debian-installer (otherwise, UDEB_COMPONENTS has to be modified to include universe/d-i). * So this fix includes a no-change-rebuild for the ca-certificates package, in order to publish the udeb in the archive (at least in PPA for testing). Hopefully that can be sorted out for this fix to work out. * The ca-certificates and debian-installer builds have been done in a PPA using all architectures, and testing has been done with the amd64 images. * This fix is requested for Bionic, Cosmic, Disco at least. * The fix for Trusty and Xenial needed a little bit more work to build/ship the (new) udeb. (reference: Debian Bug #845456 / ca-certificates commit 3acb3a90 [2]) It would be good to have them too if at all possible.
