--------------- thunderbird (1:68.8.0+build2-0ubuntu0.18.04.2) bionic; urgency=medium [ Dariusz Gadomski ] * Disable reading /proc/sys/crypto/fips_enabled if FIPS is not enabled on build (LP: #1878155) -- Olivier Tilloy <olivier.til...@canonical.com> Wed, 13 May 2020 15:05:10 +0200 ** Changed in: thunderbird (Ubuntu Bionic) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial.

Download and install PSM and try again, or contact your system administrator. This seems to be a result of the fact that despite Thunderbird for Ubuntu being with FIPS support disabled there's a piece of code that ignores the build flag and checks for `/proc/sys/crypto/fips_enabled` status anyway. Looks like upstream fix [1] needs to be applied to Thunderbird source under security/nss. [Test Case] * Configure an email account in Thunderbird. I was able to reproduce it with a gmail account. * Install FIPS modules as described in [2]. * Boot into FIPS mode. * Open Thunderbird. [Regression Potential] * I can't identify regression potential - this is clearly a bug fixed upstream by a simple fix. [Other Info] * Related Firefox bug: https://bugs.launchpad.net/bugs/1843044 * I was able to backport this fix and test it - the problem was gone. Xenial build is available in ppa:dgadomski/thunderbird.
