For what its' worth, the Focal system's provided packages do not meet the following build-deps of the *debian* Thunderbird 91.3.0 package;-
cbindgen (>= 0.19) debhelper-compat (= 13) libnspr4-dev (>= 2:4.32~) libnss3-dev (>= 2:3.68~) nodejs (>= 10.19.0) Merely overriding the version dependencies in debian control file [which can just automatically referring to latest version needlessly] is not sufficient, an internal check *actually* requires e.g. nspr >=4.32 . These packages may need backporting or whatever, or the ubuntu packages may work differently to get around these limitations for building (in any case build-deps and runtime-deps may be another matter...). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1949605 Title: Backport Thunderbird 91 to 20.04 LTS and 18.04 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1949605/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
