This is a problem with libneon27 in Ubuntu bionic itself, not a problem with Launchpad. In a clean chroot:
(bionic-amd64)root@niejwein:~# apt install libneon27 Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libneon27 : Depends: libssl1.1 (>= 1.1.1) but it is not going to be installed E: Unable to correct problems, you have held broken packages. In other words, somebody published the neon27 update for OpenSSL 1.1.1 without the corresponding OpenSSL 1.1.1 update that it depends on. I guess this will be resolved once https://launchpad.net/ubuntu/+source/openssl/1.1.1-1ubuntu2.1~18.04.1 is published to bionic-updates, but I'm subscribing a couple of people involved with the update anyway since this seems like a significant process failure. ** Project changed: launchpad-buildd => neon27 (Ubuntu) ** Also affects: neon27 (Ubuntu Bionic) Importance: Undecided Status: New ** No longer affects: neon27 (Ubuntu) ** Changed in: neon27 (Ubuntu Bionic) Status: New => Triaged ** Changed in: neon27 (Ubuntu Bionic) Importance: Undecided => Critical -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832077 Title: libneon27-dev builddep can not be installed in recipebuild To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/bionic/+source/neon27/+bug/1832077/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
