The not-child extension is supported in fwupd 1.2.7 and later (https://github.com/fwupd/fwupd/commit/b62c3a4fae1104c4a1052adc7b3196afa8c33307). Ubuntu 18.04 currently contains fwupd 1.2.5.
There is currently an SRU in process to update to 1.2.10 as part of bug 1820768. This issue will be closed by that SRU upgrade as well. So your options are: 1) Wait for that SRU to complete. 2) Switch to a newer version of Ubuntu with a newer fwupd 3) Switch from deb packaged fwupd to snap packaged. See https://github.com/fwupd/fwupd/wiki/fwupd-snap for more information on switching to the snap. ** Also affects: fwupd (Ubuntu Focal) Importance: Undecided Status: Incomplete ** Also affects: fwupd (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: fwupd (Ubuntu Disco) Importance: Undecided Status: New ** Changed in: fwupd (Ubuntu Disco) Status: New => Triaged ** Changed in: fwupd (Ubuntu Bionic) Status: New => Fix Committed ** Changed in: fwupd (Ubuntu Focal) Status: Incomplete => Fix Released ** Changed in: fwupd (Ubuntu Bionic) Importance: Undecided => Low ** Changed in: fwupd (Ubuntu Focal) Importance: Undecided => Low ** Changed in: fwupd (Ubuntu Disco) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773307 Title: Update for Logitech Unifying Receiver offered but cannot be updated To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fwupd/+bug/1773307/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
