Public bug reported: Ubuntu Customization Kit has not been maintained for years.
The Launchpad project page https://launchpad.net/uck tells: "!!!PROJECT DISCONTINUED!!!" Using UCK on current Ubuntu releases aborts with errors, e.g. because - the script tries to copy a file to itself (mtab) - gfxboot-theme-ubuntu_* is no longer provided as tar.gz, but as tar.xz archive. If you look at bugs and questions for the UCK prject (and uck on Ubuntu), you will see dozens of failure reports. Either repair uck on Ubuntu or remove it from Ubuntu 20.04! ** Affects: uck Importance: Undecided Status: New ** Affects: uck (Ubuntu) Importance: Undecided Status: New ** Tags: focal ** Tags added: focal ** Also affects: uck Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1864351 Title: Please remove uck from Ubuntu focal To manage notifications about this bug go to: https://bugs.launchpad.net/uck/+bug/1864351/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
