Public bug reported: On Ubuntu 20.04, I found 'busybox hwclock -s' failed with "invalid argument" error, but hwclock of util-linux works well.
On bugzilla of busybox, there's someone reported the same/similar issue: https://bugs.busybox.net/show_bug.cgi?id=12756 $ apt policy busybox-static busybox-static: Installed: 1:1.30.1-4ubuntu6.1 Candidate: 1:1.30.1-4ubuntu6.1 Version table: *** 1:1.30.1-4ubuntu6.1 500 500 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 100 /var/lib/dpkg/status 1:1.30.1-4ubuntu6 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages $ sudo busybox hwclock -s hwclock: settimeofday: Invalid argument I tried to apply the patch on the bugzilla page, and it does resolve the issue. ** Affects: busybox (Ubuntu) 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/1888626 Title: hwclock -s fails with error: Invalid argument To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/busybox/+bug/1888626/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
