I have also tried this on ubuntu:20.10, ubuntu:20.04 and ubuntu:18.04 and it produces the same error there, too. I think it is an issue with the system clock reporting Jan 1st 1970. The system clock on the host system is correct though.
I could only find two ways to change the system clock in the ubuntu docker image: "date -s" requires --privileged (which isn't available in docker build) hwclock, which doesn't work on raspberry pi: root@8f7355a71bca:/# hwclock --verbose hwclock from util-linux 2.34 System Time: 0.-00001 Trying to open: /dev/rtc0 Trying to open: /dev/rtc Trying to open: /dev/misc/rtc No usable clock interface found. hwclock: Cannot access the Hardware Clock via any known method. other means like ntp don't work because they aren't preinstalled and cannot be installed because apt-get doesn't work (which is the topic of this bugreport) I was also not able to update libseccomp2, because wget and curl aren't preinstalled and cannot be installed either, because apt-get doesn't work. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libseccomp in Ubuntu. https://bugs.launchpad.net/bugs/1890332 Title: apt update fails on docker arm container 20.04 Status in libseccomp package in Ubuntu: Confirmed Bug description: Running `apt update` in a ubuntu:20.04 docker container on raspberry pi fails with GPG errors.
