Hi Cryolithe, I know that glibc changed things in 2.31 but I thought that is in proposed still. I was working (I thought just for test/build issues) on an update in bug 1866753. It does internal syscall filtering and that changed in glibc. Out of that I already have PPA: https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/3968 Soon that will show up in focal-proposed anyway, but still.
@Cryolithe - would you mind trying if that PPA resolves it for you and report back here? - Also are you running -proposed enabled? - And anyway the report lacks some data - which Ubuntu release are you running atm? $ cat /etc/os-release $ apt-cache policy chrony It would also be great to run apport to get the package upgrade history and all that right away. $ apport-collect 1867036 Finally maybe we should check and compare caps in your system $ apt install libcap-ng-utils $ pscap -a # if the service didn't fail but keeps running with reduced caps Example output on a container: root@f:~# pscap -a | grep chrony 1 26441 _chrony chronyd net_bind_service 26441 26442 _chrony chronyd net_bind_service Example output on a VM: @f $ pscap -a | grep chrony 1 1707 _chrony chronyd net_bind_service, sys_time + 1707 1708 _chrony chronyd net_bind_service, sys_time + ** Changed in: chrony (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1867036 Title: Focal Fossa : chronyd unable to sync system clock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chrony/+bug/1867036/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
