OK, so I think we let this sit for a few more weeks and see what else we get. So far we have 4 people affected by this. Does not happen for me, BTW, and yes, I use the mirror method (from -proposed, the old one does not work and the new one is much better :D).
Now, as to documentation: There is not really supposed to be any. There's a NEWS entry for it telling you how to enable more syscalls for debugging, and it's listed in configure-index. But it's not something people should really configure in normal use. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1732030 Title: 'apt update' dies with seccomp error Status in apt package in Ubuntu: Confirmed Status in libvirt package in Ubuntu: Triaged Bug description: $ apt-get update 0% [Working] **** Seccomp prevented execution of syscall 0000000078 on architecture amd64 **** Reading package lists...
