[Bug 1732030] Re: 'apt update' dies with seccomp error

[Julian Andres Klode]

Hi,

thanks for your bug report. It seems that something is trying to read a
directory. Could you perhaps run with apt::sandbox::seccomp::print set
to false and gather a stack trace and attach that here? (or let apport
do its magic and report it separately?). This would help figuring out
what needs that.

In the meantime, feel free to add 
  apt::sandbox::seccomp::allow { "getdents" };

to your apt.conf and try again (you can use scmp_sys_resolver to resolve
any other numbers to names and add them). Compared to just disabling it,
that would keep that sandboxing feature active :)
