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

Tue Dec 12 12:25:46 UTC 2017

I hit this today in a Bionic container trying to use "apt-get download".
Found this bug and based on this trying to provide the debug data that was requested back then.

So I gathered the crash file with JulianK's hint and then used Tamas
workaround to get all apport tools as needed.

# apport-retrace --rebuild-package-info --stdout /var/crash/_usr_lib_apt_methods_http.0.crash 
dpkg-source: info: extracting apt in apt-1.6~alpha5

W: Download is performed unsandboxed as root as file 'apt_1.6~alpha5.dsc' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)
