Hello,

I had the same problem. The cause were some old libs in 
/lib/x86_64-linux-gnu, especially a libseccomp. They are not 
package-managed (i.e. they don't belong to any package). I have copied 
them manually from /usr/lib/x86_64-linux-gnu to /lib/x86_64-linux-gnu 
some time ago. The new libseccomp2 package shipped new binaries to 
/usr/lib/x86_64-linux-gnu but the runtime loader loaded the old version 
in /lib/x86_64-linux-gnu.

The problem disappears if either I remove the old libs from 
/lib/x86_64-linux-gnu or if I copy the new binaries from 
/usr/lib/x86_64-linux-gnu to /lib/x86_64-linux-gnu.

HTH,
Sorin
