Closed leggewie closed 8 years ago

I was able to dedupe files successfully in the past. But today whenever I run duperemove it ends with an error.

$ sudo duperemove -hrd --hashfile /tmp/duperemove.hashes /var/lib/lxc/

This is on Ubuntu trusty, kernel 3.13.0-95-generic

Turns out this is actually an incompatibility with the i386 binary when running an amd64 kernel (32 vs 64 bit). I think this was a false report and can be safely closed. FWIW, lsattr (32 bit) had the same problem.
