Following the guide Signing Builds for Release, I'm trying to sign a target file with my own keys, I ran the command below:

./build/tools/releasetools/sign_target_files_apks \
    -o \
    -d ~/.android-certs \
    target_files-20161102.zip \
    signed-target_files-20161102.zip

failed with:

It seems like I don't have access permission to /tmp/targetfiles-wqUF1M/BOOT/RAMDISK/file_contexts, chown -R myron:myron /tmp didn't solve the problem.
