Hi, the package dropbear.tcz 64bit (but possibly the others architectures too) has within the absolute links.
This means that ssh is a link to /usr/local/bin/dropbearmulti instead of being a link to dropbearmulti.
Others packages has relative links that allows binaries relocations but not this one.
I suggest to fix it and implement a check to avoid using absolute links in the packages.
Thank you, R.
