I fixed it by using the same version from tutorials, try to download "crda-1.1.3.tar.bz2" and "wireless-regdb-2013.10.11.tar.bz2" instead.
Earlier this evening I ran into that error as well, but in Ubuntu Server 16.04 LTS. The error was confusing because even with an unmodified db.txt I got that error.
Turns out that error doesn't mean what it says. That error actually means it couldn't find regulatory.bin.
Please check where the regulatory.bin is being placed by the Makefile script from wireless-regdb and then check if crda's Makefile-script is looking in the right place.
In my case the regulatory.bin was being placed in /usr/lib/crda/ while crda was looking in /lib/crda/.
If the locations don't match, either edit wireless-regdb's or crda's Makefile-script. In the wireless-regdb Makefile-script, lines 2 and 3 are relevant:
Code:
PREFIX ?= /usr
CRDA_PATH ?= $(PREFIX)/lib/crda
In crda's Makefile-script lines 3, 6 (and in my case 25 too) are relevant:
Code:
REG_BIN?=/usr/lib/crda/regulatory.bin
PREFIX ?= /usr/
PUBKEY_DIR?=pubkeys
With the lines above, the locations are the same. But if you changed either one of them, or one of the two already contains a different default location, you need to make sure the other script gets changed as well.
