well, i still highly doubt that this binary comes from an archive
package, the archive upload checks would have refused to let such a
package in and looking at the archive package (in either 16.04 or
18.04) i get:

$ dpkg -L aircrack-ng|grep bin/aircrack
/usr/bin/aircrack-ng

note that /usr/local/bin comes before /usr/bin in the PATH variable for
the above reasons (to allow the admin to override packaged binaries
with local builds from source). so even if you would install the
archive package the binary from /usr/local will still be used until you
completely remove it there ...
