I suspect something else is happening here, because ifup only reads
those files that consists only of a-z, A-Z, 0-9, _ and -. So files with
a tilde, whereever they appear in the filename, are ignored.
In order to find out what the real problem is, could you send me a copy
of your /etc/network/interfaces, /etc/network/interfaces.d/wlan0? Also,
do ifdown wlan0, and then run this command:
ifup -v wlan0 2>&1 >ifup.log
And send me a copy of ifup.log. You can of course also look at it
yourself, it should tell you exactly what ifup is trying to do and what
commands it is executing.
