Prosody was unable to find LuaSec?!

[ip...@posteo.de]

Hi at all,

Prosody was unable to find LuaSec?!

System Information:
# uname
Linux raspberrypi 4.14.39-v7+ #1112 SMP Sat May 5 12:01:33 BST 2018
armv7l GNU/Linux

On startup:
"Hello and welcome to Prosody version 0.10.0"
"Prosody was unable to find LuaSec"
in log: "Error creating context ... LuaSec (required for encryption) was
not found"

but it is installed?!
# apt list lua-sec prosody
lua-sec/oldstable,now 0.5-1 armhf [installiert]
prosody/oldoldstable,now 0.10.0-1~wheezy4 armhf [installiert]

Whats wrong?

Bests! Lars

Hi Lars,

It may be found, but there may be some problem loading it. You can see
by running:

lua5.1 -e 'print(require"ssl" and "ok")'

> Whats wrong?

The above command should give more info. But I suspect it is probably
caused by mixing lua-socket and lua-sec from different sources, which
can happen during dist upgrades.

Make sure both of the packages you have installed come from the same
repository. Compare `apt policy lua-sec` with `apt policy lua-socket`.
Often the fix is just as simple as reinstalling the package using apt
install --reinstall.

Hope this helps.

Regards,
Matthew

Wow, the chef himself ...

Hi Matthew,

I don't know what to make of this.

and this one (lua-socket) is the issue. See how the installed version
ends with ~wheezy? But you're on Jessie. And it doesn't have an apt
repo associated with it. Reinstall it so you get the other version,
3.0~rc1-3 from your raspbian repo. Then all should work!

Matthew
