Error while installing luajwtjitsi

I am trying to get information about rooms from the server. I have enabled “muc_size” module in the /etc/prosody/conf.d/localhost.cfg.lua and configured nginx. I am getting 404 error. My prosody log is like this:

I tried to install luajwtjitsi using luarocks-5.2, but it depends on luacrypto which gives a lot of error while installing. What should I do to avoid these errors? @saghul @damencho

I have some notes on installing those let me paste it here, probably it will help you:

"apt-get install liblua5.2-dev
wget https://keplerproject.github.io/luarocks/releases/luarocks-2.4.1.tar.gz
./configure --lua-version=5.2 --versioned-rocks-dir
make build
sudo make install
luarocks-5.2 install net-url"
luarocks-5.2  install basexx
apt-get install libssl1.0-dev
luarocks-5.2  install luajwtjitsi
luarocks-5.2  install lua-cjson 2.1.0-1

Thanks a lot for your help. It worked.

Now I am facing a different issues. Whenever I query for room-size with a room name it returns 404(room doesn’t exist) even if there is already a room with that room name.

While debugging, I saw that get_room_from_jid() function always returns nil.

What am I missing?

What is value you pass to get_room_from_jid?
Is it room@conference.mydomain.com?

Yes and also it worked after waiting for 5 minutes. Thanks a lot for your help.

This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘libssl1.0-dev’ has no installation candidate

not able to install libssl1.0-dev. When trying to install luajwtjitsi it asks for crypto. Please suggest

further
libssl-dev is already the newest version (1.1.1c-1ubuntu4).
