Domoticz

Hi, i need some help to cleanup my buster installation mistakes with motion...
I already installed: buster, domoticz, apache, dashticz, hue, broadlink, mqtt and nodered. All seems to work ok on Buster.
Troubles came with the last software: motion.. all my mistake because off bad reading.....

My first attempt:
---------------------
a. sudo wget https://github.com/Motion-Project/motio ... _armhf.deb
b. sudo apt-get install gdebi-core
c. sudo gdebi pi_stretch_motion_4.2.2-1_armhf.deb

then i get an error:
sudo gdebi pi_stretch_motion_4.2.2-1_armhf.deb
Reading package lists... Done

Reading state information... Done
Dit pakket is niet installeerbaar
Dependency is not satisfiable: libavcodec57 (>= 7:3.2.12)|libavcodec-extra57 (>= 7:3.2.12)

My second attempt (read on the internet)
---------------------------------------------------
a. sudo apt install motion
that works, but is an old version and i only have new configfiles !

Third attempt
-----------------
I read that there is a Buster package!
https://github.com/Motion-Project/motio ... _armhf.deb

So on my thirst step i had to do
a. sudo wget https://github.com/Motion-Project/motio ... _armhf.deb
b. sudo apt-get install gdebi-core
c. sudo gdebi pi_buster_motion_4.2.2-1_armhf.deb

Question:

How can i remove the actions from my first two attempts ?
So that i can start/try the third attempt

solved:

sudo apt-get remove motion
