With pip and python you have installed the Python version 2 of spacy. This isn't supported any longer, and it's not surprising that you have problems. Use Python version 3:
pip3 install spacy

Well, I have no idea why or how this was the issue, but following the advice of another post, changing host in server.py to '' fixed it.

Your LED might be turning off when the end of the script is reached, for example the following script will turn the LED on for 5 seconds, then end, and restore the pin back to its original state (LED off):
from gpiozero import LED
from time import sleep
led = LED(5)
led.on()
sleep(5)
In order to keep the LED on indefinitely, the script must be kept alive. ...

Agustina, my classmate, pointed out the mistake.
def reset(self):
global started
global belowLow
global seconds
self.t.set(0)
started = False
seconds = 0
belowLow = 0
self.listen() <-- should not be included
Because of self.listen() it was recursing. I hope I am using the correct term.

No. Do not install it in /usr/bin. /usr/bin is for programs installed by the package manager. If you install packages manually, they go in /usr/local/bin (or ~/.local/bin etc.).
You can use the --prefix option of the configure script to select the folder to install it to, by default the prefix is /usr/local. As mentioned in (1), don't set it to /usr or you'...

sudo apt install ca-certificates

Rather than the rather bizarre steps you followed, most of which are unnecessary and possibly damaging I suggest you restore a clean Ubuntu and utilise the included Python.
Then download the official tarball https://pypi.org/project/RPi.GPIO/#files
Then follow the instructions included, viz.
$ sudo apt-get install python-dev python3-dev
To install the ...

You can use simple timers to have full control about the time and switches. Just create a service that will switch the lights and create two timer, one to switch on and one to switch off the lights. First create the service:
rpi ~$ sudo systemctl edit --force --full switch-lights@.service
In the empty editor insert these statements, save them and quit the ...

Use pigpio.
#!/usr/bin/python3
import pigpio
GPIO_ENCHUFE = 27
pi = pigpio.pi()
level = pi.read(GPIO_ENCHUFE)
if level == 0:
pi.write(GPIO_ENCHUFE, 1)
else:
pi.write(GPIO_ENCHUFE, 0)
pi.stop()

I like simple. This is how I'd do it:
crontab -e
In your editor, add the following lines to your crontab:
@reboot /bin/sleep 30; /usr/bin/gpio -g mode 17 out
0 18 * * * /usr/bin/gpio -g write 17 1
0 1 * * * /usr/bin/gpio -g write 17 0
Save your crontab, and exit the editor. At 6:00 PM (your RPi time), GPIO 17 (pin 11) will go "HIGH"; i.e. the ...
