Electrum 3.3.8 on a 32-bit Computer

After recently installing Lubuntu 18.04.3 LTS on my 32-bit computer, I have been trying to install Electrum 3.3.8 so far without success. My latest try consisted of

Code:

sudo apt-get update
sudo apt-get install python3-setuptools python3-pyqt5 python3-pip
wget https://download.electrum.org/3.3.5/Electrum-3.3.5.tar.gz
tar xvf Electrum-3.3.5.tar.gz

All appeared to work well (no error messages or warnings). I then tried to launch Electrum using Python.

Code:

python3 ~/Electrum-3.3.5/run_electrum
Traceback (most recent call last):
  File "/home/richard/Electrum-3.3.5/run_electrum", line 355, in
   fd, server = daemon.get_fd_or_server(config)
  File "/home/richard/Electrum-3.3.5/electrum/daemon.py", line 77, in get_fd_or_server
   remove_lockfile(lockfile)
  File "/home/richard/Electrum-3.3.5/electrum/daemon.py", line 58, in remove_lockfile
   os.unlink(lockfile)
PermissionError: [Errno 13] Permission denied: '/home/richard/.electrum/daemon'

I was at loss on what to do. I then got thinking about whether Electrum 3.3.8 is able to operate on a 32-bit computer, so before I go any further, is Electrum 3.3.8 designed to operate on a 32-bit computer under Lubuntu 18.04?
