unmet dependencies when installing PyQt5 on ubuntu

Question

installing pyqt5 on ubuntu gives the following error messages:

sudo apt-get install python3-pyqt5
...
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libpython3.10 : Depends: libpython3.10-stdlib (= 3.10.4-1+focal2) but 3.10.3-1+focal1 is to be installed
 libpython3.10-dev : Depends: libpython3.10-stdlib (= 3.10.4-1+focal2) but 3.10.3-1+focal1 is to be installed
 python3-pyqt5 : Depends: libqt5core5a (>= 5.12.4) but it is not going to be installed
                 Depends: ....
 python3.10 : Depends: libpython3.10-stdlib (= 3.10.4-1+focal2) but 3.10.3-1+focal1 is to be installed
 python3.10-minimal : Depends: libpython3.10-minimal (= 3.10.4-1+focal2) but 3.10.3-1+focal1 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I tried to solve the issue with the following code that shows the results.

sudo apt --fix-broken install
...

Run the below commands to clear any issues then try again.

apt-get check
apt-get --fix-broken install
dpkg --configure -a
apt-get autoremove -y
apt-get autoclean 
apt-get clean 

Then remove the broken python files

sudo dpkg --remove --force-all libpython3.10-minimal libpython3.10-stdlib 
sudo apt install libpython3.10-minimal libpython3.10-stdlib 
sudo apt-get install python3-pyqt5
