You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libgd3 : Breaks: libgd3:i386 (!= 2.2.5-4ubuntu0.2) but 2.2.5-4ubuntu0.4 is to be installed
libgd3:i386 : Breaks: libgd3 (!= 2.2.5-4ubuntu0.4) but 2.2.5-4ubuntu0.2 is to be installed

Depends: libpython3.7-stdlib (= 3.7.5-2~18.04.4) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
When I tried apt --fix-broken install.. I got this:
$ apt --fix-broken install
E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?
Please help me to fix this!
Edit: the version of my system is:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.5 LTS
Release: 18.04
Codename: bionic
The errors I got after using sudo apt --fix-broken install are:
