You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 codeblocks-contrib : Depends: libboost-system1.62.0 but it is not installable
                      Depends: libhunspell-1.4-0 but it is not installable
                      Depends: libwxgtk3.0-0v5 (>= 3.0.2+dfsg) but it is not installable
                      Depends: libwxsmithlib0 (= 20.03) but 20.03-3 is to be installed
                      Depends: codeblocks (= 20.03) but it is not going to be installed
                      Recommends: valgrind but it is not going to be installed
                      Recommends: cppcheck but it is not going to be installed
                      Recommends: cscope but it is not going to be installed
                      Recommends: cccc but it is not going to be installed
 codeblocks-dev : Depends: libcodeblocks0 (= 20.03) but 20.03-3 is to be installed
 codeblocks-libwxcontrib0 : Depends: libwxgtk3.0-0v5 (>= 3.0.2+dfsg) but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I suggest you do the following commands that might install the software and remove the error message

sudo apt --fix-broken install

sudo apt update

sudo apt-get upgrade

sudo apt install codeblocks

Step 1:

Firstly I would suggest trying the whole installation procedure using aptitude, since it provides solutions that most of the time work.

sudo apt update
sudo apt install aptitude    

And then try downloading your package using aptitude:

sudo aptitude install <package-name>

Step 2:

If that doesn't work, try downloading the dependencies one by one to see if the problem goes away.

sudo apt install -f libcodeblocks0=20.03 # -f flag means fix broken
sudo apt install -f libwxgtk3.0-0v5=3.0.2+dfsg
sudo apt install -f libboost-system1.62.0
sudo apt install -f libhunspell-1.4-0
sudo apt install -f libwxsmithlib0=20.03

Step 3:

If the above steps don't cut it either (which I guess might happen since some packages are marked as not installable), try downloading those packages from Ubuntu registry for your computer architecture (I'll list for amd64)

Links:

libwxgtk3.0-0v5

codeblocks

libcodeblocks0

libhunspell-1.4-0 (right, under downloadable files)

libwxsmithlib0

libboost-system1.62.0

Hope this solves the problem. If not, comment below.
