I am on Ubuntu 18.04LTS. When I run sudo apt update, the result shows 4 packages can be upgraded. Run 'apt list --upgradable' to see them.
But, when I run sudo apt upgrade it shows
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded
When I run sudo apt dist-upgrade or sudo apt full-upgrade it shows the same result. I found this question and could not find the answer why the packages not upgraded.How to resolve this?

When try to manually install packages it shows this error

I cannot answer why this is happening but there are a few things you can do to either resolve the issue or upgrade the packages to the newest version.
First, run the following command to clear your cache and upgrade:
If that does not work, run the following commands to explicitly install the packages (however, be careful to read the changes before you accept the changes because the system may want to uninstall some packages and this may not be what you want to do):
Now, if you run into an impossible situation or if there is a problem with dependencies, please edit your question and post the errors. Thanks!
UPDATE
Run the following command to see what version of python3 is installed and then try the installation again:
If you still have the problem it is because the ppa or extra repository you are using has not published the required version of python3 yet. Most likely, the extra version will be available soon.
