Reviewing the files from your upgrade attempt, you have installed packages from the deadsnakes PPA. Some of the packages installed are newer than those in the official archive, which is keeping some python packages installed which then prevents the upgrade from being calculated. Please try using the ppa-purge tool to remove packages installed from ppa:deadsnakes/ppa. After that you can try upgrading again and if it still fails open a new bug report. Thanks and good luck!

I have no luck with sudo ppa-purge ppa:deadsnakes/ppaLooks like OK
with sudo add-apt-repository --remove ppa:deadsnakes/ppaBut, still got
problem when sudo do-release-upgrade

~$ sudo add-apt-repository --remove ppa:deadsnakes/ppa This PPA
contains more recent Python versions packaged for Ubuntu.
Disclaimer: there's no guarantee of timely updates in case of security
problems or other issues. If you want to use them in a security-or-
otherwise-critical environment (say, on a production server), you do so
at your own risk.
Update Note===========Please use this repository instead of
ppa:fkrull/deadsnakes.
Reporting Issues================
Issues can be reported in the master issue tracker at:
https://github.com/deadsnakes/issues/issues
Supported Ubuntu and Python
Versions====================================
- Ubuntu 18.04 (bionic) Python2.3 - Python 2.6, Python 3.1 - Python
3.5, Python3.7 - Python3.11- Ubuntu 20.04 (focal) Python3.5 -
Python3.7, Python3.9 - Python3.11- Ubuntu 22.04 (jammy) Python3.7 -
Python3.9, Python3.11- Note: Python2.7 (all), Python 3.6 (bionic),
Python 3.8 (focal), Python 3.10 (jammy) are not provided by deadsnakes
as upstream ubuntu provides those packages.
Why some packages aren't built:- Note: for focal, older python versions
require libssl<1.1 so they are not currently built- Note: for jammy,
older python versions requre libssl<3 so they are not currently built-
If you need these, reach out to asottile to set up a private ppa
The packages may also work on other versions of Ubuntu or Debian, but
that is not tested or supported.
Packages========
The packages provided here are loosely based on the debian upstream
packages with some modifications to make them more usable as non-
default pythons and on ubuntu. As such, the packages follow debian's
patterns and often do not include a full python distribution with just
`apt install python#.#`. Here is a list of packages that may be useful
along with the default install:
- `python#.#-dev`: includes development headers for building C
extensions- `python#.#-venv`: provides the standard library `venv`
module- `python#.#-distutils`: provides the standard library
`distutils` module- `python#.#-lib2to3`: provides the `2to3-#.#`
utility as well as the standard library `lib2to3` module- `python#.#-
gdbm`: provides the standard library `dbm.gnu` module- `python#.#-tk`:
provides the standard library `tkinter` module
Third-Party Python Modules==========================
Python modules in the official Ubuntu repositories are packaged to work
with the Python interpreters from the official repositories.
Accordingly, they generally won't work with the Python interpreters
from this PPA. As an exception, pure-Python modules for Python 3 will
work, but any compiled extension modules won't.
To install 3rd-party Python modules, you should use the common Python
packaging tools. For an introduction into the Python packaging
ecosystem and its tools, refer to the Python Packaging User Guide:
https://packaging.python.org/installing/
Sources=======The package sources are available at:
https://github.com/deadsnakes/
Nightly Builds==============
For nightly builds, see ppa:deadsnakes/nightly

What happens when you run ppa-purge ppa:deadsnakes/ppa?

`apt-add-repository --remove` only removes the PPA sources, it does not remove packages that were installed from that PPA. In your case, you need to remove the python packages that were installed from the deadsnakes PPA. The ppa-purge tool is meant for that.

after reboot,system ask to upgrade many modules,will update you again
after finish all modules upgrade.

You may have to manually downgrade your python packages then, like:

$ apt install python3=<latest version from Ubuntu archive>

[adi sis (adisis23)]

~$ cat /etc/lsb-
release DISTRIB_ID=UbuntuDISTRIB_RELEASE=22.04DISTRIB_CODENAME=jammyDIS
