Impact
------
Users with the package python-dbg installed on their system are unable to upgrade from Ubuntu 18.04 LTS to Ubuntu 20.04 LTS as the upgrade path is not calculable.
Test Case
---------
1) On an Ubuntu 18.04 LTS system install python-dbg (or some set of packages which depend on it)
2) Run do-release-upgrade
3) Observe a message regarding a failure to calculate the upgrade
With the dist-upgrader from -proposed there will be no such failure to calculate the upgrade.
Regression Potential
--------------------
The logic of the "_install_python_is_python2" quirk is essentially the same but the set of replacements is being expanded so we should ensure that this does not cause any additional package removals which may are unwanted.

Impact
------
Users with the package python-dbg installed on their system are unable to upgrade from Ubuntu 18.04 LTS to Ubuntu 20.04 LTS as the upgrade path is not calculable.
Test Case
---------
1) On an Ubuntu 18.04 LTS system install python-dbg (or some set of packages which depend on it)
2) Run do-release-upgrade
3) Observe a message regarding a failure to calculate the upgrade
With the dist-upgrader from -proposed there will be no such failure to calculate the upgrade.
Regression Potential
--------------------
The logic of the "_install_python_is_python2" quirk is essentially the same but the set of replacements is being expanded so we should ensure that this does not cause any additional package removals which may are unwanted.

Impact
------
Users with the package python-dbg installed on their system are unable to upgrade from Ubuntu 18.04 LTS to Ubuntu 20.04 LTS as the upgrade path is not calculable. Additionally, other python packages from Ubuntu 18.04 will be left installed or removed when they should not be.
Test Case
---------
[python-dbg]
1) On an Ubuntu 18.04 LTS system install python-dbg (or some set of packages which depend on it)
2) Run do-release-upgrade
3) Observe a message regarding a failure to calculate the upgrade
With the dist-upgrader from -proposed there will be no such failure to calculate the upgrade.
[python-doc]
1) On an Ubuntu 18.04 LTS system install python-doc
2) Run do-release-upgrade
3) Say Y to removing obsolete packages
4) Observe that python-doc is still installed on the system
With the version of the dist-upgrader from -proposed python-doc will not be installed after the upgrade and python2-doc will be.
[python-dev]
1) On an Ubuntu 18.04 LTS system install python-dev
2) Run do-release-upgrade
3) Say Y to removing obsolete packages
4) Observe that python-dev is still installed on the system
With the version of the dist-ugprader from -proposed python-dev will not be installed after the upgrade and python2-dev will be installed. Additionally, python-dev-is-python2 will be installed.
Regression Potential
--------------------
The logic of the "_install_python_is_python2" quirk is essentially the same but the set of replacements is being expanded so we should ensure that this does not cause any additional package removals which may are unwanted.

---------
[python-dbg]
1) On an Ubuntu 18.04 LTS system install python-qt4-dbg (or some set of packages which depend on it)
2) Run do-release-upgrade
3) Observe a message regarding a failure to calculate the upgrade
With the dist-upgrader from -proposed there will be no such failure to calculate the upgrade.
[python-doc]
1) On an Ubuntu 18.04 LTS system install python-doc
2) Run do-release-upgrade
3) Say Y to removing obsolete packages
4) Observe that python-doc is still installed on the system
With the version of the dist-upgrader from -proposed python-doc will not be installed after the upgrade and python2-doc will be.
[python-dev]
1) On an Ubuntu 18.04 LTS system install python-dev
2) Run do-release-upgrade
3) Say Y to removing obsolete packages
4) Observe that python-dev is still installed on the system
With the version of the dist-ugprader from -proposed python-dev will not be installed after the upgrade and python2-dev will be installed. Additionally, python-dev-is-python2 will be installed.
Regression Potential
--------------------
The logic of the "_install_python_is_python2" quirk is essentially the same but the set of replacements is being expanded so we should ensure that this does not cause any additional package removals which may are unwanted.
Original Description
--------------------
the problem is during issue this command from terminal to start upgrade

Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade.
This was caused by:
* Upgrading to a pre-release version of Ubuntu
This is most likely a transient problem,
please try again later.
If none of this applies, then please report this bug using the
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If
you want to investigate this yourself the log files in
'/var/log/dist-upgrade' will contain details about the upgrade.
Specifically, look at 'main.log' and 'apt.log'.
