Bug Description

Sorry I couldn't file this bug against the correct packages. The form told me there are no such packages as python-is-python3 and dh-python in Ubuntu...

Release: Groovy Gorilla (Ubuntu 20.10).

Package versions:
python-is-python3 3.8.2-4
dh-python 4.20200925

The release of Ubuntu 20.10 is less than two weeks out, so I'd like to draw attention to a problem I've run into. It seems that 20.10 defaults to python3 and wants to install python-is-python3, which pulls in the latest version of dh-python, which in turn can't co-exist with Oracle's Virtualbox-6.1 and wants to uninstall it.

I don't mind having _both_ python2 (apparently a requirement of VirtualBox) and python3 installed. But as of right now I can have either python-is-python3, and not be able to do a complete upgrade since virtualbox-6.1 will be uninstalled, or python-is-python2, in which case I cripple 20.10's python3 install, since I won't get dh-python and python-six.

Ia there something the python packagers do about this?

I'm sorry but I'm not following along with the issue you are describing. Could you please provide instructions so I can recreate the problem you are seeing? Additionally, are you using virtualbox from the official Ubuntu archive?

Additionally, python-is-python3 only depends on python3 and not dh-python as you've described.

I ran into the same problem. During dist-upgrade it wanted to remove python2 and virtualbox, but upgrade dh-python. The upgraded dh-python doesn't work with virtualbox.

I uninstalled dh-python, let dist-upgrade do what it wanted, then re-installed virtualbox, and that seemed to make everything happy.

Same issue: after upgrading from Ubuntu 20.04 to 20.10 my Virtualbox installation was missing (removed as part of the upgrade). Attempts to re-install indicated a conflict between the python pre-req and dh-python. I performed the following and all appears to be working now:

sudo apt remove dh-python
sudo apt install ./virtualbox-6.1_6.1.16-140961~Ubuntu~eoan_amd64.deb
sudo apt-get update
sudo apt-get upgrade

Still true of the deb packages provided by upstream for Virtualbox 6.1.18.

The problem is really with the packaging on their side which does not target ubuntu 20.10. In fact, they say so by indicating that they have a deb up to 19.10 and 20.04.

I guess there is little that ubuntu can do if Virtualbox does not want to package a deb for ubuntu 20.10 that is not an LTS. Most likely, they'll stick to 20.04 and start supporting newer ubuntu at 21.10 in preparation for the 22.04 LTS release.

On the other hand, I believe that ubuntu could help a lot here by making the current virtualbox always available in testing version on a PPA.
