[Bug 1875523] Re: I can't upgrade the ubuntu to 20.04 by terminal. Everytime I do it, a message appear saying that it is not possible do the upgrade.

[Brian Murray]

** Description changed:

- You look. I can't explain about it in english, but it is here the
- message. I hope you can understand it.
+ Impact
+ ------
+ Some upgrades from Ubuntu 18.04 LTS to Ubuntu 20.04 LTS fail to calculate which prevents people from upgrading to Ubuntu 20.04 LTS.
  
+ Test Case
+ ---------
+ 1) install pyhton-pyside and python-gi on an up to date Ubuntu 18.04 LTS system
+ 2) run do-release-upgrade -d
+ 3) Observe the upgrade fail to calculate an upgrade to Ubuntu 20.04 LTS
  
- Não foi possível calcular a atualização 
+ To test the version of the dist-upgrader from -proposed you'll need to
+ download the dist-upgrade tarball and extract it in to /tmp/. Then run
+ sudo ./focal --frontend DistUpgradeViewText.
  
- Ocorreu um problema sem solução, enquanto estava calculando a 
- atualização. 
+ Regression Potential
+ --------------------
+ Given that the release upgrader is replacing python-minimal with python-is-python2 we should ensure that python-is-python2 is installed after the upgrade. We should also test an upgrade from Bionic to Focal which calculated successfully with the existing version of the release upgrader.
  
- Isto foi causado por: 
- * Atualiza para a versão de pre-lançamento do Ubuntu 
- Isto deve de ser provavelmente um problema transitório, 
- por favor tente novamente mais tarde. 
- Se nada disto servir, então por favor comunique a falha usando o 
- comando 'ubuntu-bug ubuntu-release-upgrader-core' no terminal. Se 
- você quiser investigar isto por si os ficheiros de registro em 
- '/var/log/dist-upgrade' contém detalhes sobre a atualização. Olhe
