Estou entendendo isso, você sabe de uma solução alternativa:
Errors were encountered while processing:
ubuntu-desktop
Error in function:
SystemError: E:Sub-process /usr/bin/dpkg returned an error code (1)
Error in sys.excepthook:
Traceback (most recent call last):

raise ValueError('%s does not exist' % self['ExecutablePath'])
ValueError: /usr/bin/python3.4 (deleted) does not exist
Original exception was:

Could not install the upgrades
The upgrade has aborted. Your system could be in an unusable state. A
recovery will run now (dpkg --configure -a).
dpkg: dependency problems prevent configuration of ubuntu-desktop:
ubuntu-desktop depends on ubuntu-session; however:
Package ubuntu-session is not installed.
ubuntu-desktop depends on unity-control-center; however:
Package unity-control-center is not installed.
ubuntu-desktop depends on unity-settings-daemon; however:
Package unity-settings-daemon is not installed.
dpkg: error processing package ubuntu-desktop (--configure):
dependency problems - leaving unconfigured
Errors were encountered while processing:
ubuntu-desktop
Upgrade complete
The upgrade has completed but there were errors during the upgrade
process.
Então, isso me impediu de fazer o login no X após a atualização, porque obviamente as dependências do ubuntu-desktop , como compiz , estavam quebradas.
Eu consertei indo para um shell de texto simples (Ctrl + Alt + F1) e, em seguida, seguindo esta solução com um pequeno ajuste:
sudo vi /etc/apt/apt.conf
# add this line: APT::Default-Release "vivid";
sudo apt-get -t vivid install apt/vivid
sudo apt-get update
sudo apt-get dist-upgrade
De acordo com Como posso corrigir E: Sub-processo / usr / bin / dpkg retornou um código de erro (2)?
