Sul mio Kubuntu 14.4 (che ha Python 2.7.6 come standard) il mio Python si è rotto dopo aver provato a installare Python 2.7.10 dopo aver compilato dal sorgente da python.org con l'aiuto di Come installare l'ultima versione di Python su Debian separatamente o l'aggiornamento? . Non sono in grado di ripararlo con i comandi standard che sospetto che il mio dpkg sia in qualche modo confuso / rotto per quanto riguarda l'installazione di Python. Vorrei correggere dpkg in questo aspetto. Ho il sospetto che questo ha qualcosa a che fare con il file /var/lib/dpkg/statused /var/lib/dpkg/availablee /var/lib/dpkg/info/*particularily il primo. Penso di dover ripristinare in dpkgqualche modo, ma non sono davvero un esperto. Il motivo per cui penso che questo sia:
$ apt-cache policy python

Il motivo per cui ho provato ad installare Python 2.7.10 è perché ne avevo bisogno per un altro programma (a causa di problemi con ssl / openssl di Python 2.7.6), ma ora voglio solo riparare il mio sistema - lascia che sia Python 2.7 .6.
Il tecnico completo
Ho iniziato a provare a risolvere questo problema chiedendo su Ubuntu /ubuntu/648424/muon-is-gone-after-change-of-python-issues-after-python-2-7-10-installation- su , ma non ho avuto alcuna risposta c'è. Forse era la folla sbagliata. Da allora ho provato un bel po 'e ho un'idea del problema, ma non conosco i passaggi per farlo.
È iniziato con me non riuscire a installare muon con sudo apg-get install muon:
$ sudo apt-get install muon

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
muon : Depends: apt-xapian-index but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I consigli tipici (ad es. Da /ubuntu/118749/package-system-is-broken-how-to-fix-it ) non aiutano:
sudo apt-get autoremove
sudo apt-get clean
sudo apt-get autoclean
sudo apt-get update
sudo apt-get upgrade -f
sudo apt-get -f install muon
o
sudo apt-get -f installo
sudo dpkg --configure -a
sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get install muon
o
sudo apt-get -o dpkg::options::="--force-confnew" -o dpkg::options::="--force-confmiss" --reinstall install muonnon ha aiutato. Quindi ci ho provato
$ sudo apt-get install apt-xapian-index

e ho scoperto che il problema riguarda anche altri programmi
$ sudo apt-get install meld

Quindi ho provato (senza fortuna)
$ sudo update-alternatives --config python
update-alternatives: error: no alternatives for python
Neanche questo ha aiutato:
sudo dpkg -P python2.7
sudo apt-get install python2.7
sudo dpkg -P python-minimal
sudo apt-get autoremove && sudo apt-get clean sudo apt-get update && sudo apt-get -f install
Sto ottenendo

La prossima volta che vuoi compilare e installare Python dal sorgente, potrebbe essere una buona idea installarlo in una posizione alternativa (prima). Python è presente sul tuo sistema come parte dello stack software utilizzato da altre applicazioni. È un po 'pericoloso installarlo sull'installazione Python a livello di sistema senza testarlo. È possibile impostare il percorso di installazione fornendo

./configure --prefix=/opt/python. In caso contrario, potrebbe essere stato dove le cose sono andate male. Senza fornire la --prefix=/opt/pythonparte, è possibile sovrascrivere l'installazione a livello di sistema. Hai seguito esattamente queste istruzioni?
