[Kubuntu] Problem z apt (python?)

Pozdravljeni!
KPackageKit je poskusil namestiti popravke in je bil pri tem neuspešen. Po ročnem zagonu apt-get update && apt-get dist-upgrade me čaka tole:

 Reading package lists... Done
 Building dependency tree
 Reading state information... Done
 You might want to run `apt-get -f install' to correct these.
 The following packages have unmet dependencies:
 python-newt: Depends: libnewt0.52 (= 0.52.2-11.3ubuntu3) but 0.52.2-11.3ubuntu3.1 is installed
 E: Unmet dependencies. Try using -f.
 

Zaženem sudo apt-get -f install in rezultat je tole:

 Preparing to replace python-newt 0.52.2-11.3ubuntu3 (using .../python-newt_0.52.2-11.3ubuntu3.1_amd64.deb) ...

Vse sem že poskusil (med drugim sem odprl tudi tole povezavo) pa ni rešitve na vidiku.

Imel sem tudi probleme z diskom (slabi sektorji, morda?), pa ne vem če je problem povezan. Res bo vsak nasvet dobrodošel. Tudi boljše mesto za tole vprašanje, če ne odgovora...
