I'm having this problem with aptitude after a small poweroff.
This is what happened after aptitude update.
(Power went off right in the middle of aptitude update-ing).

Synaptic doesn't work as well.
Apt-get works fine.
Thank you Smile

apt-get update

if thats no good, run

apt-get clean && apt-get update

apt-get update --->

Czytanie list pakietów... Błąd!

aha... so it's the same. Except that aptitude update doesn't even display the first part
(till "Czytanie pakietów ...Błąd!" ---?> "Reading packages ...Error!").
Aptitude clean displays the same error.
When I run simply "aptitude" it displays the same thing .

What does Traf mean? something like Hit?

you should be able to try this (but I can't make any promises so back stuff up if its mission critical)

sudo rm /var/lib/apt/lists/* -vf

[gabriel_007]

That solved my problem, I was able to update and upgrade
Thank you qub333 for you help and attention
