reassign 555824 dpkg thanks Hi Guillem,
Firstly, this has nothing to do with cupt, I did the command manually. Where did you see 'cupt' in the report?

Again, this has nothing to do with any high-level package manager. -- Eugene V. Lyubimkin aka JackYF, JID: jackyf.devel(maildog)gmail.com C++/Perl developer, Debian Developer
