Places to check: /etc/apt/apt.conf.d/10periodic Look for "APT::Default-Release" line.
Check your /etc/apt/sources.list file. Does that term appear there? After an update, my sources.list was mass-changed from "oneiric" to "precise". But I haven't upgraded the system to precise yet. (At least, the system doesn't think so.) In sources.list, I copied the top two lines that read: deb http://us.archive.ubuntu.com/ubuntu/ precise main restricted deb-src http://us.archive.ubuntu.com/ubuntu/ precise main restricted and edited them to say: deb http://us.archive.ubuntu.com/ubuntu/ oneiric main restricted deb-src http://us.archive.ubuntu.com/ubuntu/ oneiric main restricted Then, update-manager offered a "Partial upgrade". Not quite working, but appears to be progress. I suppose one could also try changing the APT::Default-Release from "oneiric" to "precise", too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/978821 Title: E: Значение «oneiric» недопустимо для APT::Default-Release, так как выпуск недоступен в источниках E: _cache->open() failed, please report.
