It looks like you were running the package manager more than once, or perhaps interrupted it from a previous run.
This problem is closely related to your dpkg lock. $ sudo lsof /var/lib/dpkg/lock-open If that shows no output, then you may remove that file. Then, $ sudo apt-get clean Then, install as normal. ** Changed in: chromium-browser (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1274383 Title: package chromium-browser (not installed) failed to install/upgrade: cannot copy extracted data for './usr/lib/chromium- browser/libs/libicuuc.so' to '/usr/lib/chromium- browser/libs/libicuuc.so.dpkg-new': unexpected end of file or stream To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1274383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
