Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that there was an error caused by a corrupted archive. The corrupted packages are: libqalculate4 libcln5 libmarble4 ttf-bengali-fonts
Please execute the following commands, in a terminal ( Applications -> Accessories -> Terminal ) : sudo rm /var/lib/dpkg/info/{libqalculate4,libcln5,libmarble4,ttf-bengali-fonts}.{postinst,prerm,postrm} sudo apt-get remove --purge libqalculate4 libcln5 libmarble4 ttf-bengali-fonts sudo apt-get clean sudo apt-get update Then try performing the update again. This will likely resolve your issue. If so please set the bug's status to Invalid. Thanks in advance! ** Changed in: libqalculate (Ubuntu) Status: New => Incomplete -- package libqalculate4 0.9.6-3ubuntu1 failed to install/upgrade: subprocess installed post-removal script returned error exit status 2 https://bugs.launchpad.net/bugs/506638 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
