Finally I resolved this problem using boot-repair. These above error disappeared (E: Sub-process /usr/bin/dpkg returned an error code (1) ) but still loks like installation is incomplete. Any application using Qt5 have does't start*, although I had installed Qt like this: sudo apt-get install qt5-*
* Eg: qtractor: error while loading shared libraries: libQt5Widgets.so.5: cannot open shared object file: No such file or directory -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772008 Title: grub instalation crashed (2nd time) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1772008/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
