Thank you for taking the time to report this bug and helping to make Ubuntu better.
By filing this bug against `ubiquity`, you've reported an issue against the desktop installer, and details gained by the apport tool were geared at exploration of your installer issues. I've changed the filing to be against the kernel (ie. linux) however it may still be difficult for any exploration given the reported detail includes almost no kernel details (instead getting installer details) ** Package changed: ubiquity (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1987996 Title: boot is failing shows error ACPI BIOS error (bug): could not resolve symbol [\_SB.PR00._CPC] I tried reinstalling ubuntu and erase the current files however the installer crashed.
