Hi, I followed your instructions and installed 5.3.0-17.18+lp1846016. I didn't see any errors during boot just blinking cursor in left upper corner of display. However boot took probably same long time as when there were errors and, as I wrote, screen was black with blinking cursor instead of standard Ubuntu booting screen. I am attaching requested files
