      I am on ubuntu 20.04. When I type instart], it take about 3 minutes to
      open the menu screen, then it says
      gscan2pdf: sane_start: Error during device I/O
      I even reinstalled sane manually. but it still doesn’t work.
      Please help.

      I am using gscan2pdf 2.8.0 on ubuntu 20.04. When I launch [gscan2pdf],
      it take almost a minute to open the menu screen. After scanning one page,
      it just skips all the rest. Then it says
      gscan2pdf: sane_start: Operation was canceled
      and quit. It used to work well on 18.04.
      Please help.

      Apparently, I had a script named [gm] in my personal /bin, and it interacted with gscan2pdf.
      I removed [gm], and the GUI comes out instantly. Sorry about unnecessary confusion.
      But skipping all the sheets after the first one persists. In fact, that behavior is the same to
      “simple-scan”.
      The following error message may be related to this error:
      “gscan2pdf: sane_start: Operation was canceled”
