Struggle to install LibreOffice on the PinePhone

[Peter Gamma]

So, the magical code to run LibreOffice in Posh on the PinePhone seems to be:

OOO_FORCE_DESKTOP=gnome-wayland libreoffice

I reeinstalled Posh, after I had and Ubuntu Toch on the Phone, and failed to install LibreOffice with Libertine, as I described above, and then stuck at the same step as above. I tried to type the magical line:

OOO_FORCE_DESKTOP=gnome-wayland libreoffice

I have connected a PinePhone keyboard to the phone, which works. But I cannot print a «_». It is on the keyboard, but neither control, Fn, Alt, AltG nor the special Pine key works to get the sign.

Also, there is no software keyboard there to type the magical line.

How can I type:

OOO_FORCE_DESKTOP=gnome-wayland libreoffice

on Posh, if LibreOffice seems to prevent the start of the GUI ?
