was not found in the database provided by tcell library. Please try checking if
a supplemental database is found for your terminal at one of the following URLs:
        https://github.com/gdamore/tcell/raw/master/terminfo/database/98/98d2a8a0
        https://github.com/gdamore/tcell/raw/master/terminfo/database/98/98d2a8a0.gz
If yes, download it and save in the following directory:
        $HOME/.tcelldb/98/
then try running "up" again. If that does not work for you, please first consult:
        https://github.com/akavel/up/issues/15
and if you don't see your terminal code mentioned there, please try asking on:
        https://github.com/gdamore/tcell/issues
Or, you might try changing TERM temporarily to some other value, for example by
running "up" with:
        TERM=xterm up
Good luck!```
