lnav 0.9.0 gives following error `Error opening terminal: screen.xterm-256color.`

[xuoguoto]

lnav version Using v0.9.0 under Ubuntu 20.04 with screen 4.08.00 (GNU) 05-Feb-20

Describe the bug When starting lnav under screen I get following error:

root@dashboard ~ # lnav
Error opening terminal: screen.xterm-256color.

To Reproduce

root@dashboard ~ # lnav
Error opening terminal: screen.xterm-256color.

Reproducible every time.

[tstack]

It seems like the "screen.xterm-256color" terminfo is not installed. Have you tried another value for TERM, like "xterm-256color" ?

Same error and TERM info is available.
