[Bug 1705067] [NEW] system-local terminfo does not search /usr/share/terminfo as README says

[Henrik Holst]

Public bug reported:

    $ lsb_release -rd

    Description:    Ubuntu 16.04.2 LTS
    Release:        16.04

The file /etc/terminfo/README says

    This directory is for system-local terminfo descriptions. By default,
    ncurses will search ${HOME}/.terminfo first, then /etc/terminfo (this
    directory), then /lib/terminfo, and last not least /usr/share/terminfo.

but it seems that /usr/share/terminfo is not used or does not work as
expected?

Repro:

1) Install `stterm`

2) Start `stterm`

3) Type `clear`

Result:

    terminals database is inaccessible

Expected result:

Screen is cleared

Workaround:

Symlink the terminfo database to a user-local ~/.terminfo

    mkdir -p ~/.terminfo/s && ln -sf /usr/share/terminfo/s/stterm*
~/.terminfo/s
