termdown snap package is broken

[Vaisakhkm2625]

Hi

First of all, thanks for making this wonderful yet simple app... i almost use it every day

i noticed that termdown installed from snap store is not working properly...
https://snapcraft.io/termdown

it is showing:

❯ snap run termdown
Traceback (most recent call last):

    sys.exit(main())

    setupterm(term=_os.environ.get("TERM", "unknown"),
_curses.error: setupterm: could not find terminal

it was weird because simple python curses script i wrote is working in terminal....

so I googled for error and found
https://stackoverflow.com/questions/9485699/setupterm-could-not-find-terminal-in-python-program-using-curses

so i did

export TERM=linux
export TERMINFO=/etc/terminfo

then it started working...

so this is might be issue with sandboxed nature of snap,
i am hoping you could do some work around like hard coding these variables... or fix packaging
please consider closing this issue if i am wrong

Thanks.

(btw, i am using it from pypi)
