I believe I’d missed an f:

@aelaraji@aelaraji.com You could just remove the {getuser()} part because you added ~.

@falsifian@www.falsifian.org You are correct, but I ended up switching to /data/data/com.termux/files/usr/tmp as suggested by @doesnm@doesnm.p.psf.lt in (#66py4ja). there must have been a reason why that file was placed in /tmp/ in the first place, I just don’t know my way around python that much to figure it out 😅.
