Welcome to LQ!!! LQ doesn't provide a way to
delete threads.
No big harm: people sometimes post their solution, and mark Solvd.
You probably found the 'magic' web-search keywords, to find exactly what you wanted.
One thot/suggestion here: since you chose to edit-out the question/post,
but left an enticing title for future searchers, a useful thing you could do is:
Edit #1 again, *click the 'Go Advanced'*, then
change the Title to like deleted.
(It would be better if you chose to instead edit it into a useful Q&A;
then, I'd Edit this into just a "Thanks"

)
Anyway, 'no harm, no foul', and now it's off the visibility of 'ZeroReplyThreads'

See you upon next question!!!

(But
I probably won't have
the answer, since I only know 1% of TheLinuxWorld

)
