underfull \hbox (badness 10000) in paragraph
Instead of forcing an underfull box with newline, you could simply leave an empty line to start a new paragraph:
documentclass{article}
usepackage[T2A]{fontenc}
usepackage[utf8]{inputenc}
usepackage{titling}
usepackage{amssymb}
usepackage{amsthm}
usepackage{tikz}
setlength{droptitle}{-3.5cm}
setlength{parindent}{0cm}
newcommand{squad}{hspace{0.5em}}
author{vladgovor77771}
title{Some article}
begin{document}
maketitle
textbf{Task 1}
Task description:
blabla
end{document}
I had a similar issue, I solved it by removing any newline or \ at the and of every sentence that had nothing textual below.
For instance, two examples that causes that problem:
An example. \
This is well used. \
This line will cause the error. \
(I’m a new paragraph) \
Because there’s nothing directly underneath.\
The last line does NOT require a “newline”.
This is a thid paragraph. \
😀
The same is true for figures or similar
This is a line.
Putting a “newline”, as here, before a begin will cause the error. \
begin{figure}[h]
….
end{figure}
