Avoid use of wget without progress bar. Use
wget --progress=dot:giga <url>. Or consider using -q or -nv (shorthands for --quiet or --no-verbose).22

Description
wget without the --progress flag will result in excessively bloated build logs when downloading larger files.
That's because it outputs a line for each fraction of a percentage point while downloading a big file.
