None of these were any real problems, but easier to spot real issues if pylint
is a bit quieter. Apart from the pylint overrides being sprinkled over the code
base, this commit also fixes occurences of the following issues:
- logging-not-lazy
- logging-format-interpolation
- unused-import
- unused-variable
The progress bar wasn't updated after the downloaded completed,
so the final progress bar would look something like this:
[99/100][===============================.] ETA: 0:00:00
This can be interpreted as the file didn't download completely.
