Excessive downvoting on what appears to be a legitimate question by new users is a bad thing. It's unreasonable to expect a new user to understand why a question that had depth and subtlety was repeatedly downvoted. It would be more appropriate if whoever disapproved of the line of reasoning taken by the author of the question stopped at the first downvote. No one asked for more information from the OP, perhaps because none was needed, the OP was left out of the loop, and was left defenseless to eat his four downvotes until I intervened in Meta and the question got four upvotes after that.
Four downvotes is lot of downvotes for a good question to get, even though now it is reduced to three downvotes, so it should be interesting to read what follows about why I think the original question was a good one. To be fair the original question now has four upvotes and three downvotes, which shows that the issue under discussion has at least two sides. Two sides, not one side.
I'm not sure that it was the intent of the author of the question to post a good question, but that is what he did, even though it was badly written initially. I upvoted the question and here is the explanation for why I upvoted it.
The author wanted to install two Kali linux tools in Ubuntu. There are two alternatives that are available.
Automatic - Install the tatoolin script in Ubuntu and install the two packages he wants from the Katoolin interface.
Manual - Search for the two packages, install required dependencies for the packages if necessary and install the packages.
Method 1 can be hazardous to the stability of the operating system, so it may be overkill to install Katoolin for the purpose of installing only two packages. However the author of the question may be installing more than just two Kali linux tools, so he should be offered that alternative.
Method 2 can be too difficult for some users, especially if package If you dependencies have to be manually installed too. However the author of the question may have experience in compiling and resolving package dependency issues, so he should be offered that alternative too.
What a person who is trying to force close this question by multiply downvoting it would say without thinking is that this proves that the question is unclear because we should compel the author to state precisely his level of expertise as a user and his future intentions regarding installing other Kali linux tool in Ubuntu. In fact the contrary works just as well for the purpose of all users of Ask Ubuntu who want know about how to install only one or two Kali linux tools without destroying their operating systems.
