Well, yes ... and no. You do not need to check the integrity of EVERYTHING
you download, as long as you stay INSIDE the distro's repo. Wow, Latin
. More explanation. Linux comes in several flavors, wel call it a "distro". Every distro has a library of software for it, without that, Linux would still be very usable, but...you'd have to write all the software. Like re-inventing sliced bread...it's not very productive.
I noticed you use Mint, well, Mint has quite a bundle of software, for the everyday user, but a more selective user could time and again need/want/require software that's not in the repo, hence, download-n-check. The process is simple, let's take an example with a download, go to the download page for DSL
, and look. All the way down, there is a file called dsl-4.4.10.iso
, okay, right under that is an other file, open it
and look, that's an MD5 checksum, let's use that.
Once the iso is downloaded , enter a console, navigate to the folder where the iso is located and issue:
this is what you should
...now, compate this with the line of thext found on the download site.
If the two are identical
, the downloads is clean...and safe to use.
Granted, DSL is somewat dated, but..it illustrated the concept. Try it! Download Crunchbang
for example, they have a checksum too...did you notice?
Hope this helps!
