问题:
From the Debian command line, I'm getting a hash sum mismatch after executing aptitude update; aptitude upgrade. Below is the command line output. I've tried an aptitude clean, but this does not seem to help. I've also done a few google searches, but nothing seems to help. I've been getting the mismatch error for a few days.
Any help is appreciated.

Try using apt-get:
apt-get clean rm -rf /var/lib/apt/lists/* apt-get clean apt-get update apt-get upgrade
回答2:
If deleting /var/lib/apt/lists/* does not work...
(esp. if you're behind a proxy), fix "Hash Sum Mismatch" like this:
Create file /etc/apt/apt.conf.d/99fixbadproxy
with this content
Acquire::http::Pipeline-Depth 0; Acquire::http::No-Cache true; Acquire::BrokenProxy true;

Replace your /etc/apt/sources.list with:
deb http://http.debian.net/debian/ jessie main deb http://http.debian.net/debian/ jessie-backports main deb http://security.debian.org/ jessie/updates main
Then I'd also run:
sudo apt-key update -y sudo apt-get update -y sudo apt-get upgrade -y
That should do the trick.

Upgrade apt with sudo apt-get install apt

In my case the following solution didn't work for me:
/var/lib/apt/lists/*- Changing servers to "principal server" (or some other foreing server)
I still was having the same repository giving me the "Hash sum mismatch" error.
I solved trying this solution:
- go to "Software & updates"
- Uncheck all repositories from the "Ubuntu Software" section
- Select the "Autentication" section
- Delete all entries
- Make a
sudo apt update (with no repositories it sould end very soon) - re-open "Software & Updates" -> "Ubuntu Software" and re-check al your needed repositories
- try again with
sudo apt update
Good luck.

sometime reverse proxy(apache,nginx,...) and network will make checksum issue, we can try http proxy of different region to solve the problem:
apt-get update -o Acquire::http::Proxy="$HTTP_PROXY" -o Debug::Acquire::http=true

EDIT: My ubuntu installation has crashed. I am not sure about the exact reason, but this hack is the prime suspect.
I faced a similar issue

Fortunately, the hash mismatch occurred only for one package. Since I was absolutely sure that the package that got downloaded was the intended one, I simply edited out the InRelease file.
The steps I followed: 1. grep for the expected has in /var/lib/apt/lists
sudo grep 46924d3fdb329b18b652bc3410f1f2c92ef1259b9a7d66bb1c5d3804b42a8c1c *
In my case it was
in.archive.ubuntu.com_ubuntu_dists_artful_main_binary-amd64_Packages
Replaced the hash values of expected file with the hash values of received file.
- The upgrade went through.
