For Linux Mint 17, do:

  1. Launch Menu->Administration->”Software Sources”.
  2. Tick the option “Unstable Packages (Romeo)”.
  3. Carefully read the warning in the dialog that pops up and click “Yes” if appropriate.
  4. Launch the Update Manager and click on “Refresh”.

How to Connect to Cisco AnyConnect VPN in Ubuntu

Last updated: November 1, 2014

Many businesses and universities use Cisco AnyConnect as their VPN solution. Although there is a native Linux client offered by Cisco, it is not very well supported, and in some cases the user does not have access to the client. Fortunately, there is a simple solution to this problem – thanks to OpenConnect.

OpenConnect is a client for Cisco’s AnyConnect VPN. It is free software, and is released under the GNU LGPL v2.1 . Getting connected to an AnyConnect VPN is easy with OpenConnect and the TUN/TAP kernel module that is built into the Linux kernel.

1. First run command below to active th TUN module:

sudo /sbin/modprobe tun

2. Install OpenConnect:

sudo apt-get install openconnect

3. Connect to VPN, run:

sudo openconnect yourvpn.example.com

It prompts you to type in username and password. Once these are authenticated, the VPN connection is established.

Keep the terminal window open while the VPN session is active. Network resources such as shared folders, NAS drives, servers, and workstations should now be available. To close the VPN session, press Ctrl+Z in the terminal window. Abruptly killing the terminal window without properly closing out of the VPN session can lead to issues when attempting to reconnect in the future. These issues can typically be resolved by restarting the machine.

For OpenConnect manual, run command man openconnect.

Blender is a professional free and open-source 3D computer graphics software product used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games.

So far the latest stable release is Blender 2.72b, which was released a week ago. See the new features in its website.

1. Click the link below to bring up Ubuntu Software Center and click the install button to install the package libsdl1.2debian:

2. Download Blender for GNU/Linux from the official link below. You may first check your OS type, 32-bit or 64-bit, by clicking on “About This computer” from shutdown menu (top-right corner gear button).

www.blender.org/download/

3. – a). For single use – If you have only one user on the Ubuntu system, just extract the package to user Downloads folder and run the executable from the result folder:

3. – b). To make all users to be able to run the blender release, extract the package to /opt/ directory.

To do so, press Ctrl+Alt+T to open terminal, run command below to open your Downloads folder as root/administrator:

Install gksu from Ubuntu Software Center if need. Type in your user password when it asks.

When the folder opens, do:

  1. Right click on Blender package and select open with Archive Manager.
  2. When Archive Manager opens, select Extract to computer -> /opt/

When done, you should see the blender folder under /opt/. For shot, I’ve rename it from “blender-2.72b-linux-glibc211-x86_64” to “blender”.

4. Create a launcher for Blender so that we can start it from the Unity Dash or App Menu.

Press Ctrl+Alt+T to open terminal. When it opens, run command to create .desktop file and edit it with Gedit text editor:

gksudo gedit /usr/share/applications/blender-2.7.desktop

When the file opens, paste below into it and save.
