So, this is a quick tutorial, made at the request of the wonderful Allison Sheridan of the NosillaCast podcast, (A technology geek podcast with an eeever so slight Macintosh bias) on how to update apps in Ubuntu 9.10.
Step 1: Open a Terminal.
Step 2: Type “sudo update-manager” without the quotes.
Step 3: Type your password when it asks you.
Step 4a: If a window opens and checks for updates, you’re good. Install the updates.
Step 4b: If no window opens and you get an “update-manager: command not found. Use sudo apt-get install update-manager to install it.” error, install it.
Step 4c: If NEITHER happens, comment on this post and I’ll add more detail. However, this should be enough to get it working.
