Today, while updating my Ubuntu headless server, I got some errors from the mirror I was using: sudo apt-get update Err:1 http://fi.archive.ubuntu.com/ubuntu xenial InRelease Cannot initiate the connection to fi.archive.ubuntu.com:80 connect (101: Network is unreachable)  ...and so on. Seems there is some problem with fi.archive.ubuntu.com, or maybe they stopped serving updates for my old LTS version of Ubuntu. This was solved with some editing of /etc/apt/sources.list sudo nano /etc/apt/sources.list I replaced http://fi.archive.ubuntu.com/ubuntu/ with mirror://mirrors.ubuntu.com/mirrors.txt. If you want to be sure, leave the old lines there commented with #, so you can go back if this doesn't help. So the lines would look like this now: deb mirror://mirrors.ubuntu.com/mirrors.txt xenial main restricted  # deb http://fi.archive.ubuntu.com/ubuntu/ xenial main restricted  deb mirror://mirrors.ubuntu.com/mirrors.txt xenial-updates main restricted # deb ...

I solved a problem with my Lenovo T410 Thinkpad. The machine often crashed when viewing HD video. Black parts appeared on the screen or the whole screen would go black, and the computer would go to a halt. Sometimes Windows 7 gave an error message: "Display driver stopped responding and has recovered". But the system was always in a halt and showing no signs of recovering. This was clearly a problem with the Intel HD Graphics adapter. I updated the graphics driver with Lenovo ThinkVantage Tools, using the Lenovo ThinkVantage System Update. However, the update did not solve the problem for me. After getting frustrated for a while, I found that Intel has a newer version of the driver on their site. You need to use Microsoft Internet Explorer to open this URL: http://www.intel.com/p/en_US/support/detect/graphics The website will aid you in updating your Intel drivers. Unfortunately you need to install some browser add-ins to get it to work, but it pays off in the end. I...

Due to the Kernel of my current Ubuntu Linux being incompatible with the new squashfs, I wanted to update my Ubuntu desktop to the newest version, 11.10. The old version I was using was 10.04 LTS (long-term support). The process had to be done in three parts, and took a quite long time (~3 hours). If you have a slow internet it could take much more. But at least the process was straightforward. First, I upgraded from 10.04 to 10.10 with this guide (quoted below). Upgrade from 10.04 LTS to 10.10 - Network Upgrade for Ubuntu Desktops (Recommended) You can easily upgrade over the network with the following procedure.
