Ubuntu: Build from source using apt-build

Posted by Ish

Ubuntu lets you build/compile a package from source using the apt-build utility. The latter does not ship by default on standard Ubuntu installs. You may install it as follows:

sudo apt-get install apt-build

Now, to compile a package from source, you do the following:

sudo apt-build install package_name

However, since a few days that I’m using apt-build on Ubuntu 14.04 LTS I noticed an error showing up every time I update the software repositories list.

ubuntu-update-error

Upon searching I found that the bug has been around since a while and affects 64bit systems. As few people might be using the apt-build feature therefore it hasn’t been on a priority list. If you’re using apt-build on a 64bit machine it’s highly probable that you’ll encounter the error too.

It can be fixed by specifying the architecture type in the repository configuration file. In this case it’ll be the file /etc/apt/sources.list.d/apt-build.list.

Replace the following line:

deb file:/var/cache/apt-build/repository apt-build main

by

deb [arch=amd64] file:/var/cache/apt-build/repository apt-build main

That should do the trick. You can now run sudo apt-get update without errors showing up.


Update

The bug is being tracked here.

UoM Computer Club – Career & IT Fair 2014

Posted by Ish

The University of Mauritius Computer Club organized a Career & IT fair on 23rd and 24th April 2014. Ibraahim, president of the club, invited LUGM and MSCC. I liaised with other folks within the Linux User Group to present stuffs. Nadim, Pritvi, Ajay and Pawan answered the call for volunteers. On the first day I reached Octave WiehĂ© Auditorium (where the event was happening) around noon. In fact, Nadim called me earlier asking to get a few copies of the LUGM membership form as some students desired to join the force. Well … That was something done already. The day before I printed around 25 copies of the membership form and a couple of LUGM info sheet as well.

As I walked across the auditorium’s corridor I could see several companies busy interacting with students. It’s a career fair after all. I was late, so I rushed till the stand that was allocated to LUGM. Ibraahim sent me a layout two days earlier. I knew where we should be. Jochen, Nadim & Pritvi were already there busy explaining stuffs to the young folks. I took out the printouts and handed them to Nadim. I met Computer Club folks who were seemed very taken up by the event. Yunus, Ratna, Ubeid, Kishan, Saamiyah and several others greeted me. It was lunch time & before I could even start advocating, Yunus came up with food. That was great, I needed to eat. Once I start talking about FOSS I might skip lunch.

The first few students I talked to seemed very much interested with our activities and wanted to be involved as well, by learning & sharing. I was happy to see such a spirit. The membership forms were filled up quickly.

On day two, again I woke up late. Rushed to the bus-stop with two heavy bags carrying my laptops, cooling pad etc. I get in the bus and on the next bus-stop Pritvi gets in. #facepalm The day before I boasted that I’ll reach early next time but I am late again. Anyways, we had some geeky chat till university and he helped me carry the heavy load.

Pawan & Ajay called while we were still on way. They reached before us & started doing some advocacy. Nadim reached a couple of minutes later as we entered the auditorium. Saamiyah popped from somewhere cheering that she finally saw us in the bus. Well, long story cut short, Saamiyah, Pritvi and I we actually travel through same route except we never saw each other along the way (except Pritvi who lives nearby with me). That morning she saw (^^,)

Okies. Time to rock the floor. I fired up my Ubuntu laptop & my mom’s Manjaro notebook. Ahaan, I had to ask mom if I could borrow her laptop for a Synergy demo, she agreed. I was still hopping here & there, when Ratna showed up asking if I could do my presentation earlier. It was initially scheduled for 14h30 but since a slot was free I could do it at 11h30. I was all ok for that. My presentation would cover the aims of Linux User Group of Mauritius and a mini-demo of Synergy.

When it was presentation time, oops, auditorium had more college students than university folks. Now, how do I present a technical stuff to these cute creatures? I fired up my presentation slide, introduced myself and changed the topic completely. There was a mini round of clap with cheering when I did that. I guess they preferred a casual presentation than technical stuffs. So, I took the kids back in time & told them the story of Free Software and Linux. Oh! Not to mention, in the story of Free Software, Microsoft stands as a villain. It seemed like the kids enjoyed the story-telling since it ended with another round of cheering.

In the meantime, outside Ronny brought Linuxfest 2013 certificates. The day before I posted on facebook, calling those who’d be around the university to come and collect their’s. A few showed up.

In the afternoon I asked Ratna if I could have another presentation slot targetted towards university students. She agreed as a slot was free, however, by 14h00 there was practically no one in the auditorium. I took a small group of geeks with me and hopped around the university calling for people who’d be interested with a Linux presentation. Some answered our call positively. Others went un-interested. We even went knocking a classroom & asked the tutor. The gentleman turned out to be another supporter of Free Software and granted his students a short break to attend the presentation. That was how I did my final presentation about the aims of the Linux User Group of Mauritius (^^,)

The event ended on a happy note with a bunch of folks cheering in the cafeteria having tea, coffee & water.
