Broken Docker in Debian Jessie

Tue, 01 Sep 2015 21:19:41 +0000

So after a few dist-upgrades, docker is not running anymore in my debian Jessie. A quick run of sudo service docker status shows me:

● docker.service - Docker Application Container Engine

Ops, problem with aufs. A quick fix would be to delete it. You might lose some data, so please do it with care.

KDE is fully broken in Debian Jessie/Testing

Fri, 31 Jul 2015 20:05:09 +0000

I use Debian Jessie, and I am the type who do this command frequently:

sudo apt-get update && sudo apt-get dist-upgrade

Now I am suffering from the consequences. The desktop is completely broken. I googled around, and there was nothing. So I thought something in my laptop is broken at first.

Well, if you are a long enough linux user, this kind of stuff is kind of normal. It always happens once in a blue moon. It happened once when I was upgrading Fedora. It happened once when Debian removed ati driver. This stuff is normal, it’s also Debian Testing anyway. One just need to keep calm and fix the problem.

AWS Eb CLI (v3): How to fix ssl_wrap_socket error in Debian Jessie

Mon, 26 Jan 2015 20:11:28 +0000

This is the first time I’m deploying stuff to elasticbeanstalk, and when I’m trying to deploy my private project, I realized the eb cli I download is the version 2 and has different syntax. I installed the version 3, and it seems like it can only be installed using python package manager pip. After installing it, this is what I get:

rowanto@Rowanto-Deb ~ $ eb
Traceback (most recent call last):

And I’m like, what? Googling around the last line returns you many result, but not those relevant with the eb cli v3. There’s also a post which suggest that we use the bundle version (it’s a zip file) of aws cli, but I can’t find a bundle version of eb cli. Long story short, I found this post which helped me to fix the problem. Thanks to @guss77!

How to fix libgdbm3 update problem in Debian

Thu, 13 Nov 2014 19:22:33 +0000

In case you recently tried to update your debian system, and got an error related to libgdbm3 like this:

Preparing to unpack .../libgdbm3_1.8.3-13+b1_i386.deb ...
Unpacking libgdbm3:i386 (1.8.3-13+b1) over (1.8.3-13) ...
dpkg: error processing archive /var/cache/apt/archives/libgdbm3_1.8.3-13+b1_i386.deb (--unpack):
trying to overwrite shared '/usr/share/doc/libgdbm3/changelog.Debian.gz', which is different from other instances of package libgdbm3:i386
Errors were encountered while processing:
/var/cache/apt/archives/libgdbm3_1.8.3-13+b1_i386.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

You can fix this easily by deleting the libdgbm3 changelog file.

CVE-2014-6271: what is it and how to check if you're vulnerable and fix it

Thu, 25 Sep 2014 09:00:00 +0000

What is actually CVE-2014-6271?

Actually redhat did a very good job describing it: https://access.redhat.com/articles/1200223 From what I’ve understood, it’s basically a bug that allows you in bash to do some other command after the function declaration in a variable.

Let’s change the example a little bit, so that it’s more easier to read:

 env your_function='() { echo "your function do something";}; echo "but I can still add other command after your function"' bash -c "echo this is a test"

If you system is affected with the bug, if you run that command, you will see the text “but I can still add other command after your function”.

Monitor resolution not properly detected in Linux (Debian 7 or Wheezy)

Fri, 09 Aug 2013 09:00:00 +0000

So I have an ATI HD5xxx graphic card in my desktop personal computer. It’s a nice and quite fast card. It also has three display adapters: HDMI, DVI, DisplayPort. On my desk, there are two monitors. One of them have a DVI and a VGA adapter. The other however, only have VGA adapter. Do you see the problem here?

My graphic card has no VGA adapter, because of this, I need to use some adapter, and because I used an adapter, the resolution of the monitor is not detected properly. The native resolution of that monitor is 1920x1080 pixels, but I can only set it to 1440x900 when I use the adapter (which looks quite ugly). This problem is easily solveable in Windows 8. The windows’ ATI Cataylst has an option to force a resolution on the monitor. So I can just force 1920x1080 and it works perfectly. Debian (or other distribution like Fedora) however, does not have this option..

Installing Skype on 64-bit Debian 7 (codename: Wheezy)

Thu, 08 Aug 2013 09:00:00 +0000

So it was when I was trying to install Skype on my brand new Debian 7 (Wheezy) when I encountered this problem:

package architecture (i386) does not match system (amd64)

Actually I was a little shocked. I just downloaded the Skype package for Debian from the official website then tried to install it normally using “dpkg -i ”, and it used to always work (normally). Actually I came from the rpm world (Fedora and CentOS) and have been only using Windows 8 for the past few months for my thesis, so I am actually wondering whether I’m the one who is a little out of date, or this is just a deb thingie, or I’m just too thick and dumb. But really, I never encountered this kind of problem. This is a first for me.
