Fix failed to fetch Google Chrome packages under Debian

Google decided to drop 32bit support for Chrome lately my Debian Jessie is giving me following errors when doing apt-get update

W: Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release Unable to find expected entry 'main/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)

To fix the issue you need to edit following file: /etc/apt/sources.list.d/google-chrome.list and change the line:

deb http://dl.google.com/linux/chrome/deb/ stable main

to

deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

Save your file and do normal apt-get update.

It seems that the change in google-chrome.list gets overwritten somehow, so I recommend you to set read only permissions on the file with:

chmod 444 /etc/apt/sources.list.d/google-chrome.list

Remember just next time if you need to modify this file to add write permissions back.

Configure LCDd.conf for LC16M VFD LCD 16×2 screen

I wanted to reinstall my old XBMCuntu distro with new version from kodi.tv and I have downloaded latest available iso file from here.

Since my Silverstone LC16M case has 16×2 VFD display it is normal that I want to use it together with all the multimedia keys. In order to get them working kernel module imon must be loaded.

To support LCD in Kodi you will need addon XBMC LCDproc but before installing the plugin you need to have lcdproc package installed and configured. Continue reading “Configure LCDd.conf for LC16M VFD LCD 16×2 screen”

Remove SCSI faulty spare hdd from RAID with mdadm

I manage a lot of servers with simple software RAID1 configuration. One of the disks started to fail notably on partition sdb8, so I had to set all other partitions to failed status before removing and replacing the disk:

mdadm --manage /dev/md0 --fail /dev/sdb5
mdadm --manage /dev/md3 --fail /dev/sdb7
mdadm --manage /dev/md1 --fail /dev/sdb6

After this my /proc/mdstat looked like this:

cat /proc/mdstat
Personalities : [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
