"rpikernelhack" is a fake package name and a directory name used as part of a hack (in the sense of a dirty but expedient solution to a problem) to work around the fact that the Raspberry Pi foundation decided to make /boot a fat32 partition and dpkg does not get on well with fat32. I was the one who initially came up with the idea, though it was refined ...
It's just the directory name given by the developers who have created a Raspberry Pi specific set of patches to the Linux kernel.
It is a fix by the Raspbian developers to fix a FAT file-system corruption issue present in the 2016 kernel, this updates to the 2017 kernel and is nothing to worry about. To make this kernel update you need to use sudo apt ...
Using terminal or your favorite text editor you can define a specific mirror to use in
Just comment out the line
deb http://mirrordirector.raspbian.org/raspbian wheezy main firmware
So it looks like this
#deb http://mirrordirector.raspbian.org/raspbian wheezy main firmware
And replace with a mirror close to you from list ...
That will fix your problem. This is a classic apt issue. The following is taken from the man pages:
upgrade is used to install the newest versions of all packages currently installed on the system from the sources enumerated in /etc/apt/sources.list. Packages currently installed with new versions available are retrieved and ...
It looks like you are having problems resolving the various URLs that apt-get is fetching from.
I would try the following:
1.) Check you have an active Internet connection, try google.com with a second machine for example.
2.) If your Raspberry Pi is attached to your home router, check it has an IP# assigned
3.) Try pinging google.com from the command line:...
I've adapted the instructions here to our case.
First, create the following files in /etc/apt/preferences.d:
Pin: release a=jessie
Pin: release a=stretch
Now, creating a matching set for /etc/apt/sources.list.d:
First, install two packages on your Ubuntu system: qemu-user, and proot.
After you mount the Raspbian SD card, you can do the equivalent of a 'chroot' with:
sudo proot -q qemu-arm -S /mnt/path/to/raspbian/
From there, you can use apt-get commands as though you are actually on the Raspberry Pi. (Use the exit command to exit.)
There are two ways:
Go to the PPA's web page, click on "Technical details about this PPA" and copy paste those lines into your /etc/apt/sources.list or create a new file at e.g. /etc/apt/sources.list.d/pj-assis-ppa.list with these lines as contents. Figuring out which Ubuntu version (for replacing YOUR_UBUNTU_VERSION_HERE) fits best to your Raspbian can be ...
There are pros and cons on both sides of this argument. On the one hand, by keeping your system up to date you insure that you have the latest bug and security fixes; on the other hand, by being on the bleeding edge you may become the victim of an unfound bug or security hole in one of the updated packages, which can prevent your system from working as ...
I think there is a bug in the image. /etc/apt/sources.list contains 2 lines that look like this
deb http://ftp.uk.debian.org/debian/ squeeze main
deb http://ftp.uk.debian.org/debian/ squeeze main non-free
To solve your problem, delete the first one.
Whilst the lines aren't exact duplicate, they do specify duplicate repositories.
if you are sure that subnet set in dhpcd config belongs to already configured interface (I'm guessing, wlan0). Compare IP subnets in /etc/network/interfaces and /etc/dhcp/dhcpd.conf .
Also, on Debian (and thus Raspbian), check /etc/default/isc-dhcp-server, as it should contain name of your interface, like this:
# Defaults for dhcp initscript
# sourced by /...
I actually fixed this error going step by step, apt seems to have a bug in the way it handles ca-certificates-java and openjdk-8-jre-headless on raspbian.
So I did :
sudo apt-get remove openjdk-8-jre-headless openjdk-8-jre
sudo apt-get install ca-certificates-java
sudo apt-get install openjdk-8-jre-headless
sudo apt-get install openjdk-8-jre # Optional, ...
apt-get is part of the Advanced Packaging Tool, the user interface for package management for Debian (and Raspbian, since it is a fork of Debian).
In Debian (and its forks), there is this concept of a "package", a specific piece of software that can be installed and uninstalled. These packages consist of precompiled code, configuration files, and meta-...
It seems Python 3.4 is still in beta, and there is no package prepared for it yet. If youstill want python 3.4, you should download it and build it from source.
You can find it here: https://www.python.org/downloads/release/python-340/ Download the source tar ball. The build instructions should be in there.
These are the steps you can follow.
Grab latest source from this site. (http://php.net/downloads.php) Choose your nearest mirror.
For example, I did "wget http://in1.php.net/distributions/php-5.6.10.tar.bz2"
tar -xvjf php-5.6.10.tar.bz2
make -j4 (if you're compiling it on Rpi 2) else just make
sudo make install
Test it ...
Run apt-get install on the packages kept back. They require something more than a new version of that package (usually a whole other new package as a dependency). That way you'll see what each of them requires. Dist-upgrade will blindly run all of them and possibly remove anything that gets in its way.
I suffered similar issue, and use this way to sovle it. First, comment out this in /etc/apt/sources.list:
#deb http://mirrordirector.raspbian.org/raspbian jessie main contrib non-free
deb http://apt.osmc.tv jessie main
then do sudo apt-get update and sudo apt-get upgrade. Then recover the sources.list
deb http://mirrordirector.raspbian.org/raspbian wheezy ...
For some reason, I couldn't resolve the default mirror's repositories. I added the University of Oxford's mirror (list of all Raspbian mirrors) to my /etc/apt/sources.list.
For the folks who may follow, my sources.list file now looks as follows:
# Original mirror
#deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
# Oxford ...
The jessie-backports contain a precompiled armhf binary of the latest nginx mainline (1.9.10).
### add jessie-backports to sources.list
echo "deb [check-valid-until=no] http://archive.debian.org/debian jessie-backports main" >> /etc/apt/sources.list.d/jessie-backports.list
### optionally add sources, as well ... it's GNU after all :)
echo "deb-src [...
The error you see is because you don't have a www-data user and group, but lighttpd expects to find one. So first, add a www-data user and group:
sudo adduser --system --group www-data
Then you can install lighttpd
sudo apt-get install lighttpd
And that's it. Browse to your Pi's IP address (or localhost on your Pi itself), and you'll be greeted with... ...
Follow the step-by-step guide provided by yours truly :-)
First install XFCE4 (consider also installing the xfce4-goodies package for extra visual candy)
sudo apt-get install xfce4
Then list all installed LXDE-related apps
sudo dpkg --get-selections | grep "^lx"
...and remove them
sudo apt-get remove lxappearance lxde lxde-* lxinput lxmenu-data lxpanel ...
Please note this answer is out-of-date and the current version of Raspbian is jessie, not wheezy. Make sure of which one you are using before you do anything.
Your raspbi could not find a valid mirror so you need to find a working mirror.
For valid and working mirrors please check http://www.raspbian.org/RaspbianRepository
After getting valid mirror ...
Try sudo apt-get --purge remove apache2 and then sudo apt-get autoremove. I had that same thing with emacs due to it installing other dependencies. emacs would still be there after --purge remove. Autoremove helped removing the dependencies which were installed with emacs.
Looks like it's trying to use IPv6. I bet your connection doesn't have IPv6 (yet).
Make a config file that disables IPv6.
Run the command sudoedit /etc/apt/apt.conf.d/99force-ipv4, put Acquire::ForceIPv4 "true"; in it then save it.
If you want a temporary solution, run apt-get -o Acquire::ForceIPv4=true update instead of just apt-get update to make it use ...
You need to make a distinction between Raspbian (nothing to do with the Raspberry Pi Foundation) and the image based on Raspbian which may be downloaded from the Raspberry Pi Foundation site (raspberrypi.org).
Raspbian is based on Debian and as far as I am aware only includes Debian packages.
The Raspberry Pi Foundation image is based on Raspbian but also ...
