Creating an OpenSUSE LXC container on Ubuntu 12.04 May 5th, 2014
I thought it would be good to create an OpenSUSE container on my Ubuntu LXC machine.
I am using the existing OpenSUSE template in /usr/lib/lxc/templates/lxc-opensuse, and some SUSE packages built by Thomas-Karl Pietrowski for Ubuntu from https://launchpad.net/~thopiekar/+archive/zypper, and the build scripts from https://github.com/openSUSE/obs-build
This is how you do it (tested with Ubuntu 12.04):
apt-get install python-software-properties add-apt-repository ppa:thopiekar/zypper apt-get update apt-get install rpm zypper libsolv-tools wget -O obs-build.tar.gz https://github.com/openSUSE/obs-build/archive/master.tar.gz tar xzf obs-build.tar.gz mkdir -p /usr/lib/build mv obs-build-master/* /usr/lib/build # small fixes for the template to avoid some errors sed -i 's/--non-interactive --gpg-auto-import-keys/--gpg-auto-import-keys/g' /usr/lib/lxc/templates/lxc-opensuse sed -i 's#chpasswd#/usr/sbin/chpasswd#g' /usr/lib/lxc/templates/lxc-opensuse |
lxc-create -t opensuse -n demoOpenSuse lxc-start -n demoOpenSuse # login with root and password root |
Things still to be done:
The creation of the image is interactive, since there seems to be unknown keys:
File ‘content’ from repository ‘repo-oss’ is signed with an unknown key ”. Continue? [yes/no] (no): y
File ‘repomd.xml’ from repository ‘update’ is signed with an unknown key ”. Continue? [yes/no] (no): y
/usr/lib/lxc/templates/lxc-opensuse: line 110: patch: command not found
If there are problems with the root password, try this:
echo “root:root2” | chroot /var/lib/lxc/demoOpenSuse/rootfs /usr/sbin/chpasswd
I think the network is not established yet.
But hopefully this is a start…
Install MonoDevelop on OpenSUSE remote workstation December 19th, 2013
My testing environment is a workstation running on a JiffyBox, using X2Go
Here are the steps that I use to setup my machine with OpenSUSE 12.3:
zypper install -t pattern kde4 kde4_basis findutils-locate |
Install X2Go as described here:
zypper addrepo http://download.opensuse.org/repositories/X11:RemoteDesktop:x2go/openSUSE_12.3/X11:RemoteDesktop:x2go.repo zypper refresh zypper install x2goserver |
Then I run these commands so that the login works with a password:
/etc/init.d/x2gocleansessions start sed -i "s/PasswordAuthentication .*/PasswordAuthentication yes/g" /etc/ssh/sshd_config /etc/init.d/sshd start useradd myusername -m passwd myusername |
To install the latest MonoDevelop, follow these instructions:
zypper addrepo http://download.opensuse.org/repositories/home:tpokorra:mono/openSUSE_12.3/home:tpokorra:mono.repo zypper refresh zypper install monodevelop-opt |
Now I had the problem that MonoDevelop did not start.
I tried everything:
. /opt/mono/env.sh cd /opt/monodevelop/lib/monodevelop/bin strace MONO_LOG_LEVEL=debug mono -O=-aot MonoDevelop.exe |
but no error message that I would understand.
Then I tried running monodoc, and this finally gave an error that I could understand:
The program 'browser' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue (integer parameter out of range for operation)'. (Details: serial 131 error_code 2 request_code 25 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) |
This lead me to this bug report: https://bugs.eclipse.org/bugs/show_bug.cgi?id=386955 which mentions X2Go. At the end of that bug, it says that a specific version of Cairo does not support old XRenderers anymore. It has been fixed in version http://www.cairographics.org/news/cairo-1.12.10/
To build and install that version of Cairo, I followed these steps:
wget http://www.cairographics.org/releases/cairo-1.12.16.tar.xz tar xf cairo-1.12.16.tar.xz cd cairo-1.12.16 zypper install gcc libpng-devel libpixman-1-0-devel make libX11-devel libXrender-devel libXext-devel libXt-devel fontconfig-devel ./configure --prefix=/usr --enable-xlib make make install |
Now MonoDevelop and monodoc start fine on OpenSUSE over a remote connection via X2Go.
