OpenNI – error CS0006: cannot find metadata file `System.Windows.Forms.dll’

Alex — Thu, 01 Dec 2011 13:41:37 +0000

During installing the OpenNi kinect drivers, found here: https://github.com/OpenNI/OpenNI, I came across this error:

make[1]: Entering directory `/home/alex/kinect/OpenNI/Platform/Linux-x86/Build/Samples/SimpleViewer.net’
gmcs -out:../../../Bin/Release/SimpleViewer.net.exe -target:winexe -unsafe -o+ -r:OpenNI.net.dll -r:System.Windows.Forms.dll -r:System.Drawing.dll -lib:../../../Bin/Release ../../../../../Samples/SimpleViewer.net/*.cs ../../Res/AssemblyInfo-OpenNI.cs

make[1]: Leaving directory `/home/alex/kinect/OpenNI/Platform/Linux-x86/Build/Samples/SimpleViewer.net’

To fix it, simply install the following package:

sudo apt-get install mono-complete

Once finished, re-make and make install and everything should be dandy!

Java – .jar Error 127 /bin/sh: javac: not found.

Alex — Thu, 01 Dec 2011 13:33:42 +0000

If you’re getting a similar error to this while trying to compile java files (.jar) then you’re probably missing the jdk, in ubuntu it’s called “sun-java6-jdk” so just go ahead and install that and all should be good!

make[1]: Entering directory `/home/alex/kinect/OpenNI/Platform/Linux-x86/Build/Wrappers/OpenNI.java’
javac -d Release ../../../../../Wrappers/OpenNI.java/src/org/OpenNI/*.java
/bin/sh: javac: not found

make[1]: Leaving directory `/home/alex/kinect/OpenNI/Platform/Linux-x86/Build/Wrappers/OpenNI.java’

FIX:

sudo apt-get install sun-java6-jdk

Steam in Wine, Repeated Windows

Alex — Fri, 01 Jul 2011 23:08:29 +0000

After installing Steam on my linux machine in wine I noticed a really annoy bug, the windows of steam are tiled across my screen as shown in the screenshot below.

Fix:

I managed to fix this by opening up the ‘Configure Wine’ program that comes with wine and under the Applications tab switching from Windows XP mode to Windows 7, this fixed this bug and I now also have system borders on the steam windows.

Installing Wine:

If you’re interested in getting steam installed I used this guide - https://wiki.ubuntu.com/UbuntuMagazine/HowTo/InstallingSteam – It’s pretty simple and only takes a few minutes to do. Below is a quick, simple breakdown of what that guide says to do.

Download wine:

sudo apt-get install wine

Download the steam installer from here:

http://www.steampowered.com/v/index.php

Copy over the tahoma.ttf font from a Windows install (or Download it here – http://source.winehq.org/source/fonts/tahoma.ttf ). Do this command from the folder you downloaded the font to.

cp tahoma.ttf ~/.wine/drive_c/windows/fonts/

(If it doesn’t work and says the folder is missing or somthing like that do the following and then re-do the cp)

mkdir ~/.wine/drive_c/windows/fonts/

Finally install Steam (Do this command in the directory you downloaded the Steam installer to):

msiexec /i SteamInstall.msi

GNOME 3 – Delete Key Not Deleting/Working in Nautilus

Alex — Sat, 11 Jun 2011 19:17:59 +0000

In GNOME 3 it seems that the keyboard shortcut to delete a file in Nautilus is actually Ctrl+Delete, this is fine I guess if it’s trying to stop people accidentally deleting files or something but it’s pretty annoying.

To change the keyboard shortcut from Ctrl+Delete back to the usual Delete do the following:

Open a terminal and type:

dconf-editor

If you don’t have it, install it the usual way.

In the application that just opened, on the sidebar click:

org > gnome > desktop > interface

And check the box entitled: can-change-accels.

Now, leave this window open and open up Nautilus.

Select a file that you want deleting and then click on Edit in the Nautilus menu, hover over the Move To Trash button and here press the button you wish to assign to the action, so for example Delete. You may have to press it twice (the first time it will remove the old key-binding and the second will assign it the new one.)

Go back to dconf-editor and uncheck the can-change-accels option to stop any other keyboard shortcuts being changed and you’re all done!

How To Fix: Error: Cannot retrieve repository metadata (repomd.xml) for repository: Dropbox. Please verify its path and try again

Alex — Tue, 24 May 2011 16:56:04 +0000

After installing dropbox from the RPM package availble on the site on a new Fedora 15 install, I was unable to use yum without coming across this error:

$ update
Loaded plugins: langpacks, presto, refresh-packagekit
http://linux.dropbox.com/fedora/15/repodata/repomd.xml: [Errno 14] HTTP Error 404 – Not Found : http://linux.dropbox.com/fedora/15/repodata/repomd.xml
Trying other mirror.
http://linux.dropbox.com/fedora/15/repodata/repomd.xml: [Errno 14] HTTP Error 404 – Not Found : http://linux.dropbox.com/fedora/15/repodata/repomd.xml
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: Dropbox. Please verify its path and try again

For some unknown reason dropbox repos dont seem to work past 13 so you’ll need to change the dropbox.repo file from detecting the current release to 13 like so:

Open the dropbox.repo file:

sudo gedit /etc/yum.repos.d/dropbox.repo

Change the baseurl from $relesever to 13 like so:

Original:

[Dropbox]
name=Dropbox Repository
baseurl=http://linux.dropbox.com/fedora/$releasever/
gpgkey=http://linux.dropbox.com/fedora/rpm-public-key.asc

New:

[Dropbox]
name=Dropbox Repository
baseurl=http://linux.dropbox.com/fedora/13/
gpgkey=http://linux.dropbox.com/fedora/rpm-public-key.asc

Save and close and everything should be working, try using sudo yum update to check and the error should have gone away. If not give a reboot a try.

OpenShot, libmp3lame and Ubuntu

Alex — Thu, 28 Apr 2011 22:36:18 +0000

If you’re getting the following error while trying export a video under several different codecs in OpenShot including AVI, MOV and MPEG using (mpeg2, mpeg4 or h.264) chances are this might help you with that error.

The following formats/codecs are missing from your system:

libmp3lame

You will not be able to use the selected export profile. You will need to install the missing formats/codecs or choose a different export profile.

This is a simple fix:

Open up Synaptic Package Manager
Search “libavformat”,

If the current package installed is “libavformat52″ select “libavformat-extra-52″ (alternativly “libavformat-unstripped-52″ should also work).
Else the package might be “libavformat53″ so simply change to “libavformat-extra-53″, basically it might end in different numbers, it should work the same.

Hit Apply and approve the changes.

Error: “end_request: I/O error, dev sr0, sector xxxxx” – Linux

Alex — Sun, 20 Mar 2011 14:46:49 +0000

Error:

end_request: I/O error, dev sr0, sector 537392

If you’re getting a similar error filling your screen once you’ve installed Ubuntu, don’t panic. It’s pretty common which is basically because Ubuntu (or any other Linux distro) can’t control your CD/DVD drive properly, it’s probably trying to open/close it but doesn’t know if it has or not. The problem is that you don’t get to see what Ubuntu wrote before because it’s filled your screen up with this error.

If you’ve just installed Ubuntu this probably happened when it wanted you to take the disc out and close the cd tray (if there is one) then hit Enter to finish the installation, so just do that and ignore this error.

Failed to build Planner-0.14.4 in Arch Linux

Alex — Mon, 14 Mar 2011 10:35:43 +0000

When trying to install Gnome Planner ( http://live.gnome.org/Planner ) in Arch Linux, I came across this error:

Error:

/usr/bin/pygobject-codegen-2.0: line 11: /usr/bin/python2: No such file or directory
make[2]: *** [planner.c] Error 127
make[2]: Leaving directory `/home/alex/Desktop/planner-0.14.4/python‘
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/alex/Desktop/planner-0.14.4′
make: *** [all] Error 2

To fix this, I made a symbolic link from /usr/bin/python2.7 to /usr/bin/python2, this should work with other similar errors involving missing python2 file.

sudo ln -s /usr/bin/python2.7 /usr/bin/python2

Once you have made the made the symbolic link continue to make and install the program as usual.
