I am running the demo MoveIt Servoing,I am using the following commands
1. roslaunch ur_gazebo ur5.launch
2. roslaunch ur5_moveit_config ur5_moveit_planning_execution.launch sim:=true
3. roslaunch ur5_moveit_config moveit_rviz.launch config:=true
After running the following command
4. roslaunch moveit_servo spacenav_cpp.launch
I am getting the following error Could not open the space navigator device. Did you remember to run spacenavd (as root)? I tried resolving the issue using the [website Link Solution], however I am getting the following error
root#abc-ThinkPad-P17-Gen-2i:/home/abc/ws_moveit# rosrun spacenav spacenavd

I'm using yocto 2.6 (thud) to customize my linux image and now I can use bitbake to generate an image with my own applications, the image runs well on the board.
Now I'm trying to populate the sdk and I do:
bitbake dey-image -c populate_sdk
then I have lots of warnings, like
The following packages have unmet dependencies:
apt-dev : Depends: apt (= 1.2.24-r0.1) but it is not going to be installed
Recommends: bash-dev
Recommends: libcurl-dev but it is not installable
hwmoniter-dev : Depends: hwmoniter (= git-r0.7) but it is not going to be installed
Recommends: libmosquitto1-dev but it is not installable
E: Unable to correct problems, you have held broken packages.
Summary: There was 1 WARNING message shown.
It seems that populate_sdk finally succeeded with warnings, the sdk (*.sh) is generate and it can be installed, but I can't find many header files I assumed to be there.
So what do the warnings mean? What's the difference between "not going to be installed" and "not installable"? How can I fix those warnings?
Thanks
First of all, below is required information.
OS: macOS Mojave 10.14.2
Node: 10.13.0
AndroidStudio: 3.1.4
When I run appium doctor, I'am getting two optional dependencies are missing.
1. `opencv4nodejs`
2. `bundletool.jar`
If I try to install opencv4nodejs, but I got warning:
opencv4nodejs#4.14.0 has no binaries
(It seems like auto build failed)
And I have no idea how to add export bundletool.jar as PATH.
I just ran into this myself. Installing opencv4nodejs was pretty easy - for that, I used:
npm -g install opencv4nodejs
There may have been dependencies of 'opencv4nodejs' that I had to install - I can't remember; that may have required me to install 'make' with brew install make
The hard one was the bundletool.jar - here are the steps I followed for that:
Searched for 'bundletool.jar' and found a place to download it from Google - I got 'bundletool-all-0.8.0.jar' from https://github.com/google/bundletool/releases
I renamed this file to just 'bundletool.jar' and placed in my Android SDK folder, under its own sub-folder called 'bundle-tool' - full path: /Users/{USER}/Library/Developer/Android/sdk/bundle-tool
I had to make the bundletool.jar executable with:
chmod +x bundletool.jar
Added the 'bundle-tool' folder to Path with the following addition in my ~/.bashrc file:
PATH="$PATH:$ANDROID_HOME/bundle-tool"
Now running which 'bundletool.jar' is happy and finds it in the 'bundle-tool' folder I created (see step 2)
Running 'appium-doctor' is now satisfied - and doesn't report any missing dependencies.
Hope that helps.
2019-10-31 update:
With MacOS Catalina (specifically 10.15.1) - I ran into a problem with installing opencv4nodejs using the npm command shown above. Opencv4nodejs wants to be built - but using C++ 11 features (from what I read) and has a problem with constexpr on MacOS. So, I first installed OpenCV with Brew - using brew install opencv#4 and then had to set the environment variable to not autobuild OpenCV with export OPENCV4NODEJS_DISABLE_AUTOBUILD=1
Then I was able to install opencv4nodejs with the npm command shown above - and appium-doctor shows that its dependencies are in place.

I don't know what is causing your errors, but you could try ASDF with the Elixir plugin. This allows you to install multiple versions of Elixir and its dependencies, and uses your user environment with shims instead of installing to system directories. This avoids many of the dependency and permission problems that comes with performing a single system-level installation.
It looks like you have both emacs23 and emacs24 installed. The failure is happening when trying to build for emacs23. Unless you really want emacs23 for some reason, remove it and then it should install fine:
sudo apt-get remove emacs23
It is possible you might have to delete some of the other emacs23-* packages by hand.
This problem only affects the erlang-mode package, which adds support for editing Erlang code in Emacs. If you're not using Emacs (or not developing Erlang in it), you can just uninstall that package:
sudo apt remove erlang-mode
As noted in Penguin Brian's answer, this happens when installing erlang-mode on a system using Emacs 23, as erlang-mode only supports Emacs 24 or newer. (Looks like this is a bug in the package: it shouldn't try to compile itself for unsupported Emacs versions.) If you do want to use erlang-mode in Emacs, I'd suggest running Emacs 24 and installing the Erlang mode from MELPA.
I am trying to install opencv using conda on a windows machine. I am running the following command:

Other people seem to have similar problems (https://github.com/conda/conda/issues/4393). One of the solutions I found was to downgrade conda. I am currently using conda 4.5.4 and when I try to downgrade using conda install conda=4.2 I get the following error:

Regarding this issue I found the following similar posts:
conda update conda permission error
Anaconda : Update conda failed because permission error
But the solutions given do not fix my problem.
I also had a problem with installation and usage of the OpenCV library. If you have such а problem, you can try:
uninstall opencv with: conda remove --yes opencv (in case you have an installation but it does not work properly)
install OpenCV through pip: pip install opencv-python
I think this is a problem with opencv that comes from Anaconda channels. I came across this problem four months ago. Тhe problem may be resolved right now.
My guess is that you did not run this command with administrator privileges！
Trying to use the perf profiler. I've installed linux generic tools, but no luck. Here is the message I'm getting:
r#r-K55A:~$ perf
WARNING: perf not found for kernel 3.16.0-45
You may need to install the following packages for this specific kernel:
linux-tools-3.16.0-45-generic
linux-cloud-tools-3.16.0-45-generic
You may also want to install one of the following packages to keep up to date:
linux-tools-generic
linux-cloud-tools-generic
I've tried to install the above packages, but I get the following error:
Unable to locate package linux-tools-3.16.0-45-generic
E: Couldn't find any package by regex 'linux-tools-3.16.0-45-generic'
You can safely use this snippet:
sudo apt install linux-tools-common linux-tools-generic linux-tools-$(uname -r)
I could never get it working. Updated my Kernal to newest stable version and tried to download the above packages from sudo apt-get install. I finally found the packages manually online, and it's working fine.
