I'm trying to get onto the xfce4 client from my chromebook (and it has worked before), however now this error is popping up. How do I fix this error?
My guess is you may not have the right user privileges. According to the error message you provided you are running an Ubuntu Linux environment.
If you haven't tried running the program through the terminal yet, attempt to do so.
The terminal can typically be opened by the key combination Ctrl+Alt+T on ubuntu linux.
Try using sudo command before running the program. This will run the command you enter using root privileges.
For example, if running the program on your terminal is
myName#ubuntu: xfce4
And this encounters an error, try to use sudo beforehand like so:
myName#ubuntu: sudo xfce4
Alternatively you can log in and not have to type sudo before every command.
myName#ubuntu: sudo bash
password:
If this fails you may need to update the package that contains the library. This can be done on the terminal in a fashion similar to:
myName#ubuntu: sudo apt-get install --only-upgrade xfce4

Question:
When I launch Minecraft pi it shows a black window for a second and closes.
in command line it gives me the error:
failed to add service - already in use?
after command:
sudo minecraft-pi
Try this:
sudo apt-get purge minecraft-pi
sudo apt-get update
sudo apt-get install minecraft-pi
If all else fails why not just play the full version of Minecraft? (Minecraft Java Edition). https://forums.raspberrypi.com/viewtopic.php?t=279135
I've recently installed the balena-cli package via npm (which itself has been installed using nvm) which works fine when accessed from my default user.
However whenever I try to access npm, nvm or balena-cli using sudo they all print the following error
$ sudo npm
sudo: npm: command not found
$ sudo nvm
sudo: nvm: command not found
$ sudo balena
sudo: balena: command not found
I tried using sudo chown on all 3 but to now avail.
Basically, none of the Node related functions can be accessed using root.
Any suggestions on how to resolve this, perhaps by the use of environment variables?
As a stop gap, I found out that running the same command after switching to root works fine with the following command;
$ sudo -s
However, since it's a stop gap, it would be great to find a way to run the same commands without switching back and forth between root.
Basically once do check that have you flashed Balena image correctly and then check the network permissions and login to Balena with root and run commands with su instead of sudo then your issue might clear.
I'm installing new service in ambari managed cluster. my connection to hortonwork's repo seems too bad, it took lots of time to install ambari-server and ambari-agent it self (onece i almost thought it was dead).
the problem is that when i'm installing new service (e.g zeppelin, it also requires install other dependencies), the progress bar get stuck at 26% percent. it confused me if the installation get stucked or it's just too slow.
the command
ps -ef|grep apt
shows the the install is still there. only can't track the progress via /var/log/apt/term.log like normal apt-get installation (it shows the download progress).
the command shows the apt-get comes with an "-q" options which prevent me from tracking the log file.
so my question is that is there any place i can change the default behavior?
The -q option is added to "apt-get" command based on log level of ambari-agent. I.e. if log level for ambari-agent is set to DEBUG then apt-get without -q option is executed.
You can edit /etc/ambari-agent/conf/logging.conf, in [logger_root] section comment default line level=WARNING and add level=DEBUG. Then retstart ambari-agent. Now if you install any service them apt-get without -q will be executed.
Note:
If /etc/ambari-agent/conf/logging.conf does not exist then copy it from /etc/ambari-agent/conf/logging.conf.sample
Ambari agent specific changed need to be done on all cluster node
I was prompted to update Erlang on my machine and I did. Then when I restarted my server I was prompted to update using mix local.hex.
When i did this it gave me the following error.
mix local.hex --force didn't work either.
I eventually found out that I installed erlang originally without brew originally which is where the prompt came from. After I updated it, it caused an issue with mix local.hex.
I manually removed the folder /usr/local/lib/erlang and all erlang on my machine. I installed erlang using 'brew install erlang' and then ran 'brew link erlang'
This originally didn't work because I didn't have permission but then I ran the following to get permission.
sudo chown -R $(whoami) /usr/local/lib
After that 'brew link erlang' worked and I was able to run 'mix local.hex' like normal.
So I am facing a very strange peculiarity. I am trying to run dpkg on a remote server via SSH. My code works perfectly if I click Run through Xcode, but if I click Build > Archive then Export as a Mac Application, all SSH commands sent to the server work, other than "dpkg". Any ideas why this might happen?
Apparently, after many days of facing that issue, I tried installing via dpkg a Deb that was already located on my server and it worked. What's even more strange is that while scp would transfer the file, dpkg would just not use it! What made the trick was getting the file via curl and then running dpkg normally. No idea why that's the case though, as both Deb files had the same owner, group and permissions. And both were running by root, so it wasn't a permission error.
