Recently I tried to use bluetooth on arch linux. I'm using WM so after installing packages such as:bluez and bluez-utils I ran a command bluetoothctl. Then I tried to run power on but I got an error Failed to set power on: org.bluez.Error.Blocked. I searched on the internet but I only found Failed to set power on: org.bluez.Error.Failed solutions, so it's not what I want.
try:
rfkill block bluetooth
rfkill unblock bluetooth
and then open bluetoothctl again.
If it does't work I would try:
systemctl stop bluetooth.service
systemctl start bluetooth.service
In my case the driver was stuck somewhere (Linux 5.16.10 x86_64), the solution was:
# rmmod btusb
# modprobe btusb
# systemctl restart bluetooth
I'm trying to use rabbitmq for a django tutorial but when I want to start the server I get this error:

I've searched for port to see that if it's in use or not and I used lsof -i :25672 and I get nothing.
I don't know too much about these things so if you need anything please tell me.
Try:
sudo lsof -i :25672
sudo kill <PID>
sudo rabbitmq-server
Where <PID> is the process ID that is occupying port 25672
I have encountered this issue. I figured out that this issue is coming because the rabbitmq-server is already running on the machine.
I have used the following command
rabbitmqctl.bat status to know the status of the rabbitmq-server. This helped me to know if the server is up or down.
If it is up, this could the reason you are getting the error that you have specified in your post.
You can issue the following command to make the server down
rabbitmqctl.bat stop
Now you can try starting the rabbitmq-server by issuing the following command
rabbitmq-server start
Note that I am using Windows. And I have executed these commands by pointing the command prompt to C:\Program Files\RabbitMQ\rabbitmq_server-3.8.14\sbin as my rabbitmq installation directory is C:\Program Files\RabbitMQ\rabbitmq_server-3.8.14.
I have encountered this before. Here is what caused it and how I fixed it:
This is one of those commands which requires the magic word sudo (i.e it needs a superuser privilege).
If you forget to add sudo to the command, it begins the process but later fails when it hits a superuser-only roadblock. This leaves you with an incomplete process. Now when you decide to add sudo, it attempts the same process again but finds out that someone without the right privilege has made a mess or is still messing around.
Then the solution will be to cancel out whatever the first command has started and try again.
sudo lsof -i :25672
This list out details about the port 25672
You will see the PID (process ID) e.g 1301
Then stop the process on that port with:
sudo kill <PID>
for example, sudo kill 1301
And make sure you are killing the right process if not you may get into trouble.
Now, retry the command with sudo:
sudo rabbitmq-server
ALSO,
In most cases, this error occurs because without deliberately stopping the rabbitmq-server, it always keeps running even after you restart you system.
another way to stop rabitmq server windows+R then type "services.msc" and then find for RabitMq.slelect and stop from left top corner.
Then re run your rabitmq server.
-Hi guys, I am putting up an answer that can help Googlers to run multiple rabbitmq-server on the same machine. Trying to achieve the latter, I ran into a similar error reported in the first place and solved that by defining:
export RABBITMQ_DIST_PORT=anything_other_than_25672
as stated in the documentation:
https://www.rabbitmq.com/networking.html#epmd-inet-dist-port-range
if you are using windows go to task manager and stop rabbitmq from running...
then reload the rabbitmq-server
For Linux others answered but in Windows you should press Ctrl+Alt+delete and select task management and in that end proccess that depends on erlang.
Note that it requires Administrator previlage.
Now enter this command to start rabbitmq-server:
rabbitmq-server start
Every time you restart your computer you should do these steps.For prevent do them again you should stop rabbitmq service from startup services.
went through same problem in windows, it is already running after installation as a service
so just enable the plugins from the rabbitmq commandline by entering the code as
rabbitmq-plugins enable management_plugin
than go to the localhost:15672 and good to go.
This means that your port 25672 is already in use
try: -
sudo lsof -i :25672
sudo kill <PID>
and now start your rabbitmq server using
sudo rabbitmq-server
I am trying to setup a wifihotpot on my laptop in ubuntu 18 running as a Windows Subsystem for Linux (WSL). (Terminal only)
Following basic tutorials I wanted to run the following command:
~$ nmcli device wifi hotspot con-name my-hotspot ssid my-hotspot band bg password 123456
Error: Could not create NMClient object: Could not connect: No such file or directory.
Trying to start the networkmanager also fails:
~$ sudo service network-manager start
* Starting network connection manager NetworkManager [ OK ]
~$ sudo service network-manager status
* NetworkManager is not running
I tried the networkManager after installing network-manager:
sudo add-apt-repository ppa:nilarimogard/webupd8
Is there another way to create a wifi hotspot from Ubuntu running as a WSL? Or does it not have the right access to the windows host to pull it off?
at this time, I don't believe it is possible according to https://github.com/microsoft/WSL/issues/2438. They designed WSL to ignore calls to set interface properties. So nmcli and other commands that changes interface properties are not working, they marked it as a bug and will fix it in the future.

I hope to help in some way :)
Host OS: Windows 10
Vagrant: 2.2.4
VirtualBox: 6.0.6 r130049
When I run vagrant up, it prints this error message:
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
setup
Stdout from the command:
Stderr from the command:
bash: line 4: setup: command not found
The machine can be booted normally and SSH from my host to Virtual machine is OK but the synced folder is not working. I know this may not be a critical issue but still feel frustrated as I use my host machine to develop codes and "sync" these codes so that they can be loaded in my virtual machine.
Any advice is highly appreciated.
ps: When I boot a full UI virtual machine (different from my above mentioned) from my VirtualBox directly, it seems OK to have a "sync" directory and the VBGuestAdditions can be installed without errors.
It is a bug in VirtualBox 6.0.6 and it still exists in 6.0.8. The solution is to downgrade your VirtualBox itself and the Guest Extensions to 6.0.4.
I'm trying to run activemq on my ubuntu virtual machine but have constantly been running into issues getting it to start up. I've tried downloading the binary and source with no luck. Currently I have downloaded the source, run "mvn clean install -Dmaven.test.skip=true" and mvn reported successful installation. I then hunted around in my .m2 folder found apache-activemq-5.5.1-bin.tar.gz and extracted it to my home/USERNAME dir and attempted to run "bash bin/activemq start" only to receive the following error.

exit $RET: No such file or directory
Has any one run into this type of error before?
Looks like I'm answering one of my questions again, but maybe this will help someone in the future.
steps.
I ended up getting activemq to work by creating a configuration file via running the command "./bin/activemq setup newConfig" (exclude the quotes)
I then replaced the current config file "activemq" which was located at etc/default/. (I made a backup of the original activemq file before overwriting it with newConfig).
Run "./bin/activemq start" which will create a PID file.
After the file is created re-run "./bin/activemq start" to finally start up the broker.
You can then test the install by navigating to "http://localhost:8161/admin/" or by doing a "netstat -an | grep 61616" if you kept the default ports etc.
I install activemq 5.13 on Debian, download and unzip in /opt, then I go to /opt/apache-activemq-5.13.1/run "./bin/activemq start", then appear this error:

echo "INFO: pidfile created : '/opt/apache-activemq-5.13.1//data/activemq.pid' (pid '$APID')";exit $RET: not found
What I did is to check the Debian version using "uname -a":
Linux debian 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u3 (2016-01-17) x86_64 GNU/Linux
I found my debian is 64 bit system. so I run
./bin/linux-x86-64/activemq start
It shows:
Starting ActiveMQ Broker...
Then I can access the site:http://localhost:8161/admin/ with username "admin" and password "admin"
with Ubuntu 14.04, I had to create a link in /etc/activemq/instances-enabled
sudo ln -s ../instances-available/main/
similar to apache2 setup
then started the server with /etc/init.d/activemq start
sudo is necessary.
bin$ sudo ./activemq start
bin$ sudo ./activemq status
INFO: Loading '/opt/runtime/apache-activemq-5.11.1/bin/env' INFO: Using java '/usr/bin/java' ActiveMQ is running (pid '29887')
