A connection to the notebook server could not be established

While pip installing tensorflowjs in my local computer this happened.
I have tried restarting kernel.
In the Firefox console following error is shown:
Firefox Console Error Image
I have no clue regarding this problem.
This solution worked for me:
pip install "ipykernel<5.0.0"
But many suggested that this also helped them:
pip install prompt-toolkit==3.0.5
This also worked for some people:
pip install -U jupyter_console
I faced same issue. When tensorflowjs was installed, prompt-toolkit version was downgraded. Run below code in anacoda command prompt:
pip install prompt-toolkit==3.0.5

Error while installing tripleo Client Library

When i try to download tripleo Client using command
yum install -y python-tripleoclient ceph-ansible
On Centos 7.5 , I am getting error curl#60 - "Peer's Certificate has expired."
This has nothing to do with tripleo client itself. You are using some temporary yum repositories which were recycled.
My favorite hacking approach is to use pip to install it:
pip install python-tripleoclient
This is also documented on https://docs.openstack.org/python-tripleoclient/latest/installation.html

Nginx+Passenger Error - libcurl.so.4: version `CURL_OPENSSL_3' not found

System:
Ubuntu: 18.04 LTS
Passenger: 5.3.1
nginx with libnginx-mod-http-passenger
$ sudo nginx -t
Returns:
PassengerLoggingAgent: /usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by PassengerLoggingAgent)
2018/06/04 02:28:40 [alert] 10411#0: Unable to start the Phusion Passenger watchdog because it encountered the following error during startup: Unable to start the Phusion Passenger logging agent: it seems to have crashed during startup for an unknown reason, with exit code 1 (-1: Unknown error)
```
You can install the required version 3 from the bionic repository if you don't depend on other software that already uses version 4:
sudo apt install libcurl3/bionic
This will ask you to remove curl itself, libcurl4, and dependend software. Consider carefully if you need those, before removing them.
You still can roll back by installing libcurl4 and the removed software again.
This fixed my problem:
sudo apt install libcurl4-openssl-dev

GNS3 sip/qt error

Have installed GNS3 on my Linux (Debian Strech) and getting below error message, please help, installed from package, OS updated. qt and sip at their newest version on my machine (installed).
Fail update installation: No module named 'sip' **
**Can't import Qt modules: Qt and/or PyQt is probably not installed correctly...
Any help/direction to solve the problem will be highly appreciated.
Thanks in-advance.
For anyone still getting this error, I found that it was due to Xenial to Bionical upgrade that left a PPA hanging around, I guess there was a dependency missing. Here is exactly what I did to fix it.
sudo rm /etc/apt/sources.list.d/gns3*
sudo apt-get update
sudo add-apt-repository ppa:gns3/ppa
sudo apt-get update
sudo apt-get -y -u dist-upgrade
Then you can start gns3.
Try to install this python module:
sudo pip install pyqt5
i found out that the problem was a source in source.list.
in my case was the firefox quantum
I resolved this by installing from source file, by following this link, replaced 1.3.9 to 2.1.2 and worked.
https://gns3.com/discussions/getting-gns4-1-4beta1-gui-runnin
I got this after upgrading Ubuntu to 20.04. Only thing that worked was backing up my GNS3 folder with my project files, uninstalling gns3-server and gns3-gui, then re-installing. Everything works now.

Installing SaltStack on RHEL 7?

I need help on installing saltstack on RHEL 7.
RHEL 7 server is from AWS Amazon.
$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.0 (Maipo)
I'm getting an error during installation:
$ wget -O - http://bootstrap.saltstack.org | sudo sh
2014-08-04 09:41:45 (932 KB/s) - written to stdout [177548/177548]
INFO: Found function install_red_hat_enterprise_linux_7_stable_deps

ERROR: Stable version is not available on RHEL 7 Beta/RC. Please set installation type to git.
ERROR: Failed to run install_red_hat_enterprise_linux_7_stable_deps()!!!
Is this version of RHEL 7 not supported for saltstack?
Run the following commands to install from the latest develop branch:
curl -o install_salt.sh -L https://bootstrap.saltstack.com
sudo sh install_salt.sh -M git develop
Remove the -M from the command above if you don't want to install a salt-master and only want to install salt-minion.
I have a similar problem, I tried to install it from epel 7 beta, but there's another problem, see https://bugzilla.redhat.com/show_bug.cgi?id=1127348. Finally I was able to install it by combining pip and yum. I don't have the exact sequence of commands, but sth. like this should work:
yum install --skip-broken salt python-pip
pip install jinja2
I have tried installing SaltStack on CentOS 7 , which should be similar to Redhat 7, and you could try it, hope it works for you:
**[updated]** http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm
and then you could
yum install -y salt-master
or
yum install -y install salt-minion
to install it.
You need to enable the rhel-7-server-optional-rpms repo in subscription-manager.
