404 GET error message MathJax

404 GET /static/components/MathJax/MathJax.js?config=TeX-AMS-MML_HTMLorMML-full,Safe&delayStartupUntil=configured
I can't open a notebook because I continually receive this error message. I just installed Fedora in my laptop, installing things from scratch and have been failing with jupyter notebook installation, my main resource for work. I tried looking it up, spent hours trying to find a solution (reinstalled jupyter, made a virtual machine,tried a different browser, edited the jupyter-notebook-config.py file) and nothing seems to work. I have zero clue on how to interpret this error message. Can someone please help???
sudo dnf install mathjax fixed the issue for me in Fedora 28 rpm package install (there are guides on how to do it at https://fedoralovespython.org/). They should have made mathjax a dependency in sudo dnf install python3-notebook.

Unable to locate package libvirt-clients error on ubuntu

I am seeing the below error when deploying devstack (openstack) on ubuntu:
E: Unable to locate package libvirt-clients
E: Unable to locate package libvirt-daemon-system
Any clues pls ?
I have this problem too and i use ubuntu trusty
according to this commit:
https://github.com/openstack-dev/devstack/commit/03fbc0d71bf4ee85820999ef1324dc319ef9d926?diff=split
they changed the repo packages 5 days ago and just for ubuntu xenial its the same as before : "install_package libvirt-bin libvirt-dev"
but other distros: "install_package libvirt-clients libvirt-daemon-system libvirt-dev"
I think we could better edit the file manually until better changes take place.
You're probably trying to install Devstack it on an unsupported version of Linux. Try Ubuntu 16.0.4 (worked for my today without a single problem) or the one that the installation guide says is supported.
Try sudo apt install qemu qemu-kvm virt-manager for more information check this out on github.

Atom-editor beautify gives php-cs-fixer error

I'm pretty much new to Atom editor, but setup some nice packages like Atom Beautify. After using it in a html / php file I'm getting the error "Could not find 'php-cs-fixer' . The program may not be installed. The strange thing is, I did install the package php-cs-fixer but nothing happens.
Anyone got an idea how I can fix this?
Thanks in advance,
OK, for the not programmers here:
I installed php-cs-fixer via Brew for mac . Brew enables (wget) command lines via terminal. After installing brew, type brew install homebrew/php/php-cs-fixer in terminal and it will install the PHP-CS-Fixer .
Done!

Failed to install R on Centos 7

I have CentOS 7 (3.10.0-123.el7.x86_64) and I seem not be able to install R and then get Rstudio server working.
This is what I did:
rpm -Uvh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum install R
Then I got this error:
Transaction check error:
file /usr/lib/systemd/system/blk-availability.service from install of device-mapper-7:1.02.107-5.el7_2.1.x86_64 conflicts with file from package lvm2-7:2.02.105-14.el7.x86_64

I am not sure what it is. There is nothing from whereis R because it didn't install.
If I install Rstudio Server, it would fail to start the service and said ERROR unable to find installation of R in the system
Can someone tell me how to install R properly on Centos 7?
That is not related to R. Your log shows a conflict between "device-mapper" and "lvm2", and these packages are used to operate with devices such as hard disks and partitions (before someone downvotes me, YES this is a crude simplification).
You should try to update your system with yum before installing R.
I resolved this problem by updating lvm2 firstly, then install R.
This idea was from: https://bugzilla.redhat.com/show_bug.cgi?id=1294128

Octave Installation Failing on Mac OS X Yosemite

I am trying to install octave through brew on mac (10.10.5 Yosemite). The command used is brew install octave . While installing, the process tries to install qt (version 4.8.7) which is essentially failing with the below error
Error : 'File already exists. /usr/local/Cellar/qt/4.8.7'.
When I check the file at this particular location, I don`t see any such directory, though the directory does appear and is created during the installation (probably getting removed later when the task fails).
Could someone please point out what I need to do exactly? Is Qt really required for Octave installation? If not then any way to skip it?
