Ubuntu 18.04 LTS

Versie 18.04 van Ubuntu Linux is uitgekomen, een versie met extra lange ondersteuning. Tweemaal per jaar verschijnt er een nieuwe versie en vormen het jaar en de maand van uitgave het versienummer. Eens in de twee jaar komt er een versie uit die niet negen maanden maar vijf jaar voorzien zal worden van updates. Versie 18.04 heeft codenaam Bionic Beaver meegekregen en draait op Linux Kernel 4.15. Afgezien van bijgewerkte programma’s is er ten opzichte van versie 17.10 niet zoveel veranderd. Wel heeft X.Org weer de voorkeur gekregen boven Wayland. De complete release notes zijn op deze pagina in te zien, dit is een kort stuk daaruit:

Updated Packages

Linux kernel 4.15
Ubuntu 18.04 ships with a v4.15 based Linux kernel, enabling the latest hardware and peripherals available from IBM, Intel, and others. The 18.04 kernel delivers new features inherited from upstream, including:

  • CPU controller for the cgroup v2 interface
  • AMD secure memory encryption support
  • The latest MD driver with software RAID enhancements
  • Improved power management for systems with SATA Link Power Management

We also see notable Ubuntu specific achievements with:

  • Linux security module stacking support
  • Support for signing of POWER host and NV kernels
  • Backport improved support for IBM and Intel hardware from Linux 4.16

OpenJDK
As of 18.04 release, OpenJDK 10 is the default JRE/JDK. Once OpenJDK 11 reaches GA in September 2018, it will become the default in 18.04.

Microsoft’s Newest OS is Based on Linux

microsoft loves linux

Microsoft loves Linux so much that it has gone and made its very own, custom Linux kernel.

I joke you not!

‘Microsoft loves Linux so much it has made its own, custom Linux kernel’

Announcing the (somewhat unbelievable) news at an event in San Francisco, USA on April 16, Microsoft President Bad Smith said:

“After 43 years, this is the first day that we are announcing, and will be distributing, a custom Linux kernel.”

No, it’s not April 1. No, he’s not joking.

Microsoft is using Linux as part of a new product called Azure Sphere.

Azure Sphere is a new bit of technology from Microsoft designed to protect micro-processors used in small devices and the ‘internet of things’, as this video explains:

Installing a root/CA Certificate and sloved Citrix SSL 61 Error

 

 

 

Given a CA certificate file certificate.crt, follow these steps to install it on Ubuntu:

  1. Create a directory for extra CA certificates in /usr/share/ca-certificates:
    sudo mkdir /usr/share/ca-certificates/extra
    
  2. Copy the CA .crt file to this directory:
    sudo cp certificate.crt /usr/share/ca-certificates/extra/certificate.crt
    
  3. Let Ubuntu add the .crt file’s path relative to /usr/share/ca-certificates to /etc/ca-certificates.conf:
    sudo dpkg-reconfigure ca-certificates
    

In case of a .pem file on Ubuntu, it must first be converted to a .crt file:

openssl x509 -in certificate.pem -inform PEM -out certificate.crt

For Citrix Reciever:
sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts
