>>> Failed to install dev-lang/go-1.13.4, Log file:

>>>  '/var/tmp/portage/dev-lang/go-1.13.4/temp/build.log'

The above log shows that the emerge fails in the installation phase when moving the files to the proper path in the system. The problem there is a non-ASCII character in the file name or path, but the environment is set to use ASCII as language.

The solution is to check if the environment LANG is set and what it contains. In this case, we should set the LANG environment to utf8.

export LANG=en_US.UTF-8

Most of the cases this kind of error could occur with virtual servers, docker (or the other kind of containers like lxc, podman and so on) containers and chroot jails or screens with changed user with su or sudo! In our case, the LANG just got missed because of a switch user procedure in a container and the emerge failed with the above error. When the LANG is missing probably the default value is “C”. In fact, check not only LANG but also the “LC_ALL” environment variable (it may have different value, which is wrong!), which also should be “en_US.UTF-8”:

export LC_ALL=en_US.UTF-8

Or try removing it at all with

unset LC_ALL

Install Fedora Workstation 31 (Gnome GUI)

This tutorial will show you the simple steps of installing a modern Linux Distribution like Fedora 31 Workstation with Gnome for the user graphical interface. First, we present the basic steps for installing the Operating system in addition to your present operating systems (here we also have Windows 10) and then you can see some screenshots of the installed system and the look and feel of it. We have other tutorials showing more screenshots of the installed and working Fedora 31 (Gnome and KDE plasma) – so you can decide which of them to try first – coming soon.

The Fedora 31 Workstation comes with

  • Xorg X server – 1.20.5 XWayland is used by default
  • GNOME (the GUI) – 3.34.1
  • linux kernel – 5.3.7

Check out our article about what software is included in comming soon.

The installation process is very similar to the old Fedora Workstation 27, Fedora Workstation 28, Fedora Workstation 29, Install Fedora Workstation 30 (Gnome GUI) , in fact the main difference is the creation of an user, which the setup is not responsible anymore, the creation of an user is done by the first boot after installation. Our system was pretty good – Asus X399 with AMD Ryzen Threadripper 1950X and NVIDIA 1080 Ti and the setup loaded successfully and there were no problems till the end.

We used the following ISO for the installation process:

https://download.fedoraproject.org/pub/fedora/linux/releases/31/Workstation/x86_64/iso/Fedora-Workstation-Live-x86_64-31-1.9.iso

It is a LIVE image so you can try it before installing. The easiest way is just to download the image and burn it to a DVD disk and then follow the installation below:

SCREENSHOT 1) Here is our “UEFI BIOS->Boot->Boot Override” and in most modern motherboard you can choose to override the default boot devices.

Choose the “UEFI: HL-DT-STDVDRAM…” to boot and install Fedora Workstation 31 with UEFI support. You should do this, because most of the new hardware like video cards would not work properly without beeing in UEFI mode.

Install CentOS 8 over the old OS and preserve the storage partitions

Always put your root partition separate from the storage (aka data) partitions. root partition should be only for system files and nothing more! Keeping this simple rule you may easily change your operating system (or clean install or clean upgrade) without deleting the user’s data thus preserving the old storage partitions.
Our storage has 2 storage partitions, which means they hosts only data and no system files and there are separate partitions for Linux booting (grub2) and system files (root partition). Here is the partitions layout:

[root@srv0 ~]# parted /dev/sda --script print

tmpfs           3.2G     0  3.2G   0% /run/user/0

Of course, when there are partitions above 2T the GPT is mandatory.
You can skip the software RAID1 setup if you use only one controller or you have system partitions only in one disk (virtual drive and so on). Here we have two hardware controllers, which we want to use both for the system partitions.
4 RAID1 devices:

  1. EFI partition (/boot/efi)
  2. swap partition
  3. boot parition (/boot)
  4. root partition (/)

The best practice is have total between 30G and 50G for the 4 partitions (in fact, boot partition could be skipped). Have in mind most modern Linux distributions cannot be installed on less than 10G~20G and for optimal results just separate between 30G and 50G for 4 partitions above (or 3 if you choose to skip the boot one).

Upgrade to CentOS 8 with clean install over our old CentOS 7 system partitions preserving the big data partitions.

Couple of things before start:

  • UEFI installation will be selected. So boot in UEFI mode.
  • IPMI KVM is used to install the new Linux distribution – CentOS 8
  • The installation disk is mounted in the Virtual CD/DVD IPMI KVM device – with Mount and boot ISO file from windows share in Supermicro IPMI Virtual media (CD-ROM)
  • All system parititions will be removed (grub, boot, root) and a clean minimal installation will be performed.
  • Network installation – using CentOS-8-x86_64-1905-boot.iso

SCREENSHOT 1) The Server is starting. This is the IPMI KVM window. Press F11 to Boot in Boot Menu.

How to do a network installation of CentOS 8 (8.0.1950) – minimal server installation

Minimal net install is useful when a dedicated server is installed from a IPMI KVM or Dell iDRAC, HP iLO, IBM IMM or where the initial client side download of files need to be minimal.
For amd64 CentOS 8 BaseOS the net install bootable media is located here (now the current latest release is 8.0.1950, but you can check the last directory with 8. for the time you follow this howto):

http://mirror.leaseweb.com/centos/8/isos/x86_64/CentOS-8-x86_64-1905-boot.iso

Note there is no minimal CD for offline installation anymore. Boot CD is to just boot and make “netinstall” installation and a big fat DVD of 6.6Gbytes to install offline.
Software details of CentOS 8 minimal install could be found here – Technical details of a default CentOS 8.0.1950 minimal installation

Download it and put it on a cd or usb, the boot from it and follow the steps bellow:

STEP 1) Enter the BIOS of your machine (desktop or server) to change the boot order.

You can try F11 on most servers to have the boot menu. Here we use DEL to enter the UEFI BIOS.

Minimal quagga bgpd configuration to run and remote configure it

There are the three steps to configure your Quagga bgpd daemon to be able to run and configure remotely. The idea of this article is to show you how you can run the quagga bgpd with the minimal configuration and probably you might give the credential to a network administrator.
Summary – 3 files to change:

  1. /etc/quagga/daemons – enable BGPD daemon
  2. /etc/quagga/debian.conf – which IP to listen to
  3. /etc/quagga/bgpd.conf – BGP daemon configuration

Access Violation error when compiling packets in Gentoo – symlink

Here is another example of Access violation error when building packages in Gentoo. This time the build process could not make a symbolic link in “/usr/bin” and the build process of the package failed with:

 * ACCESS DENIED:  symlink:      /usr/bin/stransmit
CMake Error: failed to create symbolic link '/usr/bin/stransmit': permission denied

A detail explanation is available in our first article on the subject here – Access Violation error, when compiling packets in Gentoo.
All packages are built in a sandbox and there is a sandbox configuration in

/etc/sandbox.d/00default

, which instruct the build process where could write. If you get such error in 99.99% there is a bug in the package and if you do not want to wait for fixing it (report it!) you can manually edit the SANDBOX_WRITE variable and add the path, which causes the build failure. Build the package and remove the added path!!! Or you risk to make your system less secure!

In the installation phase occurred the package failure leaving half installed package. So we edited the “/etc/sandbox.d/00default” and added “:/usr/bin” at the end of SANDBOX_WRITE:

SANDBOX_WRITE="/usr/tmp/conftest:/usr/lib/conftest:/usr/lib32/conftest:/usr/lib64/conftest:/usr/tmp/cf:/usr/lib/cf:/usr/lib32/cf:/usr/lib64/cf:/usr/bin"

Then rebuild the package with emerge and remove the added path “:/usr/bin”. This is a dirty workaround, but it will allow you to use srt (and as a dependency to another packages’ installation).

Our system was pretty new – Asus X399 with AMD Ryzen Threadripper 1950X and NVIDIA 1080 Ti and the setup loaded successfully and there were no problems till the end.

We used the following ISO for the installation process:

https://download.fedoraproject.org/pub/fedora/linux/releases/29/Workstation/x86_64/iso/Fedora-Workstation-Live-x86_64-29-1.2.iso

It is a LIVE image so you can try it before installing. The easiest way is just to download the image and burn it to a DVD disk and then follow the installation below:

STEP 1) Here is our “UEFI BIOS->Boot->Boot Override” and in most modern motherboard you can choose to override the default boot devices.

Choose the “UEFI: HL-DT-STDVDRAM…” to boot and install Fedora Workstation 29 with UEFI support. You should do this, because most of the new hardware like video cards would not work properly without beeing in UEFI mode.

Manual install of base Gentoo Linux x86_64 with openrc (init) and uefi using minimal installation cd

Here we are going to show the minimum steps to install a base Gentoo Linux on your computer – server or desktop using “Minimal Installation CD”.
The installation ISO CD is generated on 11.09.2018, but you can use an older or newer one, this guide uses commands, which are available in really old ISOs (10 years ago) and probably will be available in the future, too! The idea is not to change this ISO a lot and to have only the basic tools for installation, which should be the same for a really log time! If you need more tools there two other options: Hybrid IS0, which is a LiveDVD – a system with GUI and Admin CD, which is extended version of the minimal installation CD (no GUI).

Our base Gentoo system will use:

  1. OpenRC, which is based on init to boot the server. This is the default in Gentoo, but you might have problems using Gnome
  2. GRUB 2 UEFI enabled and the server will be booted in UEFI mode. Recently most of the desktop machine and server support it and in many cases it is mandatory to use a new hardware.
  3. No GUI will be installed (KDE, Gnome, Xfce and so on), there are other tutorials for this, you can check here (coming soon)
