Hi all,
I received this e-mail from Christer regarding dead links in the CentOS
8.1911 release notes.
Can the maintainer of the CentOS 8 release notes determine what the best
course of action is?? Thanks.
Regards,
Timothy

Subject: Update CentOS wiki 8.1 Release notes
Date: Fri, 7 Feb 2020 11:03:42 +0100
From: Christer M. Fekjan <christer.centos-e216w at fekjan.no>
To: Timothy Lee <timothy.ty.lee at gmail.com>
Hi Timothy!
I discovered three link errors (404s) in the 8.1. release notes. I
registered a user for the wiki, downloaded and edited the file. As I
have no update credentials, I hereby attach the updated file and kindly
ask you to update the wiki. Of course I could always do that myself if
I'm given the necessary credentials.
I also attach a diff file. As you can see I suggest to move the link for
known issues forward in the sentence, from "RHEL 8.1 release notes" to
"known upstream issues". Just to let you know in case you have a
different opinion and want to keep that unchanged.
Thank you in advance, and have a great day!
Kind regards,
Christer Michaelsen Fekjan

== Introduction =
### '''This page is Work In Progress!'''
### {{{#!wiki tip
### '''Attention''' [[BR]]Currently this release is just
into the [:AdditionalResources/Repositories/CR:Continuous Release (CR)
repository] for CentOS-7 (1804). To install CR, you can use the command
'''yum-config-manager --enable cr'''. You can then
upgrade CentOS-7 installations to the CentOS-7-CR packages using the command
'''yum upgrade'''. Please read the information about the
[:AdditionalResources/Repositories/CR:CR repository] if you are unfamiliar with
what it is. As explained there, we are still doing advanced QA testing on the
next release and there may be some minor changes before the final. This
''opt-in'' process allows you earlier access to our best effort
packages now while we complete the final QA processes, spin the ISOs and create
an installable tree. As already mentioned, these Release Notes are to be
considered as work-in-progress.
### }}}
{{{#!wiki caution
The CentOS Project '''does not''' provide any
verification, certification, or software assurance with respect to security for
CentOS Linux. The '''Security Profiles''' provided in
the CentOS Linux installers are a conversion of the ones included in RHEL Source
Code. If certified / verified software that has guaranteed assurance is what you
are looking for, then you likely do not want to use CentOS Linux. See this
[[TipsAndTricks/C7SecurityProfiles|link]] if you plan to use Security Profiles.
}}}
Hello and welcome to the second CentOS-8 release. The CentOS Linux distribution
is a stable, predictable, manageable and reproducible platform derived from the
sources of Red Hat Enterprise Linux (RHEL)<<FootNote(Visit
https://www.redhat.com/rhel/)>>. You can read our official product
announcement for this release.
CentOS conforms fully with Red Hat's redistribution policy and aims to have
full functional compatibility with the upstream product. CentOS mainly changes
packages to remove Red Hat's branding and artwork.
We have decided not to follow Red Hat's usage of Installation Roles. In
CentOS Linux all content from every distribution 'channel' is made
available to the user at time of installation.
###There is a documented and recommended upgrade path from CentOS-7 to CentOS-8
however this tooling is currently broken and should not be used. For more
information on how the upgrade procedure should work please take a look at
[https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Migration_Planning_Guide/chap-Red_Hat_Enterprise_Linux-Migration_Planning_Guide-Upgrading.html
upstream documentation]. The tools needed for this functionality are currently
broken and should not be used. If you can help with the fixing the upgrade
tools, please see this CentOS-Devel mailing list
[https://lists.centos.org/pipermail/centos-devel/2014-July/011277.html thread]
and this [:TipsAndTricks/CentOSUpgradeTool:wiki entry].
###The [:AdditionalResources/Repositories/CR:continuous release (CR) repository]
makes generally available packages that will appear in the next point release of
CentOS, on a testing and hotfix basis until formally released.
Please read through the other sections before trying an install or reporting an
issue.
This is the second release of a new distribution from the CentOS Project:
[[https://wiki.centos.org/Manuals/ReleaseNotes/CentOSStream|CentOS Stream]].
CentOS Stream is a rolling-release Linux distro that exists as a mid-stream
between the upstream development in Fedora Linux and the downstream development
for Red Hat Enterprise Linux (RHEL). It is a cleared-path to contributing into
future minor releases of RHEL while interacting with Red Hat and other open
source ecosystem developers. This pairs nicely with the existing contribution
path in Fedora for future major releases of RHEL. You can read more on the
[[https://wiki.centos.org/Manuals/ReleaseNotes/CentOSStream|CentOS Stream
release notes page]].
== Install Media =### {{{#!wiki caution
### While in CR (see above) there are no install media, only upgrades of current
installs via yum are possible
### }}}
Various installation images are available for installing CentOS. Which image you
need to download depends on your installation environment. All of these images
can either be burned on a DVD or dd?ed to an USB memory stick.
'''If you are unsure which image to use, pick the DVD
image.''' It allows selecting which components you want to install
and contains all packages that can be selected from the GUI installer.
The boot image can be used for doing installs over network. After booting the
computer with this image, the installer will ask from where it should fetch the
packages to be installed.
{{{#!wiki tip
'''Attention''' <<BR>>At least 2 GB RAM are
required to install and use CentOS-8 (1911). At least 4 GB RAM is recommended.
[[https://bugs.centos.org/view.php?id=8353|Bug 8353]]

== Verifying Downloaded Installation Images =Before copying the image to your
preferred installation media you should [[TipsAndTricks/sha256sum|check the
sha256sum]] of the downloaded installation images.

build from the same sources, many, if not all, of those issues will likely also
apply to CentOS Linux.
{{{#!wiki caution
If you are planning to install CentOS-8 in a !VirtualBox guest, you should not
select "Server with a GUI" (default) during the installation. See this
[[https://developers.redhat.com/rhel8/install-rhel8-vbox|Red Hat article]] for
details.
}}}
{{{#!wiki caution
Support for some adapters has been removed in CentOS-8. You can find the device
IDs of those adapters in this
[[https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/considerations_in_adopting_rhel_8/hardware-enablement_considerations-in-adopting-rhel-8#removed-adapters_hardware-enablement|upstream

[[https://elrepo.org/linux/dud/el8/x86_64/|driver update disks (DUD)]] for some
of those that are still commonly used. For the list of the device IDs provided
by the ELRepo packages, please see [[http://elrepo.org/tiki/DeviceIDs|here]].
Some more details are in
[[https://elrepoproject.blogspot.com/2019/08/rhel-80-and-support-for-removed-adapters.html|this
blog]]. Note also that, once CentOS-8 is installed, you can use the centosplus
kernel ('''kernel-plus''') which has support for those
devices.
}}}
{{{#!wiki caution
If you are using the boot.iso and NFS to install, the automatic procedure for
adding the !AppStream-Repo will fail. You have to disable it and add the right
NFS-path manually.
}}}
{{{#!wiki caution
The dotnet2.1 component is incomplete on the DVD ISO and in the kickstart/ repo.
A system upgrade from 8.0.1905 should result in a complete upgrade, but new
users of dotnet should avoid installing dotnet from the distribution installer.
}}}
{{{#!wiki tip
Installing the !VirtualBox Addons will produce an error if your version is
6.0.12/5.2.32 or lower. This is fixed with versions 6.0.14 and 5.2.34
}}}
{{{#!wiki tip
!PackageKit is unable to resolve local DNF/YUM variables. As a result
!PackageKit will not function if these variables are in use. We are tracking
[[https://bugs.centos.org/view.php?id=16446|this bug]].
}}}
{{{#!wiki tip
Installing CentOS 8 in !VirtualBox 5.2.32 (maybe other versions too) will do
weird things with the graphical install screen towards the end of the
installation. This makes it impossible to see the install status or press the
reboot button and you have to guess when the install is finished. The screen
corruption can be cleared by switching to a different terminal and back using
the vbox Host key + 2 to switch to VT 2 and then vbox Host key + 6 to switch
back to the graphical install screen.

== Sources =All CentOS-8 sources are hosted at
'''git.centos.org'''. All code released into the
distribution originated from git.centos.org.
Source RPMs will also be published once the release is done, in the usual
location at http://vault.centos.org/centos/8/
>From a CentOS machine you can easily retrieve sources using the
''yumdownloader --source <packagename>'' command.
##begin-help
== How to help and get help =As a CentOS user there are various ways you can
help out with the CentOS community. Take a look at our [[Contribute]] page for
further information on how to get involved.
=== Special Interest Groups ==CentOS consists of different
[[SpecialInterestGroup|Special Interest Groups]] (SIGs) that bring together
people with similar interests. The following SIGs already exist (among others):
* [[SpecialInterestGroup/Artwork|Artwork]] - create and improve artwork for
CentOS releases and promotion
* [[SpecialInterestGroup/Promo|Promotion]] - help promoting CentOS online or at
events
* [[SpecialInterestGroup/Virtualization|Virtualization]] - unite people around
virtualization in CentOS
And we encourage people to join any of these SIGs or start up a new SIG, e.g.
* ARM, PPC and i386 port - help with porting CentOS to other architectures
* Hardware compatibility - provide feedback about specific hardware
* RPM Packaging - contribute new useful RPM packages
* Translation - help translating the documentation, website and Wiki content
=== Mailing Lists and Forums ==Another way you can help others in the community
is by actively helping and resolving problems that users come up against in
[[https://lists.centos.org/mailman/listinfo|the mailing lists]] and
[[https://www.centos.org/forums/|the forums]].
=== Wiki and Website ==Even as an inexperienced CentOS user we can use your
help. Because we like to know what problems you encountered, if you had problems
finding specific information, how you would improve documentation so it becomes
more accessible. This kind of feedback is as valuable to others as it would have
been to you so your involvement is required to make CentOS better.
So if you want to help out and improve our documentation and Wiki,
[[Contribute#head-42b3d8e26400a106851a61aebe5c2cca54dd79e5|register on the
Wiki]] or subscribe to the
[[https://lists.centos.org/mailman/listinfo/centos-docs|centos-docs]] mailing
list.
=== IRC Presence ==The CentOS project maintains a presence on the freenode IRC
network as an additional venue for community support and interaction. Please
see our [[irc|IRC wiki article]] for more information.
== Further Reading =The following websites contain large amounts of information
to help people with their CentOS systems:

== Thanks =We thank everyone involved for helping us produce this product and
would like to specifically acknowledge the extra effort made by the QA Team.
Without them working lots and lots of hours in evenings, nights, weekends and
holidays, we couldn't have released this Release in the time we did. A
special thanks also goes to the CentOS-community. A more complete list of the
contributors to this release can be found at
/usr/share/doc/centos-release/Contributors of your new CentOS-8 installation.
