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

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.

== Major Changes ==
See the [[https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/8.1_release_notes/overview|Overview section]] of upstream Release Notes.

== Deprecated Features ==
See upstream documentations for [[https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/8.1_release_notes/rhel-8_1_0_release#deprecated_functionality|Deprecated functionality]] and [[https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/considerations_in_adopting_rhel_8/security_considerations-in-adopting-rhel-8#removed_security_functionality|Removed security functionality]].

== Known Issues ==
A list of [[https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/8.1_release_notes/rhel-8_1_0_release#known-issues|known upstream issues]] can be found in the RHEL 8.1 release notes. Given that we 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 documentation]]. [[http://elrepo.org|ELRepo]] offers [[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.
