It needs an architecture and then some additional pathing to get to packages. After adding the C6.10 entries to the Vault repo did you turn off the entries (e.g., set "enabled=" to "0") in the non-vault repos? If you don't yum will still try them. The CentOS-Base.repo is on by default so you'll either need to add the "enabled=" line to each of the entries or otherwise disable the repos.

Today's Topics: 1. Release for CentOS Linux 8 (2011) (Brian Stinson) ---------------------------------------------------------------------- Message: 1 Date: Mon, 7 Dec 2020 15:06:36 -0600 From: Brian Stinson <bstinson(a)centosproject.org> To: centos-announce(a)centos.org Subject: [CentOS-announce] Release for CentOS Linux 8 (2011) Message-ID: <85a40c22-dad9-f6d5-c123-d4126039f965(a)centosproject.org> Content-Type: text/plain; charset=utf-8 Release for CentOS Linux 8 (2011) We are pleased to announce the general availability of CentOS Linux 8. Effectively immediately, this is the current release for CentOS Linux 8 and is tagged as 2011, derived from Red Hat Enterprise Linux 8.3 Source Code. As always, read through the Release Notes at: http://wiki.centos.org/Manuals/ReleaseNotes/CentOS8.2011 - these notes contain important information about the release and details about some of the content inside the release from the CentOS QA team. These notes are updated constantly to include issues and incorporate feedback from users. ---------- Updates, Sources, and DebugInfos Updates released since the upstream release are all posted, across all architectures. We strongly recommend every user apply all updates, including the content released today, on your existing CentOS Linux 8 machine by just running 'dnf update'. As with all CentOS Linux 8 components, this release was built from sources hosted at git.centos.org. Sources will be available from vault.centos.org in their own dedicated directories to match the corresponding binary RPMs. Since there is far less traffic to the CentOS source RPMs compared with the binary RPMs, we are not putting this content on the main mirror network. If users wish to mirror this content they can do so using the reposync command available in the yum/dnf-utils package. All CentOS source RPMs are signed with the same key used to sign their binary counterparts. Developers and end users looking at inspecting and contributing patches to the CentOS Linux distro will find the code hosted at git.centos.org far simpler to work against. Details on how to best consume those are documented along with a quick start at: http://wiki.centos.org/Sources Debuginfo packages have been signed and pushed. Yum configs shipped in the new release file will have all the context required for debuginfo to be available on every CentOS Linux install. This release supersedes all previously released content for CentOS Linux 8, and therefore we highly encourage all users to upgrade their machines. Information on different upgrade strategies and how to handle stale content is included in the Release Notes. Note that older content, obsoleted by newer versions of the same applications are trim'd off from repos like extras/ and centosplus/ ---------- Download We produced the following installer images for CentOS Linux 8 # CentOS-8.3.2011-x86_64-boot.iso: 716177408 bytes SHA256 (CentOS-8.3.2011-x86_64-boot.iso) = 2b801bc5801816d0cf27fc74552cf058951c42c7b72b1fe313429b1070c3876c # CentOS-8.3.2011-x86_64-dvd1.iso: 9264168960 bytes SHA256 (CentOS-8.3.2011-x86_64-dvd1.iso) = aaf9d4b3071c16dbbda01dfe06085e5d0fdac76df323e3bbe87cce4318052247 # CentOS-8.3.2011-aarch64-boot.iso: 636792832 bytes SHA256 (CentOS-8.3.2011-aarch64-boot.iso) = b87fc578c53b541229883d391d1299b9d2a051c1f33dc15052dc42ed941600a9 # CentOS-8.3.2011-aarch64-dvd1.iso: 6792984576 bytes SHA256 (CentOS-8.3.2011-aarch64-dvd1.iso) = ecf586b30fa16b28a33b2fb4ffadd8801201608f9755c94da1212876d32fba92 # CentOS-8.3.2011-ppc64le-boot.iso: 686874624 bytes SHA256 (CentOS-8.3.2011-ppc64le-boot.iso) = 13ebdc5ecdfc316fa4528f3bc4d896ca32745af65766bd84ece37e10d87f8e9e # CentOS-8.3.2011-ppc64le-dvd1.iso: 7887482880 bytes SHA256 (CentOS-8.3.2011-ppc64le-dvd1.iso) = a56fc1039534155253ca412fcd8e0293e6f67fd92c526a8b754309578140dff6 Information for the torrent files and sums are available at http://mirror.centos.org/centos/8/isos/ -------- Additional Images Vagrant and Generic Cloud images are available at: http://cloud.centos.org/centos/8/ Amazon Machine Images for Amazon Web Services are published by ID into a number of regions.

Many of the team went further and beyond expectations to bring this release to you, and I would like to thank everyone for their help. We are also looking for people to get involved with the QA process in CentOS, if you would like to join this please introduce yourself on the centos-devel list (http://lists.centos.org/mailman/listinfo/centos-devel). Finally, please join me in thanking the donors who all make this possible for us. Enjoy the fresh new release!

CentOS-8(2011): osbuild - missing selinux subpackage?
by Leon Fauster 08 Dec '20

08 Dec '20

Briefly, while updating some workstation I came across this. The update to CentOS-8(2011) passes without issues (because best=False). So, I guess that all packages landed at the mirror host - but osbuild-selinux is missing? # LANG=C yum update Last metadata expiration check: 0:00:39 ago on Tue Dec 8 01:18:19 2020. Dependencies resolved. Problem: package osbuild-18-3.el8.noarch requires (osbuild-selinux if selinux-policy-targeted), but none of the providers can be installed - package osbuild-composer-20.1-1.el8.x86_64 requires osbuild >= 18, but none of the providers can be installed - cannot install the best update candidate for package selinux-policy-targeted-3.14.3-54.el8.noarch - cannot install the best update candidate for package lorax-composer-28.14.55-2.el8.x86_64 ============================================================================================================================================================================= Package Architecture Version Repository Size ============================================================================================================================================================================= Skipping packages with broken dependencies: osbuild noarch 18-3.el8 appstream 53 k osbuild-composer x86_64 20.1-1.el8 appstream 2.8 M Transaction Summary ============================================================================================================================================================================= Skip 2 Packages Nothing to do.

CentOS 8.2: error running non-shared postrotate script for /var/log/mysql/mysqld.log
by Alexander Farber 08 Dec '20

08 Dec '20

Hello fellow CentOS users! I have installed CentOS 8.2.2004 with the following packages: mysql-common-8.0.21-1.module_el8.2.0+493+63b41e36.x86_64 mysql-8.0.21-1.module_el8.2.0+493+63b41e36.x86_64 mysql-errmsg-8.0.21-1.module_el8.2.0+493+63b41e36.x86_64 mysql-server-8.0.21-1.module_el8.2.0+493+63b41e36.x86_64 Then I have run mysql_secure_installation and among other things set the root password for MySQL As result I am greeted with the following anachron mail every morning: /etc/cron.daily/logrotate: mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: NO)' error: error running non-shared postrotate script for /var/log/mysql/mysqld.log of '/var/log/mysql/mysqld.log ' I understand that the reason is me having set the root password for MySQL. But my question is how to provide the password to postrotate without disclosing it too much? Other than that the MySQL works well, I use it to host 3 Wordpress websites at my CentOS 8 Linux server (haproxy -> Jetty x 3 -> FastCGI -> php-fpm -> Wordpress -> MySQL) Greetings from Germany Alex

Trying to find gcc 5
by mark 07 Dec '20

07 Dec '20

Hi, folks, It seems I can't run a version of calibre newer than 3.23 without at least one library from gcc-5 (and the calibre attitude seems to be "screw you, 4's ancient, move to another distro"). I've added the scl repo - what devtoolset do I need to install? mark

/dev/mapper/cl-root filesystem corrupted?
by Robert G. (Doc) Savage 07 Dec '20

07 Dec '20

A client's (truly ancient) file server running CentOS 7 suddenly started misbehaving, and I believe the ext4 filesystem on /dev/mapper/cl-root may be corrupted. A reboot fails with a file system check and drops me into maintenance mode. I tried booting from a live C7 DVD and as root running e2fsck. It complains that the superblock could not be read and suggests running "e2fsck -b 8193 <device>". That also fails. Is there a way to more forcefully "encourage" e2fsck to do its job without totally destroying that filesystem? --Doc Savage Fairview Heights, IL

ntpdate past CentOS 7
by Jerry Geis 07 Dec '20

07 Dec '20

So ntpdate is no longer present past CentOS 7. Many times people want "internal" NTP servers - not opening firewalls to allow external pool.ntp.org kind of stuff. ntpdate was "nice" in that I could just run once a day as "ntpdate name" and all good. Is there a similar client for CentOS 8 ? I saw chrony - but does not seem to be a command line command and I would also have to edit a file - Both are not desirable. Just looking for a simple - flexible command like I have been using "ntpdate name" for CentOS 8. Thanks, Jerry

Retrieving files from dd backup
by H 06 Dec '20

06 Dec '20

Running CentOS 7 I have a previously combined backup of a disk with three partitions using dd. I now need to restore one single file from this backup and after perusing the internet, specifically https://unix.stackexchange.com/questions/31669/is-it-possible-to-mount-a-gz…, I have done the following: - installed squashfs-tools - installed kpartx - made a squash image of the dd backup and mounted it - used kpartx to create devices for the three partitions under /dev/mapper/loopNpP - I can now mount the first partition, which is the EFI partition, and access it - the second partition, the boot partition, fails to mount since it has the same UUID as the disk I am using in the computer, and of which it is an earlier dd backup. Since I am not interested in the boot partition - at least not right now - I moved on. - I am, however, interested in the third partition which is LUKS encrypted. Running 'cryptsetup luksOpen /dev/sda3 my_encrypted_volume' I can decrypt it with the password - trying to mount the decrypted version with 'mount /dev/mapper/my_encrypted_volume /media/my_device' results in a failure message 'mount: unknown filesystem type 'LVM2_member' - another website, https://askubuntu.com/questions/766048/mount-unknown-filesystem-type-lvm2-m…, suggests I could run vgdisplay to get the UUID and then rename it using vgrename But, vgdisplay shows only one vg and I am afraid to rename the VG UUID shown by vgdisplay since it might refer to the VG currently in use... Does anyone have any insight or suggestions into the above and how to proceed while being absolutely certain I will not be messing up the running part of the system? Thanks!

Logitech C922 webcam
by H 06 Dec '20

06 Dec '20

Just installed the above USB webcam but it is not recognized by dmesg | grep usb, nor does Zoom recognize it. I was under the understanding it should not require a driver, or? I am running CentOS 7. Thanks.
