====== Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist ====== Эта ошибка появляется в CentOS 8 из-за перехода репозитория на новый тип выпусков. Или что-то в этом роде. Что бы её побороть, надо переключиться на другой выпуск пакетов, а конкретно Stream, проявляется она вот так: [root@hosting ~]# yum update Failed to set locale, defaulting to C.UTF-8 Repository baseos is listed more than once in the configuration CentOS Linux 8 - AppStream Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist [root@hosting ~]# Для интереса можно зайти в каталог со списками репозиториев и посмотреть что там есть [root@hosting ~]# cd /etc/yum.repos.d/ [root@hosting yum.repos.d]# ls CentOS-Linux-AppStream.repo CentOS-Linux-Debuginfo.repo CentOS-Linux-FastTrack.repo CentOS-Linux-Plus.repo CentOS-Stream-AppStream.repo CentOS-Stream-Debuginfo.repo CentOS-Stream- PowerTools.repo CentOS-Stream-centosplus.repo epel-testing-modular.repo ispsystem-base.repo CentOS-Linux-BaseOS.repo CentOS-Linux-Devel.repo CentOS-Linux-HighAvailability.repo CentOS-Linux-PowerTools.repo CentOS-Stream-Base.repo CentOS-Stream-Extras.repo CentOS-Stream- Sources.repo epel-modular.repo epel-testing.repo ispsystem.repo CentOS-Linux-ContinuousRelease.repo CentOS-Linux-Extras.repo CentOS-Linux-Media.repo CentOS-Linux-Sources.repo CentOS-Stream-BaseOS.repo CentOS-Stream-Media.repo CentOS-Stream- Vault.repo epel-playground.repo epel.repo В моём случае там слишко много всего, видно что там есть подключенные репо и Linux и Stream. Попробуем установить пакет centos-release-stream-8.1, его можно скачать откуда угодно, но я использовал эту ссылку. [root@hosting yum.repos.d]# rpm -i http://mirror.centos.org/centos/8/stream/extras/x86_64/os/Packages/centos-release-stream-8.1-1.1911.0.7.el8.x86_64.rpm package centos-release-stream-8.1-1.1911.0.7.el8.x86_64 is already installed Пакет на самом деле стоит, но всё равно ничего не работает. На всякий случай всё удаляем [root@hosting yum.repos.d]# rpm -qa | grep centos-release-stream [root@hosting yum.repos.d]# rpm -e centos-release-stream-8.1-1.1911.0.7.el8.x86_64 И устанавливаем заново [root@hosting yum.repos.d]# rpm -ivh http://mirror.centos.org/centos/8-stream/extras/x86_64/os/Packages/centos-release-stream-8.1-1.1911.0.7.el8.x86_64.rpm Retrieving http://mirror.centos.org/centos/8-stream/extras/x86_64/os/Packages/centos-release-stream-8.1-1.1911.0.7.el8.x86_64.rpm Verifying... ################################# [100%] Preparing... ################################# [100%] Updating / installing... 1:centos-release-stream-8.1-1.1911.################################# [100%] Пакет поставлен, теперь переключаемся между релизами.

Что бы её полечить надо отключить предыдущий репозиторий AppStream [root@hosting yum.repos.d]# vi CentOS-Linux-AppStream.repo Ищем там enabled=1 И меняем на enabled=0 Сохраняем, выходим, запускаем ещё раз [root@hosting yum.repos.d]# dnf swap centos-{linux,stream}-repos -y Failed to set locale, defaulting to C.UTF-8 Repository baseos is listed more than once in the configuration CentOS Linux 8 - BaseOS Error: Failed to download metadata for repo 'baseos': Cannot prepare internal mirrorlist: No URLs in mirrorlist Теперь отключаем так же другой репозиторий [root@hosting yum.repos.d]# vi CentOS-Linux-BaseOS.repo Запускаем ещё раз [root@hosting yum.repos.d]# dnf swap centos-{linux,stream}-repos -y Failed to set locale, defaulting to C.UTF-8 Repository baseos is listed more than once in the configuration CentOS Linux 8 - Extras CentOS Linux 8 - PowerTools Error: Failed to download metadata for repo 'powertools': Cannot prepare internal mirrorlist: No URLs in mirrorlist И ещё раз выключаем третий репо [root@hosting yum.repos.d]# vi CentOS-Linux-PowerTools.repo Обычно этого достаточно, дальше запускаем и оно всё отрабатывает [root@hosting yum.repos.d]# dnf swap centos-{linux,stream}-repos -y Failed to set locale, defaulting to C.UTF-8 Repository baseos is listed more than once in the configuration CentOS-Stream - AppStream CentOS-Stream - Base CentOS-Stream - Extras Extra Packages for Enterprise Linux 8 - x86_64 Extra Packages for Enterprise Linux Modular 8 - x86_64 ispsystem-5.279 ispsystem-base Dependencies resolved. =========================================================================================================== Package Architecture Version Repository Size =========================================================================================================== Installing: centos-stream-release noarch 8.6-1.el8 Stream-BaseOS 22 k replacing centos-linux-release.noarch 8.5-1.2111.el8 replacing centos-release-stream.x86_64 8.1-1.1911.0.7.el8 centos-stream-repos noarch 8-4.el8 Stream-BaseOS 20 k Upgrading: centos-gpg-keys noarch 1:8-4.el8 Stream-BaseOS 12 k Removing: centos-linux-repos noarch 8-3.el8 @baseos 26 k Transaction Summary =========================================================================================================== Install 2 Packages Upgrade 1 Package Remove 1 Package Total download size: 54 k Downloading Packages: (1/3): centos-gpg-keys-8-4.el8.noarch.rpm (2/3): centos-stream-release-8.6-1.el8.noarch.rpm (3/3): centos-stream-repos-8-4.el8.noarch.rpm ----------------------------------------------------------------------------------------------------------- Total 39 kB/s | 54 kB 00:01 Running transaction check Transaction check succeeded.
