In this form I set version 10, platform centos 7, arch x86_64 and I has got yum install https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/pgdg-centos10-10-2.noarch.rpm I did this. And on yum update I get: [root@tuchanka1a yum.repos.d]# yum update Загружены модули: fastestmirror Loading mirror speeds from cached hostfile Including mirror: mirror.yandex.ru * base: mirror.yandex.ru Including mirror: mirror.yandex.ru * extras: mirror.yandex.ru Including mirror: mirror.yandex.ru * updates: mirror.yandex.ru base | 3.6 kB 00:00 extras | 3.4 kB 00:00 pgdg10 | 4.1 kB 00:00 updates | 3.4 kB 00:00 zabbix | 2.9 kB 00:00 zabbix-non-supported | 951 B 00:00 pgdg10/7/x86_64/primary_db FAILED http://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/repodata/d1a707282760737faba66b9507aca5d8616de42b883c7692ad09716ed9d5321c-primary.sqlite.bz2: [Errno 14] HTTP Error 404 - Not Found Пробуем другое зеркало.

One of the configured repositories failed (PostgreSQL 10 7 - x86_64), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Run the command with the repository temporarily disabled yum --disablerepo=pgdg10 ... 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable pgdg10 or subscription-manager repos --disable=pgdg10 5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=pgdg10.skip_if_unavailable=true failure: repodata/d1a707282760737faba66b9507aca5d8616de42b883c7692ad09716ed9d5321c-primary.sqlite.bz2 from pgdg10: [Errno 256] No more mirrors to try. http://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/repodata/d1a707282760737faba66b9507aca5d8616de42b883c7692ad09716ed9d5321c-primary.sqlite.bz2: [Errno 14] HTTP Error 404 - Not Found [root@tuchanka1a yum.repos.d]# |
