I believe that you experience of consequence of modular filtering (not a bug). Please see https://github.com/rpm-software-management/dnf/blob/master/doc/modularity.rst. When module postgresql is enabled or default, all packages that has the same name with modular packages are excluded from all repositories. To disable modular filtering for certain repository, just add "module_hotfixes=true" into corresponding .repo file in /etc/yum.repos.d/. Hope that it helps. Interesting! Thank you for the pointer. It works as expected. I'm not sure what package name they have in common though, as wall packages in PGDG repo avec suffixed with the major version, eg: postgresql11, postgresql11-server, etc. But anyway. I supposed the best approach would be to add modules in the pgdg repository itself. It sounds the perfect fit to provide all supported PostgreSQL major version from one repo (PGDG provide one repo per version today). However, what happen when two repo provide same module name? Thanks again anyway! One additional note though. I suppose this modular filtering should appears somewhere as a warning or at least as a debug message. Today, this is just black hole pretty hard to detect for newcomers in RHEL8 and/or modules and streams :/ |
yum/dnf refuse to find/install many packages from PGDG repository on RHEL8 After installing the PGDG repository from yum.postgresql.org on RHEL8, I expect the following command to install PostgreSQL 11 and its dependencies: [root@localhost ~]# yum install postgresql11 postgresql11-server \ postgresql11-contrib Updating Subscription Management repositories. Last metadata expiration check: 0:00:49 ago on Fri May 17 16:33:48 2019. No match for argument: postgresql11 No match for argument: postgresql11-server No match for argument: postgresql11-contrib Error: Unable to find a match The package exists from the repository, eg: [root@localhost ~]# yum --quiet repoquery --repo pgdg11 postgresql11-server* postgresql11-server-0:11.2-2PGDG.rhel8.x86_64 postgresql11-server-0:11.3-1PGDG.rhel8.x86_64 Even searching for the package doesn't work: [root@localhost ~]# yum search postgresql11-server Updating Subscription Management repositories. Last metadata expiration check: 0:23:08 ago on Fri May 17 00:23:20 2019. No matches found. A workaround to this issue is currently to disable the "postgresql" module from appstream: [root@localhost ~]# yum -qy module enable postgresql [root@localhost ~]# yum -q info postgresql11-server|grep ^Name Error: No matching Packages to list [root@localhost ~]# yum -qy module disable postgresql [root@localhost ~]# yum -q info postgresql11-server|grep ^Name Name : postgresql11-server The only dependency who match a package in appsteam is on "libpq.so.5". This lib provided by package "postgresql11-libs" from the PGDG repo. Behavior is quite surprising. I suppose the package manager should provide a better error message /advice if there is some conflicts or dependency issues or if it is not able to make a choice between two packages. Moreover, is it something to be fixed on "postgresql" module side or in PGDG repo side? How? Thanks,
