Hello, I have installed CentOS from a CentOS-5.6-x86_64-bin-DVD-1of2.iso and then installed PGDG because I want to have PostgreSQL 8.4.7: # rpm -Uvh http://www.pgrpms.org/8.4/redhat/rhel-5-x86_64/pgdg-centos-8.4-2.noarch.rpm # cat /etc/yum.repos.d/pgdg-84-centos.repo [pgdg84] name=PostgreSQL 8.4 $releasever - $basearch baseurl=http://yum.pgrpms.org/8.4/redhat/rhel-$releasever-$basearch enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG [pgdg84-source] name=PostgreSQL 8.4 $releasever - $basearch - Source failovermethod=priority baseurl=http://yum.pgrpms.org/srpms/8.4/redhat/rhel-$releasever-$basearch enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG Then I'm trying to install the PGDG-packaged PostgreSQL, but keep getting the error message I don't understand: # sudo yum install postgresql-server postgresql-devel postgresql-docs postgresql Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.atrpms.net * extras: mirror.atrpms.net * updates: mirror.atrpms.net Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package postgresql.x86_64 0:8.4.7-1PGDG.rhel5 set to be updated --> Processing Dependency: postgresql-libs = 8.4.7-1PGDG.rhel5 for package: postgresql --> Processing Dependency: libpq.so.5()(64bit) for package: postgresql ---> Package postgresql-devel.i386 0:8.1.23-1.el5_6.1 set to be updated --> Processing Dependency: postgresql = 8.1.23-1.el5_6.1 for package: postgresql-devel ---> Package postgresql-devel.x86_64 0:8.4.7-1PGDG.rhel5 set to be updated ---> Package postgresql-docs.x86_64 0:8.4.7-1PGDG.rhel5 set to be updated ---> Package postgresql-server.x86_64 0:8.4.7-1PGDG.rhel5 set to be updated --> Running transaction check ---> Package postgresql-devel.i386 0:8.1.23-1.el5_6.1 set to be updated --> Processing Dependency: postgresql = 8.1.23-1.el5_6.1 for package: postgresql-devel --> Processing Dependency: libpq.so.4()(64bit) for package: php53-pgsql --> Processing Dependency: libpq.so.4()(64bit) for package: apr-util --> Processing Dependency: libpq.so.4()(64bit) for package: perl-DBD-Pg ---> Package postgresql-libs.x86_64 0:8.4.7-1PGDG.rhel5 set to be updated --> Running transaction check ---> Package compat-postgresql-libs.x86_64 0:4-1PGDG.rhel5 set to be updated ---> Package postgresql-devel.i386 0:8.1.23-1.el5_6.1 set to be updated --> Processing Dependency: postgresql = 8.1.23-1.el5_6.1 for package: postgresql-devel --> Finished Dependency Resolution postgresql-devel-8.1.23-1.el5_6.1.i386 from updates has depsolving problems --> Missing Dependency: postgresql = 8.1.23-1.el5_6.1 is needed by package postgresql-devel-8.1.23-1.el5_6.1.i386 (updates) Error: Missing Dependency: postgresql = 8.1.23-1.el5_6.1 is needed by package postgresql-devel-8.1.23-1.el5_6.1.i386 (updates) You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest The program package-cleanup is found in the yum-utils package. I've tried to find a combination of packages which would work, but haven't succeeded. Here are the currently installed packages: # rpm -qa|grep -i "\\<pg" pgdg-centos-8.4-2 php53-pgsql-5.3.3-1.el5_6.1 perl-DBD-Pg-1.49-2.el5_3.1 # rpm -qa|grep -i post postgresql-libs-8.1.23-1.el5_6.1 postgresql-libs-8.1.23-1.el5_6.1 Does anybody know the magic command for me? (besides "man yum" :-) Thank you Alex -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
