So, it looks like you are using CentOS Stream, and still have the regular CentOS repositories enabled. Which, last time I installed CentOS Stream, was the default. My opinion: I think if you install CentOS Stream, you should have only the CentOS Stream repo's enabled by default. (^^ This is a note to the CentOS Stream developers) Having the other repositories enabled just messes things up, like this example. Anyway, for my stream machines, I do the following after an install. dnf config-manager --disable AppStream dnf config-manager --disable BaseOS dnf config-manager --disable extras dnf config-manager --disable PowerTools dnf config-manager --enable Stream-PowerTools On Fri, Apr 17, 2020 at 7:21 AM lejeczek via CentOS-devel <centos-devel at centos.org> wrote: > > hi everyone. > > dnf updates collide: > > $ dnf update corosynclib > Last metadata expiration check: 0:19:02 ago on Fri 17 Apr > 2020 14:57:48 BST. > Error: > Problem: problem with installed package > corosync-3.0.2-3.el8_1.1.x86_64 > - package corosync-3.0.2-3.el8_1.1.x86_64 requires > corosynclib(x86-64) = 3.0.2-3.el8_1.1, but none of the > providers can be installed > - cannot install both corosynclib-3.0.3-2.el8.x86_64 and > corosynclib-3.0.2-3.el8_1.1.x86_64 > - cannot install the best update candidate for package > corosynclib-3.0.2-3.el8_1.1.x86_64 > (try to add '--allowerasing' to command line to replace > conflicting packages or '--skip-broken' to skip > uninstallable packages or '--nobest' to use not only best > candidate packages) > > $ dnf list corosynclib --showduplicates > Last metadata expiration check: 0:18:45 ago on Fri 17 Apr > 2020 14:57:48 BST. > Installed Packages > corosynclib.x86_64 > 3.0.2-3.el8_1.1 > @AppStream > Available Packages > corosynclib.i686 > 3.0.2-3.el8 > AppStream > corosynclib.x86_64 > 3.0.2-3.el8 > AppStream > corosynclib.i686 > 3.0.2-3.el8_1.1 > AppStream > corosynclib.i686 > 3.0.2-3.el8_1.1 > HighAvailability > corosynclib.x86_64 > 3.0.2-3.el8_1.1 > AppStream > corosynclib.i686 > 3.0.3-2.el8 > Stream-AppStream > corosynclib.x86_64 > 3.0.3-2.el8 > Stream-AppStream > > It cannot be that those(some of?) repos exclude each other, > right? > > many thanks, L. > _______________________________________________ > CentOS-devel mailing list > CentOS-devel at centos.org > https://lists.centos.org/mailman/listinfo/centos-devel
