This is most likely because you’re getting different mirrors for baseos and appstream. Your appstream metadata is up-to-date, while your baseos metadata is out of date. You can try running `dnf --refresh update` and see if that works. ---

My nearest mirror does (now) have version 3.12.13-2.el10\_2.1 of both packages. > [@jdieter](#): > > you’re getting different mirrors for baseos and appstream If the mirror servers are different and metadata does come from servers, then the mirror that did not yet have the `el10_2.1` would still supply the metadata that does not know about the `el10_2.1` packages? Do the ```auto dnf repoinfo baseos dnf repoinfo appstream ``` list different host in ‘Repo-baseurl’? * * * I do usually: ```plaintext dnf clean all ``` It might make dnf select different mirrors. * * * To show the package versions that dnf sees now: ```bash dnf list --showduplicates python3 python-unversioned-command ``` ---

If we browse `https://rockylinux.netforce.hosting/rocky/` (that you do now use), then we see that latest timestamps there seem to be **2026-06-05** (more than a month old). The other mirror, `https://distrohub.kyiv.ua/rockylinux/` has timestamps up to **2026-07-16** (yesterday). The rockylinux.netforce.hosting is not a good mirror, because it is not in sync with Rocky. * * * You do not see issues in “dnf update”, because it now consistently sees only old packages. You do have the issue that you cannot update your Rocky (because dnf chose a stale mirror). ---

1. Which one mirror should I replace it with? 2. Why did the installer choose mirrors that don’t update? 3. Which mirrors are preferable to use ? ---

For 2: The installer does not know better. The assumption is that all mirrors are up to date. If a mirror is not syncing, then its maintainer and/or Rocky’s mirror service maintainers should be contacted in order to fix the sync or to remove the server from the list of mirrors. ---
