Page or section

Get started → SELF-HOSTED TIMESCALEDB → Install self-hosted TimescaleDB

What's wrong or unclear

Step 1
has incorrect command, it should have "dnf makecache" like described in bug #461

"Step 2" Install the latest PostgreSQL packages
sudo dnf install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-9-x86_64/pgdg-redhat-repo-latest.noarch.rpm

What you expected

Above URL is fixed see inside the link "EL-9" which if fine for Rocky Linux 9, but on Rocky Linux 10 should be "EL-10", so:
sudo dnf install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-10-x86_64/pgdg-redhat-repo-latest.noarch.rpm

Suggestion:

• add section for Rocky Linux 9 and Rocky Linux 10
• or better add variable (check the Red Hat documentation).

---

NOTE: Probably issue appeared when documentation was initially copied from Red Hat doc, but in case of Rocky Linux only version 9 was supported, so instead of variable (like in Red Hat doc), at Rocky Linux is fixed version number.
