openSUSE Tumbleweed to Replace YaST Installer With Agama Before Year End
openSUSE's rolling-release Tumbleweed will switch from the long-standing YaST installer to Agama before the end of the year, and Agama-based images are expected to replace the legacy installer as the main download on get.opensuse.org "within the coming weeks." Both timelines come from an announcement on the project's Factory mailing list, reported by openSUSE News on 9 November 2026.
Test now, while it is still a preview
Two Agama-based images are already downloadable for users who want to try the new installer ahead of the switchover. Tumbleweed's usual quality gates — openQA and staging — continue to determine what reaches the rolling release, and the announcement asks testers to concentrate on installation paths that have historically caused trouble: RAID and LVM configurations, serial-console installs and offline installations. Because Agama is not yet the default, bug reports filed now give the project time to act on differing behaviour before the change becomes routine. An offline installer ISO and a netinstall image are both available, and the traditional image remains on offer for anyone who prefers to wait.
What changes in the installer
Package selection under Agama is organised around patterns rather than individual packages. The announcement describes this as a deliberate choice to simplify installation, though it is a noticeable shift for users accustomed to selecting packages one at a time. The project also acknowledges documentation gaps around profile-based installs and console access, areas it says it is still working to cover.
YaST — an acronym for "Yet another Setup Tool," dating back to April 1995 — is described as entering a state of minimal maintenance. It remains available but is no longer where installation development is focused. The change is not entirely new territory for the project: Leap 16.0 has shipped with Agama since its first release, so the installer has already powered a major openSUSE distribution. A further announcement is planned for when get.opensuse.org is ready to switch.
Relevance for local readers
The change will be relevant to local IT professionals who run Tumbleweed as a workstation or lab platform — particularly those with automated installs or written runbooks built around YaST's workflow, who now have a defined deadline to retest against.
openSUSE Tumbleweed 將於年底前以 Agama 取代 YaST 安裝程式
openSUSE 的 rolling-release 發行版 Tumbleweed 將於年底前由歷史悠久的 YaST 安裝程式轉為採用 Agama，以 Agama 為基礎的映像檔預計「未來數週內」便會取代舊有安裝程式，成為 get.opensuse.org 上的主要下載版本。兩個時間表均出自項目於 Factory 電郵列表發出的公告，openSUSE News 已於 2026 年 11 月 9 日作出報導。
趁仍是預覽版，現在就測試
目前已有兩個以 Agama 為基礎的映像檔可供下載，讓用戶在正式切換前先試用新安裝程式。Tumbleweed 慣常的品質關卡——openQA 及 staging——仍然決定哪些改動會納入這個 rolling release，公告亦呼籲測試者集中測試歷來問題較多的安裝路徑：RAID 及 LVM 配置、經 serial console 進行的安裝，以及離線安裝。由於 Agama 尚未成為預設版本，現時提交的 bug 報告可讓項目在變更成為常態之前，及時處理行為差異的問題。離線安裝程式 ISO 及 netinstall 映像檔均已有提供，傳統映像檔亦繼續保留，供有意再觀望的用戶使用。
安裝程式有何改變
Agama 底下的套件選擇以 pattern 為單位，而非逐個套件挑選。公告形容這是為簡化安裝而作出的刻意選擇，惟對慣於逐一選取套件的用戶而言，變化仍相當明顯。項目亦承認在以 profile 為基礎的安裝及 console 存取方面存在文件缺口，表示相關工作仍在進行中。
YaST——全稱「Yet another Setup Tool」，可追溯至 1995 年 4 月——被描述為進入最低限度維護狀態。它仍會保留，但已不再是安裝開發的焦點所在。此舉對項目而言並非全然陌生的領域：Leap 16.0 自首個版本起便配備 Agama，換言之，此安裝程式已支撐過一個主要的 openSUSE 發行版。項目計劃在 get.opensuse.org 準備好切換之際，再發出另一則公告。
對本地讀者的意義
對於將 Tumbleweed 用作工作站或實驗室平台的本地 IT 專業人士而言，這項變更尤其相關——特別是那些已有自動化安裝、或圍繞 YaST 工作流程編寫 runbook 的人，如今他們已有明確的限期，據以重新測試。
