我試圖在我的 ubuntu 機器上執行這個命令:
yum install libgcc.i686
但是出現這個錯誤在這裡似乎毫無意義:
https://download.postgresql.org/pub/repos/yum/common/redhat/rhel-%24releasever-x86_64/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: pgdg-common. Please verify its path and try again
我嘗試卸載並重新安裝 yum,但沒有成功。怎麼解決這個問題呢?
