我试图在我的 ubuntu 机器上执行这个命令:
yum install libgcc.i686
但是出现这个错误,这似乎毫无意义:
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
我尝试卸载并重新安装 yum,但没有效果。如何解决?
