我現在使用的是 Fedora 27。今天我嘗試透過運行來安裝 openvpn
dnf install openvpn easy-rsa
這給出了以下輸出：
Failed to synchronize cache for repo 'pgdg95', disabling.
Last metadata expiration check: 1:33:10 ago on Tue 29 May 2018 01:37:39 PM IST.
Package openvpn-2.4.6-1.fc27.i686 is already installed, skipping.
Package easy-rsa-3.0.3-1.fc27.noarch is already installed, skipping.
Dependencies resolved.
Nothing to do.
Complete!
當我運行這些命令時
dnf install network-manager-openvpn openvpn
dnf install vlc
dnf install kdevelop
它們會傳回以下輸出：
Failed to synchronize cache for repo 'pgdg95', disabling.
Last metadata expiration check: 1:33:10 ago on Tue 29 May 2018 01:37:39 PM IST.

我無法在終端機中安裝新的軟體包。當 dnfdragora 對話方塊更新軟體套件時，會帶來一定程度的喘息。
PS：我嘗試過dnf clean，但沒有成功。我沒有安裝 vlc 和 kdevelop。
答案1
嘗試：sudo dnf clean all && sudo dnf upgrade
