前幾日給我的安卓手機安裝了Termux，開始了我的暑假搞機之旅，好不容易給它裝上了ArchLinux，在我使用pacman更新時卻報了這樣的錯誤：
error: libxinerama: signature from "Arch Linux ARM Build System <builder@archlinuxarm.org>" is unknown trust
:: File /var/cache/pacman/pkg/libxinerama-1.1.4-1-aarch64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).

看起來大概意思是軟件的簽名有問題。
Excuse me？
你系統(tǒng)自己設定的軟件來源你現(xiàn)在告訴我你自己不信任他？？
好吧，生活還是要繼續(xù)的：百度，google，blahblah，我這么解決了這個問題：
pacman-key --init
pacman-key --populate
這上邊兩條命令，一條條輸入進去執(zhí)行一下，然后就可以使用pacman了
嘗試安裝screenfetch，成功了！
順便曬一曬手機里的arch：
哈哈哈哈
