1. USB pnp: Thunar can not mount USB sticks automatically. You check the pnp setting first, let the pnp on. Then install thunar-volman package logout and login one time, then USB pnp can be used.

dropbox-lnx.x86_64-210.4.4854.tar.gz ... failed solved

 dropbox-lnx.x86_64-210.4.4854.tar.gz ... fail

I solved it by a stupid method. I always used paru for my first AUR helper. But I always installed yay for my second choice. So I used the command "paru -Rns dropbox" to uninstall the older version dropbox, then used yay to install the new version. It worked.

這個異常是因為金鑰問題需要更新。反正 arch論壇上大大們的解法，我看不懂，也不會。所以我就用比較暴力的方法解決這個問題，一開始我也是抱著試試看的想法，結果是我想要的，這樣就可以了！

方法如下：

1.執行 paru -Rns dropbox 指令，把所有系統裡的 dropbox相關檔案清光。

2.執行 yay -S dropbox 指令，重裝 dropbox。

3.
