在帶有肉桂桌面的debian 10 buster中設置預設pdf閱讀器

我查看了有關將預設 pdf 閱讀器設置為 evince 的問題。對於我在 cinnamon 桌面上安裝 debian 10.3 似乎沒有任何幫助。我四處尋找，可以找到這個：

$ cat /usr/share/applications/x-cinnamon-mimeapps.list | grep pdf
application/pdf=evince.desktop;
application/x-ext-pdf=evince.deskto;

還有這個：

$ cat .config/mimeapps.list 

[Default Applications]
x-scheme-handler/tg=telegramdesktop.desktop
application/pdf=evince.desktop
application/x-ext-pdf=evince.desktop

和所有其他可能的地方：

$ grep -rnw /usr/share/applications/ -e pdf

這似乎表明當你點兩下一個 pdf 文件時，它應該已經用 evince 啟動了，但是它用 libreoffice 啟動了。任何想法如何解決這一問題？

如果您點兩下pdf意味著從文件管理器中打開它，那麼您使用的是哪個管理器？它們可以有自己的 mime 類型處理，例如，在 Nautilus 中，您可以通過使用右鍵點擊文件、打開屬性、選擇使用選項卡打開並將應用程序設置為預設值來更改它。
