我将 Python 2.7.15+ 符号python链接到python3. 当我尝试将 Ubuntu 升级到 19.04 时

sudo do-release-upgrade

它返回以下错误：

Traceback (most recent call last):
  File "/tmp/ubuntu-release-upgrader-k7w2kx7r/disco", line 8, in <module>
    sys.exit(main())
  File "/usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeMain.py", line 238, in main
    if app.run():

    return self.fullUpgrade()

通常，我应该编写一个 FileType.xml 并使用

xdg-mime install FileType.xml

然后使用

xdg-mime default xxx.desktop file-type

设置默认应用程序和

xdg-icon-resource install xxx

设置默认图标。最后，删除FileType.xml。
老实说，我永远记不起 FileType.xml 的格式和“xdg-icon-resource”的参数。当我想安装新的文件类型时，这对我来说是一种折磨。
那么，有 xdg-mime 的 GUI 工具吗？
