无法解析‘usr/share/mime/packages/gnuradio.xml’

安装时出现此错误gnuradio。我还遇到了以下问题：

usr/share/mime/packages/gnuradio.xml:1: parser error : Start tag expected, '<' not found.

我应该担心吗？其他一切都顺利完成，没有错误。

答案1

  1. 删除/usr/share/mime/packages/gnuradio.xml。

  2. 符号链接gnuradio-grc.xml到gnuradio.xml：

    sudo ln -s gnuradio-grc.xml gnuradio.xml

答案2

错误信息

patrick@Aspire1:~$ ls -al /usr/share/gnuradio/grc/freedesktop/gnuradio-grc.xml

错误信息调出文件，行号（':1:'）然后在下一行显示错误输入（实际上是文件的全部内容（即唯一行））并用'^'指出出错的地方。

分析
  • Linux 正在尝试使用 gqrx 安装包提供的 XML 格式数据，用与 gnuradio 关联的对象的新条目来更新 mime 类型数据库
  • 出于只有他们自己知道的原因，软件包维护者在 /usr/share/gnuradio/grc/freedesktop/gnuradio 中提供了数据-grc.xml 而 mime 更新实用程序正在寻找 /usr/share/gnuradio/grc/freedesktop/gnuradio.xml (NB NO '-grc')，而是通过将 *-grc.xml 文件名放在 *.xml 文件中并期望 update-mime-database 能够弄清楚来指向 XML。
  • update-mime-database 抛出错误消息，终止 apt install 进程

可以通过手动更新 mime 数据库来复制，如下所示：

sudo update-mime-database -V /usr/share/mime/

解决
  1. gnuradio.xml 的内容不好所以删除它
    2. sudo rm /usr/share/mime/packages/gnuradio.xml
  2. gnuradio-grc.xml 的内容是所需要的，因此链接它
    4。sudo ln -s /usr/share/gnuradio/grc/freedesktop/gnuradio-grc.xml /usr/share/gnuradio/grc/freedesktop/gnuradio.xml
  3. 测试sudo update-mime-database -V /usr/share/mime/

可能需要手动指示 apt 和/或 dpkg 从这里继续。无论如何，这不太可能造成任何损害。

sudo apt-get -f install

sudo dpkg --configure -a

答案3

sudo nano /usr/share/mime/packages/gnuradio.xml

转到第一行，确保它以<

sudo update-mime-database -V /usr/share/mime/

这将更新 mime 数据库。
