debian9.2 ,gnome,新安装的系统重启后新立德报错

nRelease: The key(s) in the keyring /etc/apt/trusted.gpg are ignored as the file is not readable by user ‘_apt’ executing apt-key.

尝试临时将 /etc/apt/trusted.gpg 移走。

多谢指点,我直接把这个文件删了,就没有这个报错了,但只要apt update,就会有一个文件下载失败,然后继续这种报错,我换了好几个源,都是这样,就是固定的那个文件下载失败或者被忽略

把原始信息贴上来,有信息才能知道究竟哪里出了问题。

抱歉,我正在升testing,不能复现错误拷提示信息给你了,然而每次update就是固定的我主贴贴的那两句错误提示,删了/etc/apt/trusted.gpg以后,只要再次update,就仍然是这两句提示,而且这个文件会再次生成。
ps:我升testing的时候没有杀xorg进程,现在直接在gnome的终端里面upgrade,不知滚完会不会挂。。。。现在瑟瑟发抖

有任何错误信息都应该截图或者复制原始信息过来,要不然真的没法分析问题在哪里。
