我对我家里的 ubuntu 服务器进行了大量更新（我想我已经一年没有更新任何东西了）。
在此 Transmission 设置文件/var/lib/transmission-daemon/info/settings.json消失后。我再次写入它，Transmission 启动，但过了一会儿它停止并出现此错误：
errr 无法保存简历文件 权限被拒绝
我在以下文件夹和子文件夹授予了 755 权限：
/var/lib/transmission-daemon/info/var/lib/transmission-daemon/download/media/virtual/downloads(“下载目录”)
这是我使用 strace 得到的结果：

现在我从 Web 界面收到此错误：
403: Forbidden
Unauthorized IP Address.
Either disable the IP address whitelist or add your address to it.
If you're editing settings.json, see the 'rpc-whitelist' and 'rpc-whitelist-enabled' entries.
If you're still using ACLs, use a whitelist instead. See the transmission-daemon manpage for details.
文件“settings.json”和“stats.json”已丢失 775，现在为 600。
答案1
我是这样解决的：
1) 卸载 Transmission。全部卸载。每个软件包。
sudo apt-get autoremove transmission-common
2）删除 /var/cache/apt/archives 中的所有 transmission* 软件包
sudo rm /var/cache/apt/archives/transmission*
3）检查你的包管理器是否正常工作
sudo apt-get upgrade && sudo apt-get update
4）重新安装变速器
sudo add-apt-repository ppa:transmissionbt/ppa
sudo apt-get update
sudo apt-get install transmission-cli transmission-common transmission-daemon
