请问版本 77.0.3865.129（FydeOS 非商业授权版） （64 位）如何在线升级，可以手动升级吗
FydeOS for PC 发行版支持联网 OTA 升级，在「关于 FydeOS」中检查更新即可。如果是其它 FydeOS 版本（包括但不限于 FydeOS for You），建议手动升级到最新。
我的是FydeOS for PC， 硬盘安装的，检查更新永远是最新版本，不能OTA升级
我司运维的 FydeOS OTA 升级服务器现在运转正常，目前正在响应各种升级需求。
要调查你的安装为何不能 OTA 升级，需要提供相关的日志文件：/var/log/update_engine.log

磁盘空间不够了。删点东西吧，至少留个 2G
可否提供一下 lsblk 命令的输出？另外请问你是如何将 FydeOS 安装到硬盘的？
制作fydeosU盘启动盘，然后安装到整个磁盘，此版本是从低版本OTA升级而来，现在不能再更新新版本了
