我一直在使用cronopete和timeshift在 Pop!_OS 上进行备份。cronopete仅/home针对timeshift整个系统。
我放入了一个新的 m.2 NVMe 驱动器，希望可以将timeshift备份恢复到空白驱动器，但事实并非如此。
我最终必须将所有内容重新安装到 Pop!_OS 的全新安装中，然后将备份/home从中复制过来cronopete。
看起来它基本上起作用了，但现在我尝试这样做sudo apt install python3-virtualenv却出现了错误：
sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the 'nosuid' option set or an NFS file system without root privileges?
我遇到了以下问题，但它仍然无法帮助我解决问题。我不太清楚我需要做什么。

Q) Sudo compiles and installs OK but when I try to run it I get:
effective uid is not 0, is /usr/local/bin/sudo on a file system with the
'nosuid' option set or an NFS file system without root privileges?
A) The owner and permissions on the sudo binary appear to be OK but when
sudo ran, the setuid bit did not have an effect. There are two common
causes for this. The first is that the file system the sudo binary
is located on is mounted with the 'nosuid' mount option, which disables
setuid binaries. The output of the "mount" command should tell you if
the file system is mounted with the 'nosuid' option. The other possible
cause is that sudo is installed on an NFS-mounted file system that is
exported without root privileges. By default, NFS file systems are
exported with uid 0 mapped to a non-privileged uid (usually -2). You
should be able to determine whether sudo is located on an NFS-mounted
filesystem by running "df `which sudo`".
它建议运行的两个命令的输出如下：

关于如何解决这个问题有什么建议吗？
答案1
好的，这似乎已经解决了问题。主要基于此处找到的答案：
space启动 Pop!_OS 时按住- 选择
Recovery，弹出操作系统安装程序 SUPER + T打开终端sudo -i切换到根目录mount -o remount,rw /mount --allchown root:root /usr/bin/sudochmod 4755 /usr/bin/sudo- 重启Pop!_OS并正常登录
现在我可以运行sudo诸如此类的命令，sudo apt install python3-virtualenv到目前为止没有任何问题。
答案2
首先，通过以下方式打开 root：
$ sudo -s
然后 ：
# chmod u+s /usr/bin/sudo
完毕 ！
