# netplan apply命令报错，提示：undefined symbol: g_spawn_check_wait_status

#### 现象描述

执行netplan apply命令时报错。提示如下：

```
(base) root@davinci-mini:
~
/.pip# netplan apply

OSError: /lib/aarch64-linux-gnu/libnetplan.so.0.0: undefined symbol: g_spawn_check_wait_status
```


#### 解决方案

1. 执行ldd -r查看so库链接状态和错误信息。

```
(base) root@davinci-mini:
~
/.pip# ldd -r /lib/aarch64-linux-gnu/libnetplan.so.0.0
linux-vdso.so.1 (0x0000e7ffeafcc000)
libgio-2.0.so.0 => /usr/local/Ascend/mxVision/opensource/lib/libgio-2.0.so.0 (0x0000e7ffead10000)
libgobject-2.0.so.0 => /usr/local/Ascend/mxVision/opensource/lib/libgobject-2.0.so.0 (0x0000e7ffeac90000)
libglib-2.0.so.0 => /usr/local/Ascend/mxVision/opensource/lib/libglib-2.0.so.0 (0x0000e7ffeab10000)
libyaml-0.so.2 => /lib/aarch64-linux-gnu/libyaml-0.so.2 (0x0000e7ffeaae0000)
libuuid.so.1 => /lib/aarch64-linux-gnu/libuuid.so.1 (0x0000e7ffeaac0000)
libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000e7ffea910000)
/lib/ld-linux-aarch64.so.1 (0x0000e7ffeaf93000)
libgmodule-2.0.so.0 => /usr/local/Ascend/mxVision/opensource/lib/libgmodule-2.0.so.0 (0x0000e7ffea8e0000)
libz.so.1 => /lib/aarch64-linux-gnu/libz.so.1 (0x0000e7ffea8b0000)
libselinux.so.1 => /lib/aarch64-linux-gnu/libselinux.so.1 (0x0000e7ffea870000)
libresolv.so.2 => /lib/aarch64-linux-gnu/libresolv.so.2 (0x0000e7ffea840000)
libffi.so.7 => /usr/local/Ascend/mxVision/opensource/lib/libffi.so.7 (0x0000e7ffea810000)
libpthread.so.0 => /lib/aarch64-linux-gnu/libpthread.so.0 (0x0000e7ffea7f0000)
libdl.so.2 => /lib/aarch64-linux-gnu/libdl.so.2 (0x0000e7ffea7d0000)
libpcre2-8.so.0 => /lib/aarch64-linux-gnu/libpcre2-8.so.0 (0x0000e7ffea730000)
undefined symbol: g_spawn_check_wait_status     (/lib/aarch64-linux-gnu/libnetplan.so.0.0)
```


  根据以上信息发现系统库/lib/aarch64-linux-gnu/libnetplan.so.0.0链接到多个mxVision第三方开源库，可以推测是mxVision的第三方开源库与系统版本不兼容导致。

  需要确定mxVision是否为原生ubuntu 22.04下编译构建。

2. 编辑环境变量文件。

```
~
/.bashrc
```


3. 将CANN和mxVision的环境变量注释。

```
# . /usr/local/Ascend/ascend-toolkit/set_env.sh
# . /usr/local/Ascend/mxVision/set_env.sh
```


4. 输入:wq保存退出。
5. 使用新的终端登录并再次执行netplan apply。

```
(base) root@davinci-mini:
~
# netplan apply
(base) root@davinci-mini:
~
#
```


  命令执行成功。

  注意如果是DHCP连接路由器的网口，执行netplan apply后IP可能会改变。

6. 重新执行ldd -r发现libnetplan.so.0.0库已经链接到了正常的系统库。

```
ldd -r /lib/aarch64-linux-gnu/libnetplan.so.0.0
linux-vdso.so.1 (0x0000e7ffd197e000)
libgio-2.0.so.0 => /lib/aarch64-linux-gnu/libgio-2.0.so.0 (0x0000e7ffd16f0000)

libglib-2.0.so.0 => /lib/aarch64-linux-gnu/libglib-2.0.so.0 (0x0000e7ffd1520000)
libyaml-0.so.2 => /lib/aarch64-linux-gnu/libyaml-0.so.2 (0x0000e7ffd14f0000)
libuuid.so.1 => /lib/aarch64-linux-gnu/libuuid.so.1 (0x0000e7ffd14d0000)

libpcre2-8.so.0 => /lib/aarch64-linux-gnu/libpcre2-8.so.0 (0x0000e7ffd1000000)
```


7. 修改“/home/HwHiAiUser/sample/notebooks/start_notebook.sh jupyter”启动脚本如下：

```
. /usr/local/Ascend/ascend-toolkit/set_env.sh
. /usr/local/Ascend/mxVision/set_env.sh
if [ $# -eq 1 ];then
jupyter lab --ip $1 --allow-root --no-browser
else
jupyter lab --ip 192.168.137.100 --allow-root --no-browser
fi
```
