我对在Linux/Ubuntu上工作相当陌生,我发现Application需要从root特权开始,然后删除根
我想知道上述声明是什么意思?
同样,当我执行应用程序二进制时,我可以看到控制台上正在打印以下语句
Warning: group= user1 not found in /etc/group file
Warning: UID 1041 not known in the system. Test may fail.
drop root to uid [1041] complete
有人能帮我理解一下吗?谢谢
任何启用了linux的flutter应用程序的linux版本都会导致以下错误:
flutter run -d linux
Launching lib/main.dart on Linux in debug mode...
/snap/flutter/current/usr/bin/ld: warning: /usr/lib64/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../lib64/crt1.o: unsupported GNU_PROPERTY_TYPE (5) type: 0xc0008002

我已经在我的Ubuntu系统上安装了GitHub self-hosted runner。当我试图将它配置为服务时,会出现以下错误。
$ sudo ./svc.sh start
Failed to start actions.runner._services.Linux-Host01.service: Unit actions.runner._services.Linux-Host01.service is not loaded properly: Exec format error.

在scp-ing向openSUSE 12.2 Linux提供了shell修补的bash二进制文件并用它替换登录外壳后,没有任何用户可以通过ssh或控制台登录。事实证明,尽管使用了-p开关,可执行位还是在传输过程中丢失了。
我试图通过在Linux主机上挂载文件系统并执行chmod +x /mnt/usr/local/bin/bash来修复这个问题,但是情况并没有改善。重新启动来宾VM会有帮助吗?
这就是我在控制台上看到的:
xxx login: root
Password:
Last login: xxx
Have a lot of fun...

我有KMtronics USB继电器,我想用我的Android设备来控制它。是否可以运行以下Linux命令:
#!/bin/sh
# sends on signal to the USB relay
echo -e '\xff\x01\x01' > /dev/ttyUSB0
我尝试用一些Shell Executor应用程序执行相同的命令,但总是得到Permission Denied或Unable to create file/folder。甚至我也尝试过在有根的设备上运行它。
当我跑的时候
mkdir ../../bin/Release_Linux/Resources
我犯了个错误
$ mkdir ../../bin/Release_Linux/Resources
mkdir: cannot create directory ‘../../bin/Release_Linux/Resources’: No such file or directory
或者只是
mkdir Release_Linux/Resources
mkdir: cannot create directory ‘Release_Linux/Resources’: No such file or d
我尝试在ubuntu11.04中安装java,我下载了"jdk-1_5__22-linux-i586.bin“,为此我使用了教程和
# sudo mv jdk-1_5_0_22-linux-i586.bin /usr/lib/jvm
# cd /usr/lib/jvm
# chmod +x jdk-1_5_0_22-linux-i586.bin
# ./jdk-1_5_0_22-linux-i586.bin
当我执行命令# ./jdk-1_5_0_22-linux-i586.bin时,我得到了以下错误消息

当尝试执行此命令时:

我一直在和hidraw.h打交道,想看看我的USB能做些什么,但是当我试图打开/dev/hidraw0时,它写着Unable to open device: Permission denied,我知道我可以做一些类似于system("sudo open /dev/hidraw0");的事情,但是它当然不会有同样的效果。而且我在Kali Linux。这是我的密码:

#include <linux/types.h>
#include <linux/input.h>

我正在尝试交叉编译arm设备的gst-ti-plugin,但是当我这样做时,make install libtool会返回错误:
../libtool: line 1085: arm-none-linux-gnueabi-ranlib: command not found
这里的问题是这个工具在PATH上是可用的,当我从控制台尝试它时,它工作得很好。
有什么不对的?我使用CodeSourcery工具链。
