10   Trouble Shooting  
10.1   I get kernel error when install new package, how to fix? 
In some cases, when installing a package with opkg, it will generate a kernel error such as below 
due to a mismatch I the kernel ID: 
 
root@dragino-16c538:~# opkg install kmod-dragino2-si3217x_3.10.49+0.2-1_ar71xx.ipk 
Installing kmod-dragino2-si3217x (3.10.49+0.2-1) to root… 
Collected errors: 
* satisfy_dependencies_for: Cannot satisfy the following dependencies for kmod-dragino2-
si3217x: 
*  kernel (= 3.10.49-1-4917516478a753314254643facdf360a) *  
 * opkg_install_cmd: Cannot install package kmod-dragino2-si3217x.  
 
In this case, you can use the –force-depends option to install such package as long as the actual 
kernel version is the same.  
Opkg install kmod-dragino2-si3217x_3.10.49+0.2-1_ar71xx.ipk –force-depends
