We highly recommend glancing over this tutorial as it will likely help resolving any problems you may have regarding installing new applications.
opkg is the packge installer and manager used by OpenWRT. Its purpose is akin to the windows installer wizard, the apt-get installer on Ubuntu. Opkg comes connected to a few repositories including our own so that packages can be easily downloaded and installed to your Omega.
To see which repositories are connected enter the following into the command line.
We will look at a few of the more important commands and options when using opkg. Firstly, lets look at opkg update. Make sure you run this command before trying to install any packages.
This will update opkg list of available packages. If you try to install a package without running opkg update first, opkg may not be able to find the package you are looking for.
Next to install a particular package, use the following command.
opkg install <packagename>
This will search through the list of available packages. If you would like, you can point the opkg installer to install from a particular repository or from a local directory.
opkg install <urltopackage>
opkg install <pathtopackage>
Sometimes it is also useful to see which packages we have already installed.
You can also upgrade a package or a group of packages using the following command.
opkg upgrade <packages>
As per the OpenWRT wiki, this is not recommended. For two main reasons:
1) It is far more inefficient at allocating memory than the default installation process.
2)If you are upgrading a kernel package and there are compatibility issues, your device may break. Therefore, Do Not Upgrade Kernel Packages.
Instead of upgrading, it is recommended to reflash OpenWRT with the newer firmware image.
Lastly, to remove a package, you can use the following command:
opkg remove <packages>
