To upgrade a group of packages, run opkg upgrade packagename1 packagename2.Ī list of upgradeable packages can be obtained with the opkg list-upgradable command. You can safely delete the contents of this folder anytime to free up some RAM (its content is also lost on reboot), don't forget to run opkg update again before you install a new package. OPKG needs the content of this folder in order to install or upgrade packages or to print info about them. As of LEDE 17.01, after the opkg upgrade, this folder occupies about 450 KiB of space. This simply retrieves a file like this one: example, for your installation and stores it on your RAM partition under /tmp/opkg-lists. When on trunk/snapshot, kernel and kmod packages are flagged as hold, the opkg upgrade command won't attempt to update them. In this case, you will get the error message “Cannot satisfy the following dependencies for…”.įor such usage of OpenWrt firmware, it's warmly recommended to use the Image Builder to make a flashable image containing all packages you need. If you are using a snapshot / trunk / bleeding edge version, installing packages may fail if the package in the repository is for a newer kernel version than the kernel version you have.

To ignore dependency errors, pass the -force-depends flag. Missing dependencies with third-party packages are probably available from the source of the package. The package manager opkg attempts to resolve dependencies with packages in the repositories - if this fails, it will report an error and abort the installation of that package. Opkg is sometimes called Entware, as it is used also in the Entware repository for embedded devices (a fork of OpenWrt community packages repository). Opkg is a full package manager for the root file system, including kernel modules and drivers, while ipkg is just a way to add software to a separate directory (e.g. Opkg is a fork of ipkg, the package manager used in NSLU2's Optware, which is designed to add software to stock firmware of embedded devices.

The opkg utility is the lightweight package manager used for this job. Like most Linux distributions (or mobile device operating systems like say Android or iOS), the functionality of the system can be upgraded rather significantly by downloading and installing pre-made packages from package repositories (local or on the Internet).
