Problem:
You are trying to install an OpenWRT package using e.g.
opkg install luci-app-openvpn
but you see an error message like
Unknown package 'luci-app-openvpn'. Collected errors: * opkg_install_cmd: Cannot install package luci-app-openvpn.
Solution:
There are two different reasons why this error can occur:
- You forgot to run
opkg update
Note that you need to run
opkg update
after each reboot since the package lists are only stored in the RAM - The package actually doesn’t exist. Check
opkg list
for a list of packages that can be installed for your OpenWRT version and architecture. In very rare cases you might need to build a package from source if it isn’t available, or you might need to upgrade your OpenWRT version if that’s possible for your router.
