Hello, I don't have enough space to install one package I need so I'm trying to remove some packages I don't need (such as pppoe, IPv6 etc) but I get this when I try to do so:
Collected errors:
pkg_get_installed_files: Failed to open //usr/lib/opkg/info/kmod-pppoe.list: No such file or directory.
pkg_get_installed_files: Failed to open //usr/lib/opkg/info/kmod-pppox.list: No such file or directory.
pkg_get_installed_files: Failed to open //usr/lib/opkg/info/ppp-mod-pppoe.list: No such file or directory.
pkg_get_installed_files: Failed to open //usr/lib/opkg/info/ppp-mod-pppoe.list: No such file or directory.
Then there's no point in trying, deleting might actually consume space instead
You can build your own image, if you want to omit some packages, or if your device uses the ath71xx target, swap to ath79 (images should already be available). The swap itself will free space.
if you're sliming the ath71xx target, then it's probably fairly well documented (basically you need to do a image build, and uncheck include boxes for unwanted packages)
if you need help with migrating your device to ath79, you probably should read (and perhaps write) in the thread above.
