If you upgrade BusyBox then /opt/bin/wget will point to /opt/bin/busybox.
This means "ipkg install wget" (to install GNU wget) will fail, as wget will want to install into /opt/bin/wget too.
However, if you move (or remove) the link to wget, then ipkg operations will fail ...
I had the same the same problem trying to install 'less' after upgrading busybox.
# ipkg install less Installing less (381-1) to root... Downloading http://ipkg.nslu2-linux.org/feeds/unslung/unstable/less_381-1_armeb. ipk Installing ncurses (5.4-2) to root... Downloading http://ipkg.nslu2-linux.org/feeds/unslung/unstable/ncurses_5.4-2_arm eb.ipk Package ncurses wants to install file /opt/bin/clear But that file is already provided by package busybox Package ncurses wants to install file /opt/bin/reset But that file is already provided by package busybox An error ocurred, return value: 2.
I will try the same advice as given above and see if it works Update - It worked!
*** Where is Wget for Unslung 6.x? ***
You just need to do 'ipkg install wget-ssl' instead. Easy!
