As usual ipkg (and software like Midnight Commander) will stop work after firmware update. Solution as usual:
vi /root/.profile
ln -s /volume1/@optware /opt
. /root/.profile
mc
.profile
# add /opt/bin and /opt/sbin to PATH PATH=/opt/bin:/opt/sbin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/syno/sbin:/usr/syno/bin:/usr/local/sbin:/usr/local/bin export PATH # comment out old TERM #TERM=${TERM:-cons25} #export TERM # add new for Midnight Commander export TERMINFO=/opt/share/terminfo export TERM=xterm alias mc="mc -c"
