If you installed the Unix Subsystem in Windows 10 previously , and already have the recent Windows 10 Creative update . It can now be upgraded to Ubuntu 16.04, open a cmd.exe window and do one of these:
remove Ubuntu 14.04 and all files in it then install 16.04 fresh
or from within the Ubuntu install itself get to root and run
first one is the safer choice... the Windows 10 Creative update is only avail for people who signed up for the windows insider program / get preview builds. .. otherwise you'll have to wait prolly a few more months for it to be released officially
remove Ubuntu 14.04 and all files in it then install 16.04 fresh
Code:
lxrun /uninstall /full /y
lxrun /install
Code:
sudo -i
do-release-upgrade;
