P.S. I know … I need mysql 5.6 but unfortunately there is no 5.6 for my distro
may be will compile one in the future …
$ mysql –version
mysql Ver 14.14 Distrib 5.5.58, for debian-linux-gnu (armv7l) using readline 6.3
but this still does not explain why I was not able to install the plugin 🙁 , or explain ?
