Many thanks guys, i think it was the " at the end of developer, but i’d already started again with version 18.04 ubuntu 18.04 using the following instructions
but get stuck after issuing the following command: bench new-site site1.local
and get the following error File “/opt/bench/erpnext/env/local/lib/python2.7/site-packages/pymysql/err.py”, line 109, in raise_mysql_exception
raise errorclass(errno, errval)
pymysql.err.InternalError: (1698, u"Access denied for user ‘root’@‘localhost’")
i have tried a few suggestions but still no luck
Thanks again, really finding my feet at the moment, with linux and Ubuntu
