=====PostGIS Issues===== 
I also checked postgres and everything seemed ok:
su researcher
#This failed too - there are unmet dependencies and they are 'not installable'.
So, option 2 is to shutdown :#Take version 10, move offline#Move version 12 10's data to a new location (/var/lib/postgresql/10/main)#Switch the right port, ports of versions 10 and load 12#Move version 12's data to /data#Put version 12 online#Load up the dbases... Then data in version 12!#Optionally wipe out the old datastructure and move the new one to the right location. installation
Shut it down:
pg_ctlcluster 12 master start
pg_lsclusters
#The cluster
Ver Cluster Port Status Owner Data directory Log file
