I am on Ubuntu 18.04
with the psql (PostgreSQL) 12.2 (Ubuntu 12.2-2.pgdg18.04+1)
Running temba=# create extension postgis;
fails with the following error
ERROR: could not open extension control file "/usr/share/postgresql/10/extension/postgis.control": No such file or directory
I ran find /usr -name postgis.control
only to find out postgis.control
is inside a folder named 12
instead of 10
laptop@xyz-x:~$ find /usr -name postgis.control
/usr/share/postgresql/12/extension/postgis.control
Edit 1
I have already ran sudo apt-get install postgis

I ran this sudo apt install postgis postgresql-10-postgis-2.5
and it worked
