问题
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

postgis is already the newest version (3.0.1+dfsg-2.pgdg18.04+1).

I ran this sudo apt install postgis postgresql-10-postgis-2.5 and it worked
回答2:
I was not sure what version of postgres or postgis I needed, so I found sudo apt install postgis postgresql-postgis worked.
It either gave me the latest, or matched my installed postgres version.

I use Linux Mint and had this problem for postgres10, and also: could not access file "$libdir/postgis-2.4": No such file or directory following that. Installation of specific extension and scripts package cures it for me:
sudo apt install postgresql-10-postgis-2.4 postgresql-10-postgis-2.4-scripts Reading package lists... Done Building dependency tree Reading state information... Done postgresql-10-postgis-2.4-scripts is already the newest version (2.4.3+dfsg-4). postgresql-10-postgis-2.4-scripts set to manually installed. The following NEW packages will be installed libprotobuf-c1 postgresql-10-postgis-2.4
Then go, in my case to pgAdmin and CREATE EXTENSION postgis; returns successfully.

Alternatively, and easier, run sudo apt install postgis postgresql-12-postgis-2.5 for postgres12
