Need python 3.7 or greater on ubuntu server on vim1

Need to use python 3,7 capabilities, though I had been running with this on another board but ona fresh install I have

hadas@Khadas:~/david/deviceapi$ sudo apt install python3
Reading package lists… Done

python3 is already the newest version (3.6.7-1~18.04).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Am I missing something?

Should have said what was installed

khadas@Khadas:~/david/deviceapi$ cat /proc/version
Linux version 4.9.241 (khadas@b8b78b6b0b20) (gcc version 7.3.1 20180425 [linaro-7.3-2018.05 revision d29120a424ecfbc167ef90065c0eeb7f91977701] (Linaro GCC 7.3-2018.05) ) #18 SMP PREEMPT Fri Jun 25 09:27:39 CST 2021
