pip3 install --user dvc

line reports error.

python3-dev seems to be installed

~$ apt install python3-dev

python3-dev is already the newest version (3.6.7-1~18.04).
The following packages were automatically installed and are no longer required:
  libc-ares2 libhttp-parser2.7.1 libnetplan0 libuv1 nodejs-doc python3-netifaces
Use 'apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

but there is no python3.8 under /usr/include

/usr/include$ ll | grep python
drwxr-xr-x  2 root root   4096 Nov 10 11:30 python2.7/
lrwxrwxrwx  1 root root     10 Oct  8 12:12 python3.6 -> python3.6m/
drwxr-xr-x  2 root root   4096 Nov 10 11:30 python3.6m/

so an apt update and apt install python3.8-dev is required before pip3 install --user dvc

Yep. We need to totally redo the interactive scenarios indeed. Nice to get some details here but probably no need for very specific issues since we have #1400. Closing in favor of that but thanks!
