Not working after re-install

I re-installed my OS and now pressing ctrl + space gives me:
`/usr/bin/env: ‘python’: No such file or directory
`
I tried removing the.marker folder and re-istalled but I still get that msg when trying to use marker:
```
joni@pop-os:~$ marker
/usr/bin/env: ‘python’: No such file or directory
```
