Did you get this with sudo ipython or ipython? What is the result of ipython locate ?
Does $(ipython locate)/profile_default have history.sqlite with the wrong rights ? (if so delete it & retry; or change permissions/owners)

Same as above with sudo ipython locate if it did not work.

We do not maintain the debian/ubuntu package, so if this is due to the way apt install it, there is nothing we can do here.

It start working by excute:

chown -R user-name:root ~/.ipython

_thank you!_

[Carreau]

chown -R user-name:user-name ~/.ipython maybe ? Don't see any reason the group should be root...

Happy hacking.

Yes, Thank you!
