Package: ipython3
Version: 8.30.0-2
Severity: grave

Hi. I use ipython3 regularly. After a recent update it does not work
anymore:

  dima@fatty:~$ ipython3
  Traceback (most recent call last):
    File "/usr/bin/ipython3", line 5, in <module>
      from IPython import start_ipython

                        ~~~~^^^^^^^^^^^^^^^^^^^^^
  TypeError: type 'List' is not subscriptable

"List" comes from "typing", which comes from the libpython3.13-minimal
package. I just updated that to the latest as well, and ipython3 is
still crashing.

Previously I was using ipython3 8.14.0-2, and that worked much better.
I'm about to try to revert...


Versions of packages ipython3 depends on:
ii  python3          3.13.3-2
ii  python3-ipython  8.20.0-1

You nailed it. I just updated python3-traitlets:

  Unpacking python3-traitlets (5.14.3+really5.14.3-1) over (5.5.0-2) ...

And ipython3 starts up now. I'm closing the bug. Thank you!
