Comment 6 for bug 1979559

From the developer:

"Date: 2022-10-01.10:47:01

Ubuntu delivers an outdated version of eric6 as of January 2022 (i.e. 21.1). eric6 is
obsolete and no longer maintained. Furthermore it is not compatible with Python 3.10, which
causes your observation.

The solution to this is to upgrade to eric7 (latest is 22.9 with 22.10 immanent)."
