[Bug 1854186] Re: "software-properties-gtk crashed with TypeError in new_init(): could not convert value for property `transient_for' from DialogCacheOutdated to GtkWindow" crash happened after I clicked "Reload Cache" upon checking "Software Restricted by copyright" in the Ubuntu Software Menu

[SeiK]

** Description changed:

- Upon attempting to add debug repositories to apt and then opening
- Software Updater, the cache loaded and then I switched to the Ubuntu
- Software Tab. I then clicked the checkmark next to "software restricted
- by copyright or legal issues." I then clicked the Close button, and then
- the reload button.
- 
- The window that shows the reload process became stuck and would not be
- dismissed, softlocking me in the update-manager app and forcing me to
- kill the application.
- 
- Expected Results:
- Software Update applies the changes without issue and then quits, or throws and error if that is not possible and I made a mistake
- 
- Actual Results:
- Software Update manager hangs ans softlocks me into forcing me to kill the process.
- 
- Prior to the issue occurring, I ran "echo -e "deb
- http://ddebs.ubuntu.com $(lsb_release -cs)-updates main restricted
- universe multiverse\ndeb http://ddebs.ubuntu.com $(lsb_release
- -cs)-proposed main restricted universe multiverse" | sudo tee -a
- /etc/apt/sources.list.d/ddebs.list" and then opened Software Update
- manager. I was attempting to follow the steps to debug on this URL:
- https://wiki.ubuntu.com/DebuggingProgramCrash
- 
- However, I skipped the first step in adding the debug repositories and
- added the one in the second step before opening Software & Updates.
