Updating using phoebe.update_all_passbands() in Phoebe version 2.4.14 has made Phoebe inoperable and an error occurs.

I tried to uninstall Phoebe and then install any other version of Phoebe, but I encountered this error every time.

[Raindogjones]

Please uninstall the updated passbands and then try updating again using the following:

import phoebe
phoebe.atmospheres.passbands._url_tables_server = 'https://staging.phoebe-project.org'
phoebe.list_online_passbands(refresh=True)
phoebe.list_all_update_passbands_available()
phoebe.update_all_passbands()

[dingxu6207]

I've tried to operate it as you said, but I still got this error. It still doesn't work! I tried to uninstall Phoebe and then install any other version of Phoebe, but I encountered this error every time.

[Raindogjones]

Please make sure that you have fully removed any locally installed passbands (these are not removed just by uninstalling phoebe). You can check the directories in which they might be saved using:
phoebe.list_passband_directories()

[dingxu6207]

Many thanks!

Hi, I have the same problem as @dingxu6207, I have tried what they mention here but the error keeps appearing, please help.

[kecnry]

I reopened #998, let's try to keep all conversation there so anyone else running into the same issue can find it.
