Hi All,

fetchmail looks to have worked with no problems. I have submitted a patch for it.

I have also looked at python-daemon and if it is updated to the latest version then it requires a minimum python of 3.0 so that should also work fine.

I will try that package tomorrow morning.

Regards,

Adolf.

However, I have also realised that the current version of fetchmail is from 2013 and is marked obsolete so I will also do an update to the current version. Fetchmail from 2013 is definitely not a secure version to be using.

I would like to aim for Core Update 158 and remove as much stuff as possible - if we can everything - and then remove Python 2 in the update after that. If anyone has any custom scripts or applications, people will have some time to migrate away.
