I’m running a Proof of Concept of PureOS in VMware fusion on my Mac and testing out various tools to see if I can make the switch.
One thing I am trying to do is install Evolution Mail client with the evolution-ews plugin. Through the GUI for applications it’s listed, but not enabled and can’t select it. If I try from Bash I get "evolution-ews is not available, but is referred to by another package. ‘evolution-ews’ has no installation candidate.
Is this because I’m only hitting the Purism channels?
From what I can see, evolution-ews is not included in the PureOS repos. I’ll see if we can’t include it. It is available in Debian if you want to pull the package down from there. It will take a couple days for us to bring in a new package into PureOS.
On July 3rd this issue was requested to be included in Buster. It is now in the hands of the Debian Release team. If they do not include it in Buster (which PureOS will inherit) we will look into porting the fix into PureOS.
I haven’t seen this package in Amber indeed, but I’ve installed it from Byzantium, which is the rolling release of PureOS. As far as I can tell, Byzantium is in a beta or “release-candidate” stage and hasn’t been officially announced on PureOS website, but it is mentioned in several topics on this forum; these topics may help you make you an opinion about switching from Amber.
I’m glad I already switched to Byzantium for more recent versions of many packages, while I don’t mind daily updates, which have applied smoothly until now.
For the future you can use apt preferences to limit what upgrades you grab from a repository so that you only install the evolution related software from Byzantium (or something else from another repo) without changing your whole system.
