When i read about new developments, nightly builds, in EKOS do i manually have to upgrade my software or is it done automatically whit the upgrades of Ubuntu?
Once you have installed the nightly PPA, then updates will come with the updater on your system...but in my case I manually run it severy so often, not sure if it can be set on an auto mode, but mine does run each time the system is booted up...
Myself I don't jump on every update right off the bat. I like to wait and see the response and bug reports. Even then I maintain a raspberry pi sd card with a known working system while I test a newly upgraded one. Where I am, we get far too few clear nights to deal with new software issues.
