Of course we all here driving sid love to have all possible software in the newest available version, but do we really need it?
If there are are some tools you urgently need which are not working in the current version, but will do with an update, or an update brings features you can not do without, try to update those packages or try an upgrade/safe-upgrade.
But what is wrong on a reliable working machine to be in the state of mid July 2015, that is very current (see, people still run Win XP
). I merged to KF5 and did dist-upgrades recently in virtual machines and playboxes, but my main notebook has not seen dist-upgrades since plasma5 came in, some cherry-picked package updates only. And guess what - it is working fine. One drawback could be 'no security updates since ~ one month', but wait...
are there security updates in
Sid?
So still true: Question
... Would you recommend I still wait, or do an apt-get upgrade. ...
Answer
there are four possible ways in such situations:
1. doing nothing (prefered)
2.1. apt update; apt upgrade
2.2 apt-get update; apt-get upgrade --with-new-pkgs
3. apt-get dist-upgrade (and lettings some packages go)
We suggest and prefer 1! If one choose a way that differ from (1) one should have a good backup and should be familar with restoring from backups. We will not support that, so you are on your own. But it may work without flaws.
