Please may I butt-in to the conversation.
In my experience, no operating system is immune from updates which break things. All of the offerings from Redmond have had, or do have, problems with updates. Linux is no different. Every linux distro I’ve used has had problems with updates, Fedora, CentOS, Debian, Ubuntu, Mint, SuSe, Slackware…they all have the same problem a bad update with break the system. I’ve even broken an NT4 system by installing bad anti virus updates.
The only difference I see between different operating systems is how well they recover from bad updates. In Redmonds case this seems to be pot luck and Linux is much the same (for the average user). Every Linux problem I’ve ever had involves accessing the terminal, so if you have a broken system then most people are finished.
I think the problem is that people expect their IT systems to work all the time. They are much better now, but they used to be awfull! (See my comment about NT4 and a bad anti virus update).
May I suggest that for those people using free software (which Linux is) it’s presented with a statement that says there is no guarantee an update won’t break the system.
If you pay for updates, that should come with reasonable confidence they will work. But even then you can’t guarantee some odd system config won’t have a problem. In my experience its “user beware” on ANY operating system, and NethServer is no different.
The only Operating system I’ve found that can recover from bad updates is Solaris and ZFS, but even that isn’t a recovery, it’s a roll back to a working config (which is how Redmond operates with their latest system recovery tools).
Sorry for interrupting the discussion, but I just wanted to highlight that every operating system has problems with updates. It’s up to the user to have system data backed up so they can re-install and carry on.
