Strategy to deal with Canonical's increasingly poor QA?

My installed (local or obsolete) category is filling up because Canonical lately has been pushing out updates and then pulling them back. It's happened with two kernels in the recent past and it happened again with cups this morning. I've been using Ubuntu for about three years now and I do not remember this happening as often as it has this year.

So, how to rationally deal with this?

I thought about only installing updates once per week, but that would not protect against grabbing that bad update that they pushed out right before I checked that week.

Is a good strategy to only install updates on the weekend? It seems that system updates are not often pushed out on weekends. I suppose they could push a bad update on Friday afternoon and pull it on Monday morning.

Or, somehow not install updates until they have been pushed out for a certain time period - like two days? Is there an automated way to do that?

Edit: One of the affected systems runs Lubuntu 16.04 with the linux-generic kernel, the other runs Lubuntu 16.04 with the linux-generic-hwe-16.04 kernel. Both were affected by a cups version 2.13-4ubuntu0.2 update that was pushed out and then pulled back on March 27th, 2017. The linux-generic machine received a kernel update version 4.4.0.67.12 that was subsequently pulled back. This update also orphaned snapd version 2.23.1 The linux-generic-hwe-16.04 machine received a kernel version 4.8.0.42.14 that was then orphaned.

Solution 1:

The drastic alternative is to switch to Debian Stable, rather than any *buntu or derivative thereof, because Debian Stable has been through its full QA process, whereas Ubuntu is derived from Debian Testing, which has some way to go before it becomes Stable.

Almost all knowledge is directly transferable, but Debian will not give you all the latest cosmetic "bells and whistles". However, it has more packages in its repository...

I switched to Debian, in my case with KDE, coming from Kubuntu, about 5 years ago, having had similar problems. But it comes down to personal choice.
