I'm on Trusty and would like to continue installing the newest mainline kernels. These started to depend on linux-base >= 4.5, while Trusty only has linux-base 3.5 in its PPAs. Is it safe to get linux-base from a xenial PPA and install it on my trusty? Could it break something?
@karel I'm specifically asking about linux-base, which is a package I don't know... it's not linux-image* or linux-headers* which are the traditional kernel upgrade packages.– Martin PeckaMay 23, 2018 at 11:23
1I think you mean “repository” instead of “PPA”.– MelebiusMay 23, 2018 at 11:35
It's safe to download linux-base 4.5 from the official Ubuntu Download Page for linux-base_4.5ubuntu1~16.04.1_all.deb and double-click the linux-base_4.5ubuntu1~16.04.1_all.deb that you downloaded to open it for installation in the Ubuntu Software Center. There won't be any dependency problems either.
Do you have any "evidence" for this claim? I mean, it may not only be about the formal dependencies od the DEB package... May 23, 2018 at 14:40
1Okay, I looked into the source package for linux-base, and it seems it's just a few perl scripts, which really should not make the system unbootable. They seem to be only used in the install phase of new kernels. I'm gonna give it a try. May 23, 2018 at 14:47
