[Bug 1709155] Re: Better error message for unsupported kernel
It's always bee the case that a properly configured kernel is needed for snapd to work. There even have been features added, and bugs fixed, in the kernel as a direct result of needing features working for snapd (and in those cases the Ubuntu kernel has often shipped the patches before they were upstream, and in fact there might be still patches that need upstreaming; for example I'm not sure if the fix for https://bugzilla.kernel.org/show_bug.cgi?id=195453 has been picked up or not). Just saying 'newest' carries no information as to whether the needed features are available and enabled on the kernel you're running. What snapd should do, what we're trying to have it do, is determine what features are available and use them, and work around those that are missing. This might result in some snaps not working properly or, in extreme cases, snaps running with only partial confinement (in these cases snapd should be warning about it). _This_ bug is about our failure to do this properly, at least in some scenarios. If your bug is about something else, yes you should file a new bug. However, if you run a random kernel with an arbitrary feature set, I'm not sure what support you expect beyond snapd printing a warning about things not working properly (which is this bug). ** Bug watch added: Linux Kernel Bug Tracker #195453 https://bugzilla.kernel.org/show_bug.cgi?id=195453 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1709155 Title: Better error message for unsupported kernel To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1709155/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1709155] Re: Better error message for unsupported kernel
Hmm... I see. So the misbehavior I see does not fit this bug, because this bug does not deal with the root-cause but with just an error message, a consequence of it. I've used in the past year always the newest kernels with my Ubuntu installations. They have their hickups here and there but I did never see this behavior. Snaps always worked with the newest kernels. Doesn't a bug-tracker like launchpad exist to collect the misbehavior of software, here especially Ubuntu? What do you suggest for this case.

[Bug 1709155] Re: Better error message for unsupported kernel
the title is perfectly fine, this bug is about printing a proper error instead of a cryptic readlinkat() message when there is a kernel in use that lacks the necessary features (which a proper ubuntu kernel provides) for snapd to operate correctly. in case there will be 4.18 ubuntu supported kernels (i.e. in 18.10) they will work and not print this error. it is not depending on a version (you'D likely also see it if you'd build 4.2 mainline with upstreams defconfig or some such). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1709155 Title: Better error message for unsupported kernel To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1709155/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
