The repository for linux-rt and linux-rt-lts has moved to a new location.

If you use the custom repository, please update your pacman.conf accordingly, as the other one is going away by the end of the month (January 2021)!

As a heads up, I hit a strange kernel bug with Nextcloud and this last package update (linux-rt-lts-

You need to edit the PKGBUILD, to use the sources from For testing purpose I used one of my PKGBUILDs, the one I used to build the package for the kernel, that's booted at the moment. I only needed to update the version and to remove a patch. However, the comments are not the right place to teach you, how to write a PKGBUILD. For help consider to use a mailing list.

$ uname -a
Linux archlinux 4.19.193-rt81-0.300-pussytoes #1 SMP PREEMPT RT Mon, 07 Jun 2021 09:13:18 +0200 x86_64 GNU/Linux

Note my PKGBUILDs do not differ much from those provided by dvzrv, actually I compare and align the PKGBUILDs from time to time, trying to stay as close as possible. Apart from the need to use as source, I'm in favour of a different versioning pattern and KBUILD_BUILD_TIMESTAMP. Since I stay with 4.19 LTS kernels, there are a few other differences. Maybe the build wouldn't finish, but it started to build, there was just a warning due to the expired key.

Keep in mind that dvzrv provides the LTS kernel, I did not check his source, but at least 5.9 is not a LTS kernel, see

You can name the kernel what ever you want it to name, lts or pussytoes.

I want to install the rt-5.9 kernel using the current rt-5.10 PKGBUILD. I edit the pkgver variable of PKGBUILD and run makepkg. The problem of the signature occurs and remains. I have successfully complied and applied rt patch to kernel 5.9 using the traditional compiling method.

Hi, I'm not sure if I put it clearly. You want to build a lts package for a kernel, that is not a lts kernel. That's no problem, but instead of git+ you probably need to use as source for the kernel and the patch.

You need to add 57892E705233051337F6FDD105641F175712FA5B to validpgpkeys and download the key before building the package. Note, the key has expired and I assume that the source is

How can I download and compile kernel version rt-lts- I tried to change the pkgver variable of PKGBUILD of this version and do makepkg. I got this error: linux-rt-lts git repo ... SIGNATURE NOT FOUND ==> ERROR: One or more PGP signatures could not be verified!

Is it possible to remove DEBUG_INFO from the config? Looks like it is not used for the package anyway, and can increase the package size dramatically if custom packaging commands are used. Also, looks like it's not an option a regular user would want. If removed via the menu, it produces the following change in the config file:

-# CONFIG_GDB_SCRIPTS is not set
+# CONFIG_DEBUG_INFO is not set

Update - apparently, not:

OK, I have downloaded the necessary files for 5.4.x from git

blackhole commented on 2021-04-13 12:36

Do you have a compiled lts kernel 5.4.x? In your repository I cannot find it no more. (Or eventually the snapshot with the files involved)

dvzrv commented on 2021-04-13 11:46

@blackhole: Yes, my bad. I added the package files without the signatures without noticing. It is fixed now though :)
