For the 32-bit variant of #wmlive, new Debian packages of the LTS kernel version 6.18.58 have been made available at https://wmlive.rumbero.org/repo/pool/main/l/linux-upstream , and the associated meta packages linux-{image,headers}-686 have also been provided at https://wmlive.rumbero.org/repo/pool/main/l/linux-686-meta-pkg .
Since wmlive is a compatible #Debian remix, these kernel packages can probably also be used on other 32-bit Debian/Trixie systems.
