/lib/udev/libinput-device-group errors after removing multilib

Hi all,

after removing multilib using slackpkg+ on my -current installation using the following commands:

Code:

Removed 'multilib' from PKGS_PRIORITY and from REPOPLUS, but do not the related MIRRORPLUS line
# slackpkg update
# slackpkg remove multilib
# slackpkg upgrade-all
Deleted the related MIRRORPLUS line
# slackpkg update

I experience a lot of /lib/udev/libinput-device-group errors during startup and logged in dmesg like:

Code:

If I install Multilib again, those errors are gone. Is there anything wrong in the procedure of removing multilib or do you have another idea what cloud be the root cause?

Greetings

Did you reinstall the original glibc and gcc packages? Most of the "multilib" packages are actually compat32 packages, which are the 32bit programs that are repackaged to work on a multilib system. Removing these won't affect your system at all, but you are required to replace a few core packages with their "multilib" counterparts:

Code:

* The gcc compiler suite:
  - gcc
  - gcc-g++
  - gcc-gfortran
  - gcc-gnat
  - gcc-go
  - gcc-java
  - gcc-objc

* The GNU libc libraries:
  - glibc
  - glibc-i18n
  - glibc-profile
  - glibc-solibs

I don't think an "upgrade-all" will catch that since they are likely no longer installed on the system when you removed multilib.

I have also tested it the other way around:

Code:

Removed 'multilib' from PKGS_PRIORITY and from REPOPLUS, but do not the related MIRRORPLUS line
# slackpkg upgrade-all
# slackpkg remove multilib
Deleted the related MIRRORPLUS line

with the same result.

What happens if you re-install the Slackware libinput package: "slackpkg reinstall libinput"? And then reboot?

Sorry for the late reply. I can confirm that reinstallation of libinput solved the issue.
