usr-merge will be default

[ralul]

usr-merge (UsrMerge) is decided to be the default
I am looking for guidance how-to transit my 12y old Debian installation to the new layout.

The case for usrmerge:
https://www.freedesktop.org/wiki/Software/systemd/TheCaseForTheUsrMerge/

UsrMerge Todo for Debian:
https://wiki.debian.org/UsrMerge

The last update of the usrmerge ChangeLog shows:
usrmerge (21) unstable; urgency=medium
  * Added a version to the conflict with ebtables (see #912046).
  * Added a versioned conflict with arptables (see #916106).

Has someone tried to apply this on his installation?

Eigentlich sollte das einfach sein - einfach das Paket installieren und das wars. Wenn Fehler auftreten, dann nen RC-Bug in Debians Bugtracker malen.

Ich habe es auf meiner Frickelkiste schon gemacht, alles in Butter. Hab die installierten Pakete auch gleich wieder gekickt, weil danach nicht mehr benötigt.

Thanks for the thumbs up!

This FAQ:
https://salsa.debian.org/md/usrmerge/raw/master/debian/README.Debian
tells otherwise:

Removal of this package
~~~~~~~~~~~~~~~~~~~~~~~
The package should not be removed unless all the installed packages
among the ones listed in /etc/dpkg/dpkg.cfg.d/usrmerge have been fixed
to properly support usrmerge, or upgrading them will fail.

@hsp , Did you check the file or directory for leftovers before purging the package again?
/etc/dpkg/dpkg.cfg.d/usrmerge

[hsp]

/etc/dpkg/dpkg.cfg.d/usrmerge gibt es hier nicht. Nur /etc/dpkg/dpkg.cfg.d, und das ist leer.

Ich nehme mal an die Datei usrmerge, wenn es sie gibt, ist eine Liste mit Paketen, die vom Perl-Skript "usr-merge" nicht richtig - ohne Fehler - behandelt werden konnten. Insofern wird bei Dir alles geklappt haben.
Aber vor dem De-installieren des Script Pakets usrmerge hättest Du - nach Meinung des Faq - darein schauen sollen, ob es für alle Pakete wirklich geklappt hat
:-/
Hsp, da haste wohl nochmal Glück gehabt!

[melmarker]

Hsp, da haste wohl nochmal Glück gehabt!

erm - schon mal drüber nachgedacht, was usrmerge so tut? Mit Glück hat das nicht so viel zu tun.

und noch einer aus der Anleitung:

Removal of this package
~~~~~~~~~~~~~~~~~~~~~~~
The package should not be removed unless all the installed packages
among the ones listed in have been fixed
to properly support usrmerge, or upgrading them will fail.

Wenn liste nich da, dann alle Pakete ready. Sollte man auch für einen Freeze erwarten

[hsp]

Ich habe das ganze jetzt nochmal in einer vbox gemacht, und auch da gibt es keine /etc/dpkg/dpkg.cfg.d/usrmerge. Pakete entfernt und auch dann noch alles gut.

Nochmal Danke für den positiven Erfahrungsbericht!

I did install the usrmerge package with one little error:

Code: [Select]

Setting up usrmerge (21) ...

FATAL ERROR:
Both /bin/xrandr and /usr/bin/xrandr exist.

You can try correcting the errors reported and running again
/usr/lib/convert-usrmerge until it will complete without errors.
Do not install or update other Debian packages until the program
has been run successfully.

dpkg: error processing package usrmerge (--configure):

I did look at the files:

Code: [Select]

# /bin/xrandr --version
xrandr program version       1.4.3
Server reports RandR version 1.6
# /usr/bin/xrandr --version
xrandr program version       1.5.0
Server reports RandR version 1.6 It is what it seems, I may have had trouble in the past with the X server, when changing from proprietary nvidia to the nouveau driver, and may have copied xrandr to /bin, with a dumb thought it will help - 3 years ago.

I just rm /bin/xrandr
and installed the usrmerge package again.
All went through:
OK

After removing the /bin/xrandr file and a second install of the usrmerge
