Ich würd zumindest das komplette /etc/ Verzeichnis sichern. Ob du virtuelle Maschinen/Mails/Sonstwas unter /var/ zu liegen hast, dürftest du wohl wissen.

Bei einer Stretch-Neuinstallation wirst du mit den neuen unpredictable network names zu kämpfen haben. Oder auch nicht, wenn der Networkmananger dich per DHCP online macht.

Hallo NAB,
wieso das /etc-Verzeichnis sichern?
Kann da nicht was drin sein, das mir evtl. nach der Neuinstallation wieder Probleme verursacht?

Die Sachen aus /opt habe ich ins Homeverzeichnis kopiert und kopiere sie nach der Neuinstallation zurueck ins /opt.

Allerdings habe ich die config von apt-cacher ng nicht gefunden. Die muesste ich unbedingt sichern.

Ja, sicherlich kann es das. Ich sag ja nicht, dass du das gesamte /etc Verzeichnis nachher blind zurückspielen solltest. Aber wenn da noch irgendwas drin steckt, was du vor vier Jahren mal angepasst und dann vergessen hast, dann kannst du wenigstens nachgucken, was das gewesen sein könnte.

Hallo,
ich wollte mich ja nach erfolgreicher Neuinstallation wieder melden.

ER DRUCKT!!!

Nachdem ich gestern mit der Installation begonnen hatte, der Installer aber mehrere Stunden gebraucht hat, um das RAID zu Nullen, habe ich ihn ueber Nacht laufen lassen und heute dann die Installation zu Ende gefuehrt.

Als Erstes habe ich nachgeschaut, ob cups und hplip installiert sind. Sind sie und auch die hplip.conf existiert in /etc/hp

Dann habe ich im Browser localhost:631 geoeffnet und den Drucker eingerichtet und eine Testseite ausgedruckt. Jetzt druckt er wieder!!!

Allerdings verwundert mich dies hier immer noch:

Code: Alles auswählen

Warum das bei mir nicht funktioniert ist mir schleierhaft!
Aber hauptsache ist: Er druckt!

Viele Gruesse
und nochmals vielen Dank fuer eure Hilfe!

Wenn du dir mal

Code: Alles auswählen

man hp-testpage
anguckst, dann sieht mir das so aus, als ob du einen Drucker angeben musst. Zumindest beschwert er sich bei dir, dass er keinen Drucker findet, also muss man ihm wohl zeigen, wo er sich versteckt hat.

Der zweite Befehl heißt hp-check (mit Bindestrich)

Hallo NAB,

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies are installed to successfully compile HPLIP.                        
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has the proper dependencies installed to successfully run.                 
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time dependencies).

Done.

Da schein noch einiges zu fehlen, bis hp-check zufrieden ist.
Soll/muss ich das noch nachholen?

Ich hab keine Ahnung von HP-Druckern, hplip und hp-check, aber das sieht mir so aus, als ob er dir viele Abhängigkeiten listet, die du nur brauchst, wenn du hplip selber kompilieren willst.

Schau mal, was
hp-check --run
sagt.

Und im Zweifelsfall:
Er druckt doch!
Wat willste mehr?

Hallo NAB,
die ist die Ausgabe von hp-check --run:

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies are installed to successfully compile HPLIP.                        
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has the proper dependencies installed to successfully run.                 
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time dependencies).

Also für mich sieht das immer noch sinnlos aus, was hp-check da erzählt. Ich wüsste nicht, wofür du die ganzen -dev Pakete brauchen solltest, oder "make" oder "g++". Vielleicht kann sich wer anders da einen Reim drauf machen.

Solange alles läuft, würd ich da nicht mehr dran rütteln.

Allerdings verwundert mich dies hier immer noch:

Code: Alles auswählen

root@PX6-330:~# hp-testpage
warning: hp-testpage should not be run as root/superuser.

...
...
error: No device found that support this feature.
error: No installed printers found (or) Invalid printer device selected
Warum das bei mir nicht funktioniert ist mir schleierhaft!
Aber hauptsache ist: Er druckt!

Viele Gruesse
und nochmals vielen Dank fuer eure Hilfe!

Ein Blick in

Code: Alles auswählen

 man hp-testpage
tut Wunder.
hp-testpage erwartet als "default" Debianhplip-gui, die du, wie ich dich kenne, nicht installiert hast.

Wenn die nicht da, ist wäre der zweite Weg

Code: Alles auswählen

hp-testpage -i
Das sollte dann, ohne die GUI aufzurufen, mit folgenden Zeilen enden:

Code: Alles auswählen

Printing test page to printer HP_LaserJet_Pro_MFP_M125nw...
Test page has been sent to printer.

note: If an error occured, or the test page failed to print, refer to the HPLIP website
note: at: http://hplip.sourceforge.net for troubleshooting and support.
Done.
hans@sparkyxfce:~$ 
Das ergibt sich auch aus dem Code von /usr/share/hplip/testpage.py ich kann zwar die Syntax nicht , kann aber der Logik darin zumindest ungefähr folgen.
Alternativ kann man eine Testseite natürlich auch über Cups ausdrucken.

Ansonsten kann ich mich da nur NAB anschließen. Wenn alles Funktioniert - Lass es wie es ist. hp- check prüft nicht nur die Pakete, die speziell
für dich nötig sind, sondern generelle Abhängig und Möglichkeiten , wofür eventuell *.dev Pakete notwendig sind.
Irgendwo stand z.B. dass Debianwget fehlt ---> wird spätestens dann zum Problem wenn HP-GUI nach einem Update mal wieder meckert, das irgend mysteriöses Plugin fehlt, das es gerne herunterladen möchte (Bei mir Standard.- Meckerei an die ich mich inzwischen gewöhnt habe)
Nur Testing und sonst nix Xfce / KDE / Gnome / Asrock Fatal1ty 970 Performance 3.1 / AMD FX-6300 / 16GB RAM / Nvidia GTX 750 TI / HP LP3065
