+++ This bug was initially created as a clone of Bug #1534489 +++ Description of problem: there is some strange error about avahi? dbus? when printing, no idea why its connected Version-Release number of selected component (if applicable): firefox-52.5.1-1.el7_4.x86_64 dbus-1.10.24-3.el7.x86_64 avahi-0.6.31-19.el7.x86_64 cups-1.6.3-35.el7.x86_64 How reproducible: tried once, and its always there Steps to Reproduce: 1. rhe75 nightly, server with GUI, all default 2. add usb printer 3. firefox + print whatever page 4, I did no setup of avahi, its all by default Actual results: log shows some error: Jan 15 11:06:31 localhost dbus[689]: [system] Rejected send message, 0 matched rules; type="method_return", sender=":1.2" (uid=70 pid=686 comm="avahi-daemon: starting up ") interface="(unset)" member="(unset)" error name="(unset)" requested_reply="0" destination=":1.434" (uid=0 pid=3762 comm="/usr/lib64/firefox/firefox ") Jan 15 11:06:31 localhost dbus[689]: [system] Rejected send message, 0 matched rules; type="method_return", sender=":1.2" (uid=70 pid=686 comm="avahi-daemon: starting up ") interface="(unset)" member="(unset)" error name="(unset)" requested_reply="0" destination=":1.434" (uid=0 pid=3762 comm="/usr/lib64/firefox/firefox ") Expected results: log is without error in case of default installation --- Additional comment from Michal Sekletar on 2018-01-25 17:03:15 CET --- I was able to figure out the root cause. Problem is that avahi client (GNOME print dialog -- the issue is not specific to Firefox, evince and gedit have the same problem) calls Free() method on ServerBrowser object and in the method_call message it sets NO_REPLY_EXPECTED flag. However, avahi didn't respect the flag (avahi was written around the same time when dbus-daemon and NO_REPLY_EXPECTED flag was a newer addition to the dbus spec and daemon) and sent method_reply (OK) anyway. Our new dbus-daemon (rebased in RHEL-7.5) doesn't like that so it dropped the message and logged an error. This is not the new problem, also Fedora has the same issue. --- Additional comment from Michal Sekletar on 2018-01-29 17:11:50 CET --- Patch posted upstream, https://github.com/lathiat/avahi/pull/165 --- Additional comment from Michal Sekletar on 2018-01-29 17:13:30 CET --- Issue was always present in avahi. This isn't a regression.
I've got the same error message. I updated a computer from Linux Mint MATE 19.3 to Linux Mint MATE 20. This computer prints on a Brother-HL-3170CDW, it works. I installed Linux Mint MATE 20 on another computer in the same network, with the same 2 packages hl3170cdwlpr-1.1.2-1.i386.deb and hl3170cdwcupswrapper-1.1.4-0.i386.deb. This computer prints on the same printer, with the same protocol (ipps://192.168.1.2:443) but it doesn't work, no paper is going out of the printer, the printer LED doesn't even blink. In /var/spool/cups, 2 files d000... and c000... are created each time I'm printing : -rw-r----- 1 root lp 234 16 juil. 14:08 d00030-001 -rw-r----- 1 root lp 27 16 juil. 14:06 d00029-001 -rw-r----- 1 root lp 32 16 juil. 14:05 d00028-001 -rw-r----- 1 root lp 27 16 juil. 13:59 d00027-001 -rw-r----- 1 root lp 27 16 juil. 13:59 d00026-001 -rw-r----- 1 root lp 45830 16 juil. 13:27 d00025-001 -rw------- 1 root lp 970 16 juil. 14:08 c00030 -rw------- 1 root lp 964 16 juil. 14:06 c00029 -rw------- 1 root lp 1006 16 juil. 14:05 c00028 -rw------- 1 root lp 964 16 juil. 14:00 c00027 -rw------- 1 root lp 964 16 juil. 13:59 c00026 -rw------- 1 root lp 1395 16 juil. 13:53 c00025 In /var/log/cups/access_log/ : localhost - - [16/Jul/2020:13:20:41 +0200] "POST /printers/Brother-HL-3170CDW HTTP/1.1" 200 46523 Print-Job successful-ok localhost - - [16/Jul/2020:13:25:33 +0200] "POST /printers/Brother-HL-3170CDW HTTP/1.1" 200 94388 Print-Job successful-ok localhost - - [16/Jul/2020:13:27:20 +0200] "POST /printers/Brother-HL-3170CDW HTTP/1.1" 200 46523 Print-Job successful-ok localhost - - [16/Jul/2020:13:59:20 +0200] "POST /printers/Brother-HL-3170CDW HTTP/1.1" 200 262 Print-Job successful-ok localhost - - [16/Jul/2020:13:59:53 +0200] "POST /printers/Brother-HL-3170CDW HTTP/1.1" 200 262 Print-Job successful-ok localhost - - [16/Jul/2020:14:05:30 +0200] "POST /printers/Brother-HL-3170CDW HTTP/1.1" 200 267 Print-Job successful-ok localhost - - [16/Jul/2020:14:06:24 +0200] "POST /printers/Brother-HL-3170CDW HTTP/1.1" 200 262 Print-Job successful-ok localhost - - [16/Jul/2020:14:08:03 +0200] "POST /printers/Brother-HL-3170CDW HTTP/1.1" 200 420 Print-Job successful-ok In /var/log/auth.log : Jul 17 11:20:35 Ordinateur-David dbus-daemon[895]: [system] Rejected send message, 0 matched rules; type="method_return", sender=":1.4" (uid=119 pid=892 comm="avahi-daemon: starting up " label="unconfined") interface="(unset)" member="(unset)" error name="(unset)" requested_reply="0" destination=":1.194" (uid=1000 pid=12700 comm="xed " label="unconfined") If I print with Firefox, comm="/usr/lib/firefox/firefox " instead of comm="xed " etc. $ lpstat -t -v scheduler is running system default destination: Brother-HL-3170CDW matériel pour Brother-HL-3170CDW : ipps://192.168.1.2:443 matériel pour PDF : cups-pdf:/ Brother-HL-3170CDW accepte des requêtes depuis ven. 17 juil. 2020 11:56:21 PDF accepte des requêtes depuis ven. 10 juil. 2020 22:08:15 printer Brother-HL-3170CDW is idle. enabled since ven. 17 juil. 2020 11:56:21 printer PDF is idle. enabled since ven. 10 juil. 2020 22:08:15 matériel pour Brother-HL-3170CDW : ipps://192.168.1.2:443 matériel pour PDF : cups-pdf:/ $ ls /etc/cups/ppd Brother-HL-3170CDW.ppd PDF.ppd PDF.ppd.O $ lpstat -l -e Brother-HL-3170CDW permanent ipp://localhost/printers/Brother-HL-3170CDW ipps://192.168.1.2:443 PDF permanent ipp://localhost/printers/PDF cups-pdf:/ Anyone could help me to know where is the problem ?
