XFCE4 & dbus: failed to start

CiotBSD · Aug 26, 2021

Hi, all

After installed Xfce with pkgin: # pkgin install xfce4 xfce4-extras

I copy needed daemon dbus, and enable it, as wroted on installation notice!

# cp /usr/pkg/share/examples/rc.d/dbus /etc/rc.d/dbus
# ls -al /etc/rc.d/dbus
-rwxr-xr-x   1 root wheel   514  Aug 26  11:51   /etc/rc.d/bus
# grep dbus /etc/rc.conf
dbus=YES

But after rebooting, system informs me:

(…)
Starting inetd.
chown: dbus: invalid group name
Starting dbus.
dbus[598]: Unknown username "polkitd" in message bus configuration file
dbus[598]: Unknown username "polkitd" in message bus configuration file
dbus-daemon[598]: Failed to start message bus: Could not get UID and GID for username "dbus"
/etc/rc.d/dbus exited with code 1
Starting cron.
The following components reported failures:
   /etc/rc.d/dbus
(…)

This cause Xfce fails to start!

CiotBSD is your user in operator group?

yes!

It would appear that both sysutils/dbus

CiotBSD
chown: dbus: invalid group name
dbus-daemon[598]: Failed to start message bus: Could not get UID and GID for username "dbus"

and security/polkit packages

dbus[598]: Unknown username "polkitd" in message bus configuration file
dbus[598]: Unknown username "polkitd" in message bus configuration file

Failed to create their respective user/group upon installation. This should be done by pkg_add at install time, by invoking a useradd hook, providing packages were built with the PKG_USERS variable (that's the case).

The entry for the dbus user should look like: ${DBUS_USER}:${DBUS_GROUP}::System message bus:${VARBASE}/run/dbus:${NOLOGIN}
That of the polkitd user: ${POLKITD_USER}:${POLKITD_GROUP}::Polkit Daemon User:{VARBASE}/run/dbus:${NOLOGIN}

Which should result in:

$ egrep  'polkit|bus' /etc/passwd
dbus:*:1001:1000:System message bus:/var/run/dbus:/sbin/nologin
polkitd:*:1002:1001:Polkit Daemon User:/var:/sbin/nologin

If either of the 2 is missing then the installation of the packages(s) wasn't successful. It goes without saying that you may manually add the needed users and groups using useradd(8) and groupadd, but my suggestion is to try understand what went wrong and why.

CiotBSD · Aug 26, 2021

$ grep -E 'dbus|polkit' /etc/passwd
$ getent passwd dbus
$ getent passwd polkit

all return 0 information.

JuvenalUrbino to try understand what went wrong and why.

how?
If I'm not wrong, NetBSD does not keep trace of install process of the packages. Isn't-it?

pin · Aug 26, 2021

CiotBSD Force re--install dbus and polkit just to be sure there's nothing wrong with those.

Which binary repository are you using?

CiotBSD · Aug 26, 2021

pin Which binary repository are you using?

I really don't know. I Installed pkgin as recommanded, and after I dont known.

OK, I will reinstall both later. Thanks for support/help me!

pin · Aug 26, 2021

CiotBSD Check the repository in /usr/pkg/etc/pkgin/repositories.conf

Have a good night!
I will be here tomorrow.

JuvenalUrbino · Aug 26, 2021

CiotBSD OK, I will reinstall both later. Thanks for support/help me!

If anything wrong happens, remember to past here the last lines (or the relevant ones) of /var/db/pkgin/pkg_install-err.log . pkg_add will tell you to look into that file if the reinstall process fails

CiotBSD · Aug 26, 2021

Ok. I will check this tomorrow.
Perhaps, during this, you can see/analyze my pkg_install-err.log (posted on other); see: https://termbin.com/arzr

Have a good night!

JuvenalUrbino · Aug 26, 2021

CiotBSD Perhaps, during this, you can see/analyze my pkg_install-err.log (posted on other); see: https://termbin.com/arzr

useradd: Warning: home directory /var/run/dbus' doesn't exist, and -m was not specified useradd: Warning: home directory/nonexistent' doesn't exist, and -m was not specified

So it seems useradd(8) failed to create the respective home directories for the dbus and polkitd users. I'm no maintainer so @pin probably knows better why this may be happening.

pkg_add: /usr/pkg/pkgdb/pkg/+CONTENTS: No such file or directory
pkg_admin: Cannot read +CONTENTS of package pkg

This and all the analogue following errors would suggest you're dealing with a split pkgdb issue, following the package database directory change happened earlier this year (that's why pin was asking you to inspect the contents of both /usr/pkg/pkgdb and /var/db/pkg). However, given you're on a fresh install and used only the standard stable repo, this is not really likely. Moreover, your file listing of /var/db/ didn't return a pkg directory.
I wonder if there's any connection between this problem and the missing package executables you reported few days ago.

pin · Aug 26, 2021

JuvenalUrbino I'm no maintainer so @pin probably knows better why this may be happening.

So, I had a quick look at the dbus package and these should be creates when installing the package. Something really strange going on.

JuvenalUrbino · Aug 26, 2021

pin Something really strange going on.

I agree. That's also why last time I had asked OP about their filesystem integrity, the way it was mounted (in terms of options) and whether they had enabled veriexec over /usr (that was not the case). Another hypothesis could have been a global Pax SegvGuard,but again OP stated clearly they're running on a pretty much vanilla configuration.

In my roughly 5 years of NetBSD use I faced a similar problem (missing files, corrupted package database, screwed mD5 checksums, unreadable +CONTENTS) twice. The first time was after sudden power outage occurred in the middle of a package upgrade. The second time it was due to a faulty hard drive. Performing a S.M.A.R.T. test revealed a consistent and growing unreadable/reallocated sectors count.

Rrvp · Aug 26, 2021

Something is seriously messed-up with OP's setup or HW. What does dmesg show?

CiotBSD A high read error rate is considered normal on Seagate's drives. The Reallocated Sector's count is null, so I'm inclined to think your HDD is not the problem here.

CiotBSD OK I can see only 3 errors in that dmesg output (we'll skip the nouveau ones for now):

$

Can you add these lines to /boot.cfg and reboot:

userconf=disable agp*
userconf=disable bwi*

That disables the AGP port (not needed, I think) and also the wireless LAN (use the wired connection for now). I'm asking you to disable WLAN because:

$ fgrep pin ciotbsd-dmesg.txt
[     1.000968] bwi0: interrupting at ioapic0 pin 17
...
[     1.000968] ichsmb0: interrupting at ioapic0 pin 17
$

Interrupt sharing between unrelated devices may be OK with PCI, let's not do it while we're figuring out what's wrong. Plus, those are the only 2 devices that show evident errors.

You may have to re-install the system, in which case, to disable these devices before install begins, you'll have to use the userconf facility: interrupt the boot loader, then at the > bootloader prompt type boot -c. Now the kernel will boot then almost immediately drop into userconf mode. At the uc> prompt, type disable agp*, disable bwi* then quit

See if your HW behaves properly afterwards & also if pkgin works OK.

JuvenalUrbino · Aug 27, 2021

rvp That disables the AGP port (not needed, I think)

I'm positive (may as well be wrong) agp(4) is needed as a module dependency for nouveau to be loaded (dev/agp device being used to allocate physical memory for graphics), but we'll see

CiotBSD · Aug 27, 2021

rvp OK, I'll dot that in a future days. Sorry.
