[solved] systemd and udev block

Message

floppes · Post by **floppes** » Sat Aug 23, 2014 10:26 am

After searching the forums for about an hour without finding a solution I need to open a new thread about systemd and udev blocks. I am using Gnome and systemd and I want to keep using systemd (in contrast to most other posts with this blocking issue). I get the following:

Code: Select all

floppes-laptop ~ # emerge -uDpt world

These are the packages that would be merged, in reverse order:

Calculating dependencies... done!
[nomerge       ] virtual/udev-215

[blocks B      ] sys-apps/gentoo-systemd-integration ("sys-apps/gentoo-systemd-integration" is blocking sys-fs/udev-215-r1)
[blocks B      ] sys-fs/udev ("sys-fs/udev" is blocking sys-apps/systemd-215-r3, sys-apps/gentoo-systemd-integration-4)

As far is I understand, I need virtual/udev for sytemd but no sys-fs/udev. Why is sys-fs/udev pulled in by virtual/udev?

In short kick out udev because udev and systemd provides a similar feature but you can only have one of those on your box.

kick out udev and try to get systemd running. when you use gnome you need systemd and get rid of udev.

I don't have sys-fs/udev installed. And according to here I need virtual/udev for systemd:

sys-apps/systemd contains udev and, then, you can safely let sys-fs/udev be removed as systemd will be the provider for virtual/udev

Roman_Gruber · Post by **Roman_Gruber** » Sat Aug 23, 2014 12:00 pm

hmm, I could be wrong but does nomerge implies it is already installed?

Code: Select all

[nomerge       ]  sys-fs/udev-215-r1  USE="acl firmware-loader gudev introspection kmod -doc (-selinux) -static-libs" ABI_X86="(64) (-32) (-x32)"

please eix udev => and post hole output here, thanks, to see if its installed.

you should put that package into masking and try again,

first of all i say put sys-fs/udev into portage.mask and only keep the virtual udev package unmasked.

have you checked this sys-apps/gentoo-systemd-integration-4 <= i have no idea about this package but your first post indicates it, is it the current package? is it needed by systemd or not?

floppes · Post by **floppes** » Sun Aug 24, 2014 8:39 pm

I put sys-fs/udev into portage.mask but that didn't help...
I don't know about sys-apps/gentoo-systemd-integration either. It seems to be required by systemd.

What suddenly helped was re-emerging virtual/udev. I finally get an empty response to emerge -uDp world [:)]

Thanks for your help!

Hi,

I seem to have a similar problem, but I'm using OpenRC instead of systemd.

When I try to: emerge --update --deep --newuse --with-bdeps=y @world
this happens:

[blocks B ] sys-apps/gentoo-systemd-integration ("sys-apps/gentoo-systemd-integration" is blocking sys-fs/udev-215-r1)
[blocks B ] sys-fs/udev ("sys-fs/udev" is blocking sys-apps/systemd-215-r3, sys-apps/gentoo-systemd-integration-4)
[blocks B ] sys-apps/systemd ("sys-apps/systemd" is blocking sys-fs/udev-215-r1)

I used to have Gnome, then I removed it and installed KDE.
It seems that networkmanager requires something from systemd (dbus?), but even when I removed networkmanager,
the dependencies were still broken. Can I use networkmanager with openrc without systemd or do I have to switch to wicd?

Does anyone know how to resolve this dependency problem? I don't think removing sys-fs/udev would be a good idea in this case.

Hi Aquan89,

I was in the exact situation as you are. I am running OpenRC. I had gnome but removed it and installed KDE. When I tried world update I was getting same error.

As stated above, we can have one of systemd or udev, not both. We need to make a choice. I chose to remove systemd. So, here is what I did.

I checked what packages depended on systemd.

Code: Select all

equery d systemd
 * These packages depend on systemd:
app-admin/syslog-ng-3.4.7 (systemd ? sys-apps/systemd)
kde-base/kdm-4.11.9-r1 (systemd ? sys-apps/systemd)
media-sound/pulseaudio-5.0-r2 (systemd ? sys-apps/systemd:0[abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_ppc_32(-)?,abi_ppc_64(-)?,abi_s390_32(-)?,abi_s390_64(-)?])
net-misc/networkmanager-0.9.8.8 (systemd ? >=sys-apps/systemd-183:0)
                                (>=sys-apps/systemd-183)
net-wireless/bluez-5.18 (systemd ? sys-apps/systemd)
sys-apps/accountsservice-0.6.37 (systemd ? >=sys-apps/systemd-186:0)
sys-apps/dbus-1.8.6 (systemd ? sys-apps/systemd:0)
sys-apps/gentoo-systemd-integration-4 (>=sys-apps/systemd-207)
sys-auth/pambase-20120417-r3 (systemd ? >=sys-apps/systemd-44-r1[pam])
sys-auth/polkit-0.112-r1 (systemd ? sys-apps/systemd)
sys-fs/udisks-2.1.3 (systemd ? sys-apps/systemd)
virtual/libgudev-208 (>=sys-apps/systemd-208:0[abi_x86_64(-),gudev,introspection])
                     (>=sys-apps/systemd-208:0[abi_x86_64(-),gudev,introspection])
                     (>=sys-apps/systemd-208:0[abi_x86_64(-),gudev,introspection])
virtual/libudev-208 (>=sys-apps/systemd-208:0[abi_x86_64(-)])
                    (>=sys-apps/systemd-208:0[abi_x86_64(-)])
                    (>=sys-apps/systemd-208:0[abi_x86_64(-)])
virtual/logger-0 (>=sys-apps/systemd-38)
virtual/service-manager-0 (kernel_linux ? sys-apps/systemd)
virtual/udev-208-r2 (>=sys-apps/systemd-208:0)
x11-misc/colord-1.0.3 (systemd ? >=sys-apps/systemd-44:0)

Out of them, I unmerged gentoo-systemd-integration. I also unmerged sys-apps/systemd.

Code: Select all

emerge -aC sys-apps/gentoo-systemd-integration sys-apps/systemd

Later, emerged the systemd dependent packages with "-systemd" USE flag.

Code: Select all

USE="-systemd" emerge -av app-admin/syslog-ng kde-base/kdm media-sound/pulseaudio \
net-misc/networkmanager net-wireless/bluez sys-apps/accountsservice \
sys-apps/dbus sys-apps/gentoo-systemd-integration sys-auth/pambase \
sys-auth/polkit sys-fs/udisks virtual/libgudev virtual/libudev \
virtual/logger virtual/service-manager virtual/udev x11-misc/colord

The emerge process went smooth. I have put '-systemd' in my make.conf file and am doing @world update currently as I type. So far no problem.

I'm no expert but what I did worked for me. You can try this or as suggested above, remove udev and keep systemd. Good luck.

Hi Saivinoba

I did everything as you described and somehow systemd is still being required by networkmanager, gentoo-systemd-integration and dbus.
From this three packages, I only have networkmanager installed.
Emerging all packages that depend on systemd with USE="-systemd" didn't change anything. I wonder why.

It seems like some conspiracy to force gentoo users to use systemd

Thanks for trying to help me though, I appreciate it!

PS: AHA! Found it. I had systemd use flag in packages.use file. Now it proceeds with updates!

I got that error before (probably while emerging NetworkManager too but I'm not sure).

What I did was emerge sys-fs/udev by itself making sure that you get the exact version that emerge wants with the right use flags.
Then run your emerge again, it shouldn't need any of the udev or systemd dependencies anymore. I also set the -systemd global use flag.

I was stumped by this for quite a long time (weeks!), but Aquan89's tip to look for (and remove) systemd useflag in package.use, finally got things moving, so thanks heaps!

Glad to see you got it sorted.

For people using openrc with networkmanager and wicd, you might want to look at [topic=965190]using dhcpcd[/topic] (which you likely already have) to do it all, in conjunction with wpa-supplicant; discussed a bit later on in the topic iirc, also on the wiki.

The wiki page on dependent services might be useful too.

Damn, the wiki is kludgey with the new js nonsense.
