Do you have a

00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (7) I219-LM (rev 10)

NIC?

Is your interface switching between down and up every few seconds?

Disabling Energy-Efficient Ethernet helped me.

Create a new unit systemctl edit --full --force disable-eee.service with this content (if the interace in question is called eno1):

[Unit]
Description=disable EEE for eno1
After=network-online.target

[Service]
Type=oneshot
ExecStart=/usr/sbin/ethtool --set-eee eno1 eee off

[Install]
WantedBy=multi-user.target

Enable it with systemctl enable disable-eee.service, reboot and check with

$ ethtool --show-eee eno1
EEE settings for eno1:
    EEE status: disabled
    ...

Running Debian 12 on a HP EliteDesk 800 G4 with

00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10)

Monitor connected via DP->HDMI and no sound?

aplay -l shows no HDMI cards:

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: CX20632 Analog [CX20632 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

dmesg shows:

snd_hda_codec_hdmi hdaudioC0D2: HDMI: pin NID 0x6 not registered

kernel cmdline options not working?

intel_iommu=on,igfx_off
snd_hda_intel.power_save=0
snd_hda_codec_hdmi.enable_silent_stream=0

Either

• Install alsa-tools-gui,
• start hdajackretask,
• for codec, select ‘… HDMI’,
• enable ‘show unconnected pins’,
• override all entries with ‘HDMI / DP’,
• ‘Install Boot Override’,
• reboot.

Or generate the files by hand:

# cat /usr/lib/firmware/hda-jack-retask.fw
[codec]
0x8086280b 0x80860101 2

[pincfg]
0x05 0x18560070
0x06 0x18560070
0x07 0x18560070

# cat /etc/modprobe.d/hda-jack-retask.conf
options snd-hda-intel patch=hda-jack-retask.fw,hda-jack-retask.fw,hda-jack-retask.fw,hda-jack-retask.fw
root@tv:~#

and reboot.

Check dmesg for

snd_hda_intel 0000:00:1f.3: Applying patch firmware 'hda-jack-retask.fw'

and that

snd_hda_codec_hdmi hdaudioC0D2: HDMI: pin NID 0x6 not registered

no longer shows.

Now aplay -l shows HDMI cards:

**** List of PLAYBACK Hardware Devices ****

  Subdevices: 1/1
  Subdevice #0: subdevice #0

  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Start pavucontrol, under ‘Configuration’ select an available HDMI profile.

Upgraded to Nextcloud 29 and seeing “Your data directory and your files are probably accessible from the internet” on your admin page?

Do you hava a redirect for any of your trusted_domains in config/config.php?

See #45087

Using DHCP on a bridge with NixOS 24.11? No longer getting an IP? dhcpcd.service failing to start? Worked with 24.05?

dhcpcd.service: Failed to set up mount namespacing: /proc/sys/net/ipv6: No such file or directory
dhcpcd.service: Failed at step NAMESPACE spawning ... No such file or directory

Seems to fail with

boot.kernelParams = ["ipv6.disable=1"];

Also there is #355450.

Does your SolrCloud successfully talk to ZooKeeper over TLS? But bin/solr zk ls fails?

In order to set custom System Properties when running any Solr utility other than start (e.g. stop, create, auth, status, api), the SOLR_TOOL_OPTS environment variable should be used.

See Setting Java System Properties.

Trying to list shares of a windows machine

smbclient -W WORKGROUP -U user -L //server.domain/
Password for [WORKGROUP\user]:
session setup failed: NT_STATUS_NOT_SUPPORTED

and failing?

Running with -d 10

Kinit for user@WORKGROUP to access server.domain failed: Cannot find KDC for requested realm
...
Failed to start GENSEC client mech gse_krb5: NT_STATUS_INTERNAL_ERROR

Starting GENSEC submechanism ntlmssp

and seeing it falling back to NTLM?

Using the REALM instead of WORKGROUP helped:

smbclient -W REALM -U user -L //server.domain/

Is ssh reporting Load key ... invalid format when trying to use a private key? The file might be missing a newline at EOF.

TIL, the Mojolicious tag helper can be nested. This

<ul class="navigation">
%= tag 'li', tag 'a', href => "#$_", $_ foreach qw/foo bar baz/
</ul>

becomes

<ul class="navigation">
  <li>
    <a href="#foo">foo</a>
  </li>
  <li>
    <a href="#bar">bar</a>
  </li>
  <li>
    <a href="#baz">baz</a>
  </li>
</ul>

Trying to install a replica on Rocky 9? Failing when setting up CA or KRA with creating installation admin user:

[3/30]: creating ACIs for admin
[4/30]: creating installation admin user
Unable to log in as uid=admin-ipa2.$domain,ou=people,o=ipaca on ldap://ipa1.$domain:389
[hint] tune with replication_wait_timeout
[error] NotFound: uid=admin-ipa2.$domain,ou=people,o=ipaca did not replicate to ldap://ipa1.$domain:389

Seems like there is a problem with password setting/synchronisation.

On the new replica, patch dogtaginstance.py:

Did you forget to add SIDs on upgrade/replica install?

This helped:
