I manually built a debug build of Oracle VirtualBox on Linux 6.8.0-88-generic #89-Ubuntu SMP PREEMPT_DYNAMIC Sat Oct 11 01:02:46 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux (Ubuntu 24.04)

It starts up correctly but doing:

make 
sudo make install 
./VirtualBox

leads to:

VirtualBox kernel driver not Installed. 
The vboxdrv kernel module was either not loaded, /dev/vboxdrv is not set up properly, 
or you are using EFI Secure Boot and the module is not signed in the right way for your system. 
If necessary, try setting up the kernel module again by executing '/sbin/vboxconfig' as root (VERR_VM_DRIVER_NOT_INSTALLED).

Resulting code:

NS_ERROR_FAILURE (0x80004005)
Component:
ConsoleWrap
Interface:
IConsole {6ac83d89-6ee7-4e33-8ae6-b257b2e81be8}

• Secure Boot is disabled.
• I tried insmod to load them manually and give myself rights to access the devices in /dev, but this resulted in

VirtualBox kernel driver is not accessible, permission problem. 
If you have built VirtualBox yourself, 
make sure that you do not have the vboxdrv kernel module from a different build or installation loaded. 
Also, make sure the vboxdrv udev rule gives you the permission you need to access the device. 
(VERR_VM_DRIVER_NOT_ACCESSIBLE).

If anybody has an idea how to resolve this to get my debug build to boot a guest let me know. VirtualBox otherwise works correctly. It's just the kernel drivers that are irritating my nerves.

I just got Ubuntu 24.04 installed and set up, working great on my wife's HP laptop. It is about 2 years old. The only problem I have is it will not reboot after an update. It will not restart. It hangs at the HP and Ubuntu splash screen.

I can force power it off and wait a good bit then power it back on and I get to the login screen and it works perfectly again. I have done a small bit of research but found none where the Linux works but it just won't restart. There's AI slop that I have seen but I don't trust the first results in google. Thanks for any help!

I had set up Ubuntu on a Dell Latitude 5431 in July — it's my first serious attempt at making use of a Linux box in ~20 years, so I'm relatively green, but not entirely, and not afraid of some downtime and troubleshooting.

A few weeks ago, I attempted to upgrade via the GUI notification, prompting me to move from 25.04 to 25.10 — it failed, and the machine would no longer take updates for anything afterwards. I attempted the commands apt update, apt upgrade, apt full-upgrade, and now it's lost networking entirely.

I had it working well for ~5 months, long enough to get a good number of packages installed, and everything configured to my liking — thus a little reluctant to abandon it and start over. Is it a lost cause?

Priority would be to get networking back, I still have a windows machine I can use to retrieve files, but is this even viable? I don't know where to start...

If/when networking is restored, I'll then of course need to repair the install so that it can upgrade properly. Just hoping someone here can provide some guidance on where to start...

After a hard drive failure I have transferred over 10000 personally taken railway images to an SSD which is working through a Tooq hard drive reader. On attempting to edit one of these images I find that although I have read and write permissions, Group (also shown as me) is read only, as are other users - there are none. The upshot is it will not allow me to open my own image (on Gimp) but strangely it will allow me to middle about with it on XNView, as well as opening it of course. This appears to apply to all of the images.Is there a path that I can use to rectify this across the drive?. The images in folders are all that is on it.

Ubuntu 20.04 (and 22.04) on an older laptop. Stopped printing about two weeks ago. Trouble was first reported on 29 Nov; not exactly sure when last successful print was produced; it was printing when I last logged a change (change from ppd to ipp on 14 Nov). It appears that there is a conflict between the snap CUPS and the /usr/sbin CUPS and I'm failing to get one or the other, but not both, to run. (Though on my laptop, both seem to be running happily together.)

Details:

CUPS is non-responsive at localhost:631 ("Unable to connect; Firefox can't establish a connection to the server at localhost:631"). Settings->Printers displays a frowny face with "Sorry! The system printing service doesn't seem to be available"

Laptop is an older System 76 kudu running Ubuntu 20.04 patched up-to-date; printing was working fine with the wireless-connected HP Deskjet 2700 printer until about two weeks ago; I added the printer (again), this time with ipp (rather than the ppd) and all worked for several days; printer itself is still working -- my laptop (Clevo PD70; Ubu 24.04) prints on it just fine; for the record, it is also running the /usr/sbin/cupsd

Upgraded machine to Ubuntu 22.04 with no change in behaviour -- "similar" cups processes running, but no printing; no localhost:631; etc.; a number of CUPS-related processes are running, though not the same as on my laptop (which works).

syslog has fairly regular occurrences of:

<timestamp> <machinename> cupsd[<PID>]: Unable to open log file "/var/log/error_log" - Permission denied

and

<timestamp> <machinename> cupsd[<PID>]: Unable to open log file "/var/log/access_log" - Permission denied

as well as

<timestamp> <machinename> cups.cups-browsed[<PID>]: + true
<timestamp> <machinename> cups.cups-browsed[<PID>]: + sleep 3600

What is the downside of permanently disabling or evening uninstalling kvm_intel?

VirtualBox will not work if it is running.

I recently encountered an issue with my computer’s drivers, primarily relating to wifi detection. I didn’t actively apply any updates or anything, just left my computer running idle for 5 mins and came back to a black screen requiring a reboot. Upon restart, I noticed my computer no longer detects a wifi adapter.

I later realized other issues, for example I cannot change the screen brightness, the audio dial is labeled “dummy output”, and there was suddenly a dependency issue (confirmed with sudo apt-get check) that my linux-tools-6.14.0-37-generic depended on (but could not find) linux-tools-6.14.0- 37.

Note that I cannot connect to the internet in any manner from my laptop, ip link show reveals only a lo connection but no eth0 or anything else. When I run sudo lshw -c network I see network UNCLAIMED for two connections, the network controller and the ethernet controller. Here’s an excerpt: network UNCLAIMED description: Ethernet controller product: RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet Controller vendor: Realtek Semiconductor Co., Ltd.

I tried to fix this dependency issue by downloading linux-tools-6.14.0-37 from ubuntuupdates.org (note the only “linux-tools-6.14.0-37” file I could fine was listed for 25.04 Plucky not 24.04 Noble but it seemed to work nonetheless) and then running sudo dpkg -i <file.deb>, after which the dependency issue seems to be resolved. I also tried reinstalling the linux-modules-extra drivers following the advice of 22.04.1 Network Unclaimed (this fixed a similar issue I had a month previously), but saw no changes after rebooting.

I have run the wireless-info script and put the output in https://pastebin.com/1c7RZYKL.

I am having trouble with generic US keyboards in Ubuntu Studio 25.10 (questing) using Konsole in Plasma on Wayland. I have updated my packages today using apt.

The uppercase and lowercase letters often are the wrong case, despite what the caps-lock indicator shows. The Shift key does not seem to be coordinated with my typing. It frequently does not seem to update the status of the shift key when I type fast.

The plus sign on the keypad has been remapped to an equal sign. Pressing Shift on the main keyboard and plus on the keypad sends a plus sign, although the keyboards have a plus sign painted on them.

I tried System Settings > Keyboard to change the Model to "Logitech | Logitech", since that is the closest match to my external keyboard. I also tried reset to "Defaults" in "Keyboard - System Settings".

Under Accessibility, I only have "Audible Bell" and "Shake cursor to find it" enabled.

Problem persists.

I am trying to add a remote controller with only a single button to my Ubuntu 18.04 LTS device.

The controller advertises itself over BLE as an HID device. I am using a custom BLE service to manage BLE connections.

The problem is that after I connect to the controller for the first time using my custom BLE service, on subsequent connections BlueZ immediately hijacks the connection when the controller is powered on. As a result, my custom BLE service cannot even detect that the remote controller is available for connection.

Is there a way to disable this BlueZ feature that it automatically connects to HID devices on its own?

After years I had problem with the AMD driver. Discord crashed while I was sharing my webcam. I tried to update or change to the Ubuntu driver, but I am stuck.

Could not find both graphics and present queues

glxgears is working, but makes a noise on the speaker (tested this with the old driver, was not so intense. I'm not sure if it's related.)

At the moment the aim is to be able to use Discord, Steam, and Lutris again. The main window does not launch, just frees the display until I close it.

I tried to uninstall all packages, remove the PPAs that I do not need, and reboot and update and install the packages for AMD support, but that did not work too well. What have I missed? I would like to continue using Ubuntu until Ubuntu 26.04 before doing a clean install.

Edit: The Ask output, I checked the motherboard GPU, should not be configured to be used, as far as I can tell. @user7215 or what are you looking for?

New install of Server 25.04 the timezone is currently UTC. timedatectl list-timezones shows US/Pacific as a valid choice (and is what I want :-). However this command: sudo timedatectl set-timezone US/Pacific gets this result: Failed to set time zone: Invalid or not installed time zone 'US/Pacific'.

What could cause this? Seems like any timezone listed in list-timezones should work. I've seen posts about some issue with the tzdata stuff in recent releases, but no direct matches.

Thanks in advance for any help.

I'm trying to install "yfinance" on Ubuntu 24.04. Everyone on the web says to use "pip" to install, but Ubuntu gives a long message saying that's not a good idea, to use the equivalent of "apt install python3-xyz" instead.

That much is ok, but running

sudo apt-get -y install python3-yfinance

can't find anything

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package python3-yfinance

How do I point to the right repo for this?

When I do sudo do-release-upgrade to update to the next LTS, I get

Could not calculate the upgrade 

An unresolvable problem occurred while calculating the upgrade. 

The cause seems to be this (from /var/log/dist-upgrade/main.log):

WARNING Can't mark 'ubuntu-desktop' for upgrade (E:Unable to correct problems, you have held broken packages.)
ERROR Dist-upgrade failed: 'Broken packages after upgrade: ubuntu-desktop'

How do I resolve this problem? /var/log/dist-upgrade/apt.log displays too many broken packages, and I am lost on how to proceed. I know I should not delete ubuntu-desktop, what should I do?

Note, I did sudo apt update and sudo apt upgrade. Nothing reports broken packages other than do-release-upgrade. I do not think I have broken package in current version, it seems more like upgrading would cause some broken links.

I just discovered thermald for preventing machines from overheating. I'd like some basic suggestions on how to modify the xml configuration file. Below is the one I have at /etc/thermald/thermal-conf.xml. From some examples I have skimmed online, it seems it is set to start preventing overheating at 55 C (if I am reading the <Temperature>55000</Temperature> line correctly), but my cores reach even 94 C with fans going on.

I am using a Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz machine.

I have been having an issue getting an NFS share to automatically mount on boot for a handful of rpi4's all running Ubuntu 20.04.2 LTS.

If I run a sudo mount -a the drive successfully mounts with no issues.

I have tried a variety of fstab options with no success. Below is the current config:

192.168.1.100:/mnt/media /mnt/media nfs _netdev,auto,nfsvers=4 0 0

Running sudo cat /var/log/syslog | grep nfs returns the following:

Jun 24 18:59:01 test-01 kernel: [ 7.865019] Installing knfsd (copyright (C) 1996 okir@monad.swb.de).

Jun 24 18:59:01 test-01 systemd[1]: nfs-config.service: Succeeded.

Jun 24 18:59:03 test-01 kernel: [ 18.820306] FS-Cache: Netfs 'nfs' registered for caching

Jun 24 18:59:03 test-01 mount[1754]: mount.nfs: Network is unreachable

I am not sure if it is trying to mount before the network is online, but i thought the _netdev option prevented this.

I am preparing migration of an UBUNTU 16.04.7 server with 5 NIC's to 20.04. My testing server has 4 NIC's: 2 onboard and 2 as Intel Pro NIC. Configured in 00-installer-config.yaml. The first NIC is configured as:

  version: 2
  renderer: networkd
  ethernets:
    enp65s0f0:
      addresses: [10.1.11.230/24]
      gateway4: 10.1.11.11
      nameservers:
        addresses: [10.1.11.11, 1.1.1.1]
    enp193s0f0:
      optional: true
    enp193s0f1:
      optional: true
    enp65s0f1:
      optional: true

This part works. The next 3 NIC's are going to be bond0, with vlans on top and bridges:

  bonds:
    bond0:
      interfaces: [enp193s0f0, enp193s0f1, enp65s0f1]
      parameters:
        mode: 802.3ad
        lacp-rate: fast
        mii-monitor-interval: 100
        min-links: 1
  vlans:
    vlan1:
      id: 1
      link: bond0
    vlan11:
      id: 11
      link: bond0
    vlan240:
      id: 240
      link: bond0
  bridges:
    br100:
      interfaces: [vlan1]
    br11:
      interfaces: [vlan11]
    br240:
      interfaces: [vlan240]

The bond0 does not work. I have searched and tried all kinds of variations with ordering of NIC's, dhcp4: false, dhcp6: false, optional:true only using the IntelPro NIC's for the bonding. I have reviewed answers on this and other forums, but no solution so far yet.

• What's wrong with my configuration? Anything missing?
• Is the architecture I am aiming at still supported? I want my KVM guests to use a bridge so they can communicate with each other without needing the physical switch and without needing VLAN to be configured in the guests. This worked perfectly in Ub16.04.

My switch is a HP V1910-24G and has 4 other working trunks (LACP/802.3ad), with the Ub16.04 (4 NIC's)server and 3 QNAP NAS's with each a double NIC.

See the following outputs on my Ubuntu 20.04 with the above netplan config:

I am at the end of my options and ready to remove cloud-init/netplan and revert to the working configuration I had in 16.04. Thanks for reading this far.

The command

nano /etc/bind/named.conf.local

produces the error message:

The 'nano' application is not installed. You can 
install it by typing: apt-get install nano

If I type apt-get install nano the nano app still isn't installed. What should I do?

I am using ubuntu 16.04. Ubuntu 16.04 comes with python2 and python3.5 and I wanted python3.7 so I followed some instructions from a site and installed python3.7 manually by compiling its files and installing its dependencies.

It's working fine. The problem is that it is installed in usr/local/bin while I wanted it to be in usr/bin. besides I wanted python3 to point to python3.7 so I ran the following command

sudo update-alternatives --config python3

and it said that there is no alternative for python3. Besides, when I downloaded python3.7, I unknowingly unzipped it in the home directory. Now the whole python directory is in my home directory, so does that mean, whenever I make any changes like installing a library (eg. matplotlib) it will be installed directly in home/python3.7/lib?

On my ThinkPad T470 which is a dual boot with Ubuntu 18.04 and Windows 10, everything was working fine in Ubuntu until after a while I needed to boot Windows. Since then, the fan on the laptop runs constantly at full speed on Ubuntu.

I have tried the common solutions such as setting acpi_osi=!Windows 2012 in the grub setting according to this answer or setting fan speed using thinkfan according to this answer.

I have also checked my BIOS setting, but every thing looks normal as some options are set for performance and some set to be balanced between performance, energy consumption, and fan noise. The problem is Ubuntu seems to not recognize the BIOS settings or any other settings for that matter.

None of the solutions above made any difference in the fan noise.

Any help would be appreciated.

EDIT: I am suspicious about ACPI not doing its job for some reason.

EDIT 2: One observation that may be worth mentioning is that the fan runs at normal/low speed when I boot the laptop and the grub menu prompts me to choose an operating system (Ubuntu or Windows) to continue with. Then the fan takes off to full speed as I choose Ubuntu. I think this means that BIOS settings work fine.

EDIT 3: Trying to use fancontrol according to this answer, after running sudo pwmconfig, I get the following message:

hwmon3/pwm1_enable stuck to 2
Manual control mode not supported, skipping hwmon3/pwm1.
There are no usable PWM outputs.

When trying to compile pycaffe on Ubuntu 16.04, with Anaconda 3.6 installed I get the following error:

python/caffe/_caffe.cpp:1:52: fatal error: Python.h: No such file or directory

I have tried to install the python-devel packages with

sudo apt-get install python3-dev 
sudo apt-get install python3.5-dev
sudo apt-get install python3.6-dev 

But even after trying with each of those separately the same error occurs.

The correct PATH seems to be added in .bashrc

export PATH="home/jdevezas/anaconda/bin:$PATH"

And in Caffe's makefile.config I have

# NOTE: this is required only if you will compile the python interface.
# We need to be able to find Python.h and numpy/arrayobject.h.
#PYTHON_INCLUDE := /usr/include/python2.7 \
        /usr/lib/python2.7/dist-packages/numpy/core/include
# Anaconda Python distribution is quite popular. Include path:
# Verify anaconda location, sometimes it's in root.

ANACONDA_HOME := /home/jdevezas/anaconda

#PYTHON_INCLUDE := $(ANACONDA_HOME)/include \
#            $(ANACONDA_HOME)/include/python2.7 \
#            $(ANACONDA_HOME)/lib/python2.7/site-packages/numpy/core/include

# Uncomment to use Python 3 (default is Python 2)
 PYTHON_LIBRARIES := boost_python3 python3.5m
 PYTHON_INCLUDE := /usr/include/python3.5m \
                 /usr/lib/python3.5/dist-packages/numpy/core/include

I have also tried with Python 2.7 with no results. I have checked the /usr/include/python3.5m and Python.h is there. Suggestions?

My WiFi is hard blocked according to rfkill list. I have tried rfkill unblock all (although it's used for soft block/unblock).

I have checked my BIOS settings, and WiFi is not disabled there. I am not even able to turn on the WiFi service through the function key when the OS is loaded. I believe the device is working fine because all indicators blink on boot.

I am using Lenovo Thinkpad. If anyone has any solution, please suggest.

I don't remembe how boost was installed and my OS is Ubuntu 14.04.

So my questions are:

1. What method should be used to detect presence of library in the system?

2. How to completely remove boost library?

UPDATE:

Seems I managed to do it like here, but not sure if it's good way and apt list --installed | grep boost, ldconfig -p | grep boost still show presence of boost:

rm /usr/local/lib/libboost*
sudo rm -r /usr/local/include/boost

I've got a problem trying to install PHP5.5 (I need such version, because my job requires that) on Ubuntu 12.04 or 16.04 and on others Unix like operating systems such as (Mint, Xubuntu, Lubuntu).
My Ubuntu is absolutely clean, I have just installed it and tried to perform commands as all instructions say:

sudo apt-get install apache2
sudo apt-get install mysql-server mysql-client
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php5.5

But after the last command I get a conflict (in any Ubuntu like OS - Ubuntu, Xubuntu ...), and I don't know how to solve it:
Unmet dependencies during installing php 5.5 on Ubuntu

I tried to install PHP7.0 first, but that didn't help. Ondrej/php PPA should provide valid version of PHP as I thought, but what to do with that unmet dependencies?
Did anybody try to install PHP 5.5 on Ubuntu and have such conflicts with php-apcu and php-yac?

Or maybe after a New year 2016 PHP5.5 is no more supported by PPA?

I tried the guides but a window never popped up prompting me to sign in, so I continued with the command 'onedrive-pref'. That did nothing, so now I have a OneDrive folder and a .onedrive folder.

I checked my OneDrive account online; there was no new files/folders. I'm trying to get it to where I have a folder in my home folder that will sync with OneDrive online.

Under Ubuntu 14.04 I cannot get this to work.

Our PCI auditor told us we can not have direct outbound access to the Ubuntu repo's, so I mirror them with reprepro. Likewise, we do not have outbound access to keyserver.ubuntu.com.

I have tried adding each of the following to /etc/apt/apt.conf.d/99local:

APT::Get::AllowUnauthenticated "true";
APT{Ignore {"gpg-pubkey"; }};
APT { Get { AllowUnauthenticated "1"; }; };

And an "apt-get update" still returns, after reading the packages:

W: GPG error: hkp://sa1.dal.some-company.com trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 082BCA0181FE8E68

How can get this to work? Nothing I've found in the documentation on how to disable key checking works.

A lot of related posts seem to be hardware specific or due to hardware issues, which I don't appear to be having, since everything works fine so long as I setup wlan0 after boot and after logging in.

I'm a n00b to ubuntu server, so I'm hoping there's just a configuration issue at play here.

I simply want the wireless to connect after boot so I can ssh into the box and work remotely all the time.

If I setup /etc/network/interfaces with wlan0, either with static settings or dhcp, then the card appears to be setup with an IP address (according to ifconfig), but ip addr says wlan0 is DOWN, and commands to ask it to come up don't seem to do anything.

If I rem out the settings in /etc/network/interfaces, reboot, login on the actual machine, ip addr shows wlan0 to be UP, then I run sudo dhclient wlan0 then everything is fine.

An answer here: No Wi-Fi after system reboot implied there could be timing issues during boot that are at play, and that seems to fit, but I'm not sure how to troubleshoot that.

Here's /etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet static
address 192.168.1.13
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 192.168.1.1
pre-up  /etc/init.d/wpa.sh start
post-down /etc/init.d/wpa.sh stop

I tried chili555's suggestions. The changes to /etc/network/interfaces didn't affect anything. After boot, ip addr shows wlan0 to be DOWN, and various commands listed here to try and bring it up don't work.

I couldn't capture all of the output from sudo ifup -v wlan0 even with various 2>&1 >file redirects, the parts not captured was from wpa_supplicant. It didn't indicate any errors that I could tell, here's the rest from the sudo ifup command (the sudo ifdown seemed to work fine with little output):

OK
ip addr add 192.168.1.13/255.255.255.0 broadcast 192.168.1.255    dev wlan0 label wlan0
ip link set dev wlan0   up
 ip route add default via 192.168.1.1  dev wlan0

run-parts: executing /etc/network/if-up.d/openssh-server
run-parts: executing /etc/network/if-up.d/upstart
run-parts: executing /etc/network/if-up.d/wpasupplicant

But ip addr afterwards is still DOWN and I'm unable to connect. I tried sudo ip link set wlan0 up (with and without the dev bit), also sudo ifconfig wlan0 up - nothing seemed to change anything.

Running sudo dhclient ip just hangs a while then times out. There's already a static ip assigned, dunno if that would matter.

When I leave wlan0 unconfigured in /etc/network/interfaces then restart, here's what ip addr shows after boot:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet6 fe80::221:6aff:fec7:1238/64 scope link
       valid_lft forever preferred_lft forever

then running sudo dhclient wlan0 connects everything and here's the subsequent ip addr output:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

I'm trying to install Ubuntu 14.04 on my desktop I built. I am not an advanced user by any means so I just want to do the simple installation of "Install Ubuntu alongside Windows" but when I do I get the error "partition length of 5599212891 sectors exceeds the msdos-partition-table-imposed maximum of 4294967295" which I've looked around and it's the size is the problem so I then went to the option of "Something Else" and I'm not knowledgeable enough as to what types of partitions to make and how large to make them or anything. I'm looking for some help because I really want to have my desktop have both Windows and Ubuntu.
