how can I properly handle IPv6 only connections using 464XLAT, especially when certain applications or websites fail to load despite having active internet access? Are there recommended tools, configurations, or NetworkManager settings to ensure full IPv4 compatibility?

Running Ubuntu 24.04lts w/6.8.0-85 kernel and have power setting for power button set to hibernate.

When I select hibernate from the power off menu, and restore from it, it restores to lock screen (normal for resuming from standby and restoring from hibernation). My usb wifi restores back to the router where it was before hibernating.

When I use power button to hibernate, and restore from it, it restores to login screen. That also resets my usb wifi from router (where it was before hibernating) to extender. FYI - both of these also happen with newer kernels when restoring from hibernation - even when using power off menu

BTW - restore is normal using power off hibernate with 6.8.0-85/84/79/53...

I did loads of research beforehand. I was led to believe that I could just buy the PD (Power Delivery) USB-C dock and just plug it in. Unfortunately the two attached HDMI monitors go to sleep because no signal is received.

I've spent a ton of time reading up and trying out a few different things, but nothing works.

I just found a thread from 2/3 years ago where someone suggested using Xorg, but when I read up on it, this is old and outdated and Wayland is the newer and more up-to-date display system.

The brand of the dock is Ugreen. Apparently they don't provide Linux drivers because it should just work plug and play.

This is a first install of any Linux distro for me. After installation as a dual boot setup with Windows 11, I have installed Microsoft Edge successfully. I now want to install GSConnect. I have installed the Gnome shell, but when I try to install the browser connecter, I get the following error:

E: Conflicting values set for option Signed-By regarding source https://packages.microsoft.com/repos/edge/ stable: /var/lib/extrepo/keys/edge.asc != 
E: The list of sources could not be read.

I also get the identical error whatever I try to install with the sudo apt command, and also if I try to execute sudo apt update && sudo apt upgrade.

I know this is a common question, but I've tried everything I can find and can't make it work. Normally I can figure this stuff out, but I'm stumped.

Ubuntu 24.04.3 LTS, guest on VMWare Fusion on MacOS Tahoe. Shares are from a UNAS Pro.

I've followed lots of guides (as none work so far), but lets use this one which seems to be "official":

How to mount CIFS shares permanently

What is really weird to me is that the fstab etc. entries must be "right enough", as double clicking the folder mounts the drive, so does sudo mount /mnt/movies, but after rebooting I get a permissions error. I messed with some settings again last night, and now the behaviour is a reboot gives no messages, but using the Files app and navigating to the movies folder shows it as empty (no errors in the GUI). Opening terminal and issuing sudo mount -a asks for a password and returns no errors. Then the Files app shows content in the two mapped folders.

Relevant tstab entry is:

//nas.lan/Movies /mnt/movies cifs credentials=/home/plex-admin/.smbcredentials 0 0

Any help hugely appreciated. And Happy New Year!

I wanted to install and run Ubuntu from an external SSD drive. I made a dumb mistake: I used ChatGPT to give me instructions and I followed these. The SSD installed and working perfectly. I can load up and use Ubuntu, but when BIOS is set to be UEFI, the laptop won't boot into Windows 11.

I've spent absolutely ages trying to solve this problem. At first I followed loads of instructions from ChatGPT, but it was getting me nowhere. I found out that if I have BIOS set to boot Legacy, then Windows boots up, but I can't have Secure Boot. The boot menu is NOT a Grub menu. It's the original one. ChatGPT told me it was a Toshiba boot menu. The laptop is a Lenovo E490. Just thought I would mention that.

ChatGPT was saying a few things that kind of made sense... rewriting UEFI and other things, but I thought it would be best to ask here.

I tried:

• Using Macrium to restore an entire image I backed up before doing anything. It restores, but the boot menu stays the same.

• There's an option on Macrium to fix the boot menu, but running it didn't work.

This seems to have been asked before:

• Dell XPS 13 9310 sleep mode issues
• https://www.dell.com/community/en/conversations/linux-general/xps-13-9310-ubuntu-deep-sleep-missing/647f8daff4ccf8a8dee4f308?page=6

I had stuck to 18.04 LTS for a long while. I finally "upgraded" to 24.04.3 last month. The suspend/sleep was fine with 18.04, but now it drains within two hours. There are other issues after the upgrade, but this one is the most vexing.

I'm curious to know if there have been any attempts to solve this recently.

Any attempt to use the pcal (calendar generating) program results in

Cannot find system paper name

Even "pcal -v" and "pcal -P letter"

This is the first time I have tried to use it.

It was installed from the repository. Version: 4.11.0-3build1

Ubuntu Release 20.04.6 LTS (Focal Fossa) 64-bit

How do I get pcal to run?

I have a new install of Ubuntu 24.04. I installed TradingView from the terminal with sudo snap install tradingview. It installs, but when I click on the icon it doesn't start. What am I missing?

Good day everyone!

I recently built myself a new PC with a MSI 840 Gaming+WIFI motherboard and running Xubuntu, kernel version 6.17.0-8-generic.

Everything seems to be working flawlessly, but for whatever reason the system doesn't recognise the integrated WIFI card. Its not showing up using either lspci or lsusb (output attached below) and I suspect it is a driver issue. However "Additional Drivers" only shows Nvidia drivers related to the graphics card.

Its not a huge problem since I have another USB WIFI adapter which works well, but I was wondering if anyone ever had similar problems. Curiously the integrated bluetooth and ethernet also works fine, its just the WIFI thats giving me a headache.

I'm still fairly new to linux, and have only used Mint before. Since I wanted to try Xubuntu anyways and from what I read Mint doesn't support the newer kernels which can also lead to driver issues, I decided to switch.

If anyone has any similar experiences or ideas on how to troubleshoot this I would very much appreciate any input :)

I did a trial install (USB) of Ubuntu and liked it, so I did a full installation and the installed apps, etc. are not the same, missing the office, browser, tools, etc. that were on the trial screens. How do I get the system to look/act like the trial version?

as i am trying to delete files on ext hds, go as usual right clicking and...no delete option appears on the menu. All permissions are in check properly.

Any clue? Am on Ubuntu 23.10 Mantic.

Cheers & happy new year 2026 about to be! 🥳

I bought an Anker Soundcore 2 bluetooth speaker. Initial setup worked, the device was recognized by Blueman (after a bit of fiddling) and paired. After a few hours of trouble-free sound and operation, the connection suddenly dropped and I got this message:

Connection failed: br-connection-page-timeout

I've tried:

• Disabling and re-enabling Bluetooth.

• Running systemctl restart bluetooth.service

• Manually removing the device from Blueman in the hope of reconnecting it.

Now, Blueman doesn't even find the active Soundcore 2 when searching; the field remains empty. On my phone, I can easily find the Soundcore 2 as a Bluetooth device and connect to it. What could the problem be on Lubuntu 24.04?

I just got a new PC and installed dual boot Windows and Ubuntu 24.04. Everything seemed to be going well until I got some disk space issues. I tracked this down to /var/log syslog . and kern.log which are showing the following issues:

syslog:

Initially both logs were up to 45gb each, resulting in Ubuntu not being able to boot up. Journal logs are also fairly sizable at 4GB, but less of an immediate issue. Syslog and kern.log are still both creeping up in size, but I've cleared them with:

sudo sh -c 'echo > /var/log/syslog'

sudo sh -c 'echo > /var/log/kern.log'

I'm aware this is only temporarily keeping things going. I've looked into logrotate and may set that up, but it seems that there's a broader issue with "pcieport 0000:00:1c.0: AER". I don't know what this is though or have any idea of how to fix it.

Is anyone able to help me with this? My command line skills aren't great and I don't really have and understanding of what's going on with these processes other than something with pcieport is throwing up unresolved errors and they're building up and taking over memory that I want to use for other things.

I'd really appreciate any clear advice, explanations or solutions.

EDIT - taking suggestion from the post steeldriver linked here is additional data:

Memory card brand is 'XUM' which isn't on the Asus memory/device support list. It seems to be a UK based manufacturer with production in China, also trading as 'Dr Memory', upcycling chips from electronic waste sources https://www.scaleupinstitute.org.uk/stories/xum/

I installed dkms and ran it, but it returned nothing, so I take it that means I don't have it.

My wifi keeps disconnecting and reconnecting at random. I've tried many things to fix it. My wifi adapter is:

62:00.0 Network controller: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter (rev 02)

It seems to be connected to suspending the system when the lid is closed. Sometimes it will just gradually lose more and more wifi detections around me until only my home wifi is left, then when I suspend it, nothing is there at all.

So far, I've tried:

1. Using sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf, changing wifi.powersave to 0 and 2, with no success.

2. A script I found online:

#!/bin/bash

# Function to set power save for a given interface
set_power_save() {
    local interface=$1
    local state=$2
    echo "Setting power save to $state for $interface..."
    
    if sudo iw dev $interface set power_save $state; then
        echo "Power save set to $state for $interface using iw command."
    else
        echo "Failed to set power save using iw command. Please check your permissions or wireless interface status."
        return 1
    fi
}

# Function to get and display power save status
get_power_save_status() {
    local interface=$1
    local status=$(iw dev $interface get power_save | awk '{print $3}')
    echo -n "$interface: Power save: "
    if [ "$status" = "on" ]; then
        echo "on"
    elif [ "$status" = "off" ]; then
        echo "off"
    else
        echo "unknown (raw output: $status)"
    fi
}

# Function to make changes persistent
make_persistent() {
    local state=$1
    echo "Making power save settings persistent..."
    
    # Create a script to be executed by the service
    cat << EOF | sudo tee /usr/local/bin/set-wifi-power-save.sh > /dev/null

echo "Changes should persist across reboots."
echo "You can check the status of the persistent service with: sudo systemctl status wifi-power-save.service"
echo "If issues persist, check the system logs with: sudo journalctl -u wifi-power-save.service"

I since disabled this script''s effects after it caused issues switching from network to network and made network discovery impossible after toggling wifi with:

sudo systemctl disable wifi-power-save.service

sudo systemctl stop wifi-power-save.service

sudo rm /etc/systemd/system/wifi-power-save.service

sudo rm /usr/local/bin/set-wifi-power-save.sh

sudo systemctl daemon-reload  
  

3. I tried switching to ipv6 only from the network settings, which seemed to work, but it's hard to tell given the randomness of the disconnections. It's also just not sustainable.

4. I tried forgetting and re-adding the wifi, and the issues eventually continued.

5. I heard that messing with the kernel might fix it, but this also doesn't seem like a sustainable solution and typically applies to older wifi cards, where this laptop is a higher end modern model.

6. I've settled at the moment with leaving powersave-on.conf set to 3 and just doing ipv4 only, but again, this is likely not sustainable long term.

7. The issue had oddly stopped occurring with both ipv4 and ipv6 enabled. I renamed the SSID to something else, then went to saved networks in wifi settings and forgot them all, then rebooted and re-added the network. There were no disconnects for about a day before it started back up. All settings are more or less unchanged otherwise, including power saving. I also ran some commands to clear out some network settings before it resolved. I created this shell script to automate the process in future, also including instructions to navigate to settings to clear saved networks before rebooting, however, it should be noted that this is apparently a limited solution:

#!/usr/bin/env bash

set -e

echo "Stopping NetworkManager..."
sudo systemctl stop NetworkManager

echo "Removing NetworkManager system connections..."
sudo rm -rf /etc/NetworkManager/system-connections/*

echo "Removing NetworkManager state files..."
sudo rm -rf /var/lib/NetworkManager/*

echo "Removing wpa_supplicant state..."
sudo rm -rf /var/lib/wpa_supplicant/*

echo "Removing user NetworkManager cache..."
rm -rf "$HOME/.cache/NetworkManager"

echo "Starting NetworkManager..."
sudo systemctl start NetworkManager

echo "Go to WiFi settings -> Saved Networks, and remove all networks."
read -rp "Press Enter to reboot."

echo "Rebooting system..."
sudo reboot

8. Trying a slight modification of the last script, simply adding the powersave change and removing the known wifi networks before doing anything else. Same result. Works at first, but inevitably fails.

#!/usr/bin/env bash

set -euo pipefail

CONF="/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf"

read -rp "Go to WiFi settings -> Saved Networks, and remove all networks. Then press enter to continue. The system will reboot when completed."

echo "Setting wifi.powersave = 2."

# Ensure config directory exists
sudo install -d -m 0755 /etc/NetworkManager/conf.d

# Ensure file exists without overwriting
sudo touch "$CONF"

# Update only the wifi.powersave line, or append if missing
if sudo grep -Eq '^[[:space:]]*wifi[.]powersave[[:space:]]*=' "$CONF"; then
  sudo sed -i -E 's/^([[:space:]]*wifi[.]powersave[[:space:]]*=[[:space:]]*).*/\12/' "$CONF"
else
  echo "wifi.powersave = 2" | sudo tee -a "$CONF" >/dev/null
fi

echo "Stopping NetworkManager..."
sudo systemctl stop NetworkManager

echo "Removing NetworkManager system connections..."
sudo rm -rf /etc/NetworkManager/system-connections/*

echo "Removing NetworkManager state files..."
sudo rm -rf /var/lib/NetworkManager/*

echo "Removing NetworkManager runtime files..."
sudo rm -rf /run/NetworkManager/*

echo "Removing DHCP lease files..."
sudo rm -rf /var/lib/dhcp/*

echo "Removing wpa_supplicant state..."

echo "Rebooting system..."
sudo reboot

9. Upgraded the kernel to the newest 6.18.1. I upgraded using Mainline, installed with:

sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update
sudo apt install mainline

However, the problem quickly returned.

10. Reinstalled the OS. Still occurs. Also ruled out the Connectivity Checking setting.
11. Running out of things it could be outside of Ubuntu itself. Starting to consider it may relate to VPN settings. The wifi itself would disconnect typically, which is why it wasn't considered previously. The same VPN also works fine on two other PCs I have running Ubuntu. May potentially relate to the VPN connecting initially with the DAITA setting without supplying a registered VPN connection (i.e. when Ubuntu shows the VPN toggle in the top bar). The previous installation on this PC never had the VPN active without DAITA, which may have been different than the other PCs. Update, didn't work.
12. Tried editing /etc/default/grub to include pcie_aspm=off in the GRUB_CMDLINE_LINUX_DEFAULT line. Breaks the wifi even more extensively.
13. Tried Ubuntu LTS. Same issues. I hope this gets fixed soon.
14. Switching to iwd after a fresh install fixed it, but caused other issues.
15. Switched to Zorin. Their community helped me find the answer.

I did a reboot after each fix attempt. This is extremely frustrating. I have no idea what's left to try. Can anyone please help?

I have HP AMD Ryzen 7 laptop and recently installed a dual boot mode of Windows 10 and Ubuntu 20.04. Most of the time I'm using Ubuntu. Nowadays I'm getting an ACPI Bios Error during GRUB booting and restarting again and again. I selected Advanced option for Ubuntu listed in GNU GRUB menu updated GRUB_CMDLINE_LINUX_DEFAULT="intremap=off" in /etc/default/grub and rebooted my system. Now I can login to my Ubuntu operating system, but each and every time I'm performing this when I restart my system which is very much annoying. Is there any permanent solution for this ACPI Boot error?

I have been struggling to get snmp to work consistently on Ubuntu 20.04. I started on one server and finally got an snmpd.conf configuration that worked on it. I then installed snmp on a number of other Ubuntu 20.04 servers and put the working snmpd.conf file on them but some of them work and the others don't. For the systems that don't I have tried running snmpwalk -v1 -c . It works when I run the command on the servers themselves but when I run it from a different server I get "Timeout: No Response from ".

Output from netstat -an | grep 161 shows "udp 0 0 0.0.0.0:161 0.0.0.0:*" on all my servers

I can ping the servers from the server that I am running the commands from and I have confirmed that the systems' firewalls are allowing access to port 161. In fact, I have disabled ufw on a couple of the servers just to see it that would make a difference and it didn't. Has anyone else run into this? And more importantly, how did you resolve it?

During the startup a wifi connection is established and everything works fine.

After a while, the connection disappears suddenly.

To fix this i do, sudo service network-manager restart and then my connection is up. But the same problems happens after a while.

I am not sure what is the issue with the wifi-driver.

Also there is a question mark on the wifi icon. So, it more looks like a DNS issue. Also i noticed that sometimes a few sites open and sometimes none of the sites work.

This is really annoying problem and any fix is very appreciated.

There seems to be a similar issue here: Wireless connection fails every few minutes

But the accepted solution there does not work for me. The root cause could be different. Many places this issue is reported but never there had been a fully working solution. Hopefully we could fix it here!

I need an easy explanation because I am very new to Linux and I want to use an app that makes use of qt5 as requested by their website.

Installing ubuntu server 20.04 via live cd. I am at the network setup

Manual setup static ip (I am using public IP Address) and i get the error shown after entering the IP

subnet: 255.255.255.224/27

Address xxx.xxx.219.146

xxx.xxx.219.146 is not contained in 255.255.255.224/27

Gateway xxx.xxx.219.132

This of course is incorrect as it is contained in the subnet The IP range is from xxx.xxx.219.128 through to xxx.xxx.219.159

Useable IP's are from xxx.xxx.219.132 - xxx.xxx.219.158

You cannot proceed with the setup as it does not allow you to with the above error. Unless you select DHCP which i do not use. As it also does not get assigned an IP from DHCP the interface is auto disabled.

Any ideas on where i am incorrect or work around would be greatly appreciated :) Thanks in advance

I'm on Ubuntu 18.04 I believe. I've recently started a new Minecraft server, and it works just fine locally and from another desktop (connected with the ip4), however when I try to connect with the public IP address + port (example) 165.242.53.1:25565 it doesn't show.

I'm sure that I port forwarded well (I already ran a Minecraft server several times on Windows), but I just can't figure out why it doesn't work.

I run win10 with 18.04LTS VM on virtual box. I am not experienced in VM's but have a need for Linux (personal use) so I thought vBox was the only solution.

I have 2 discrete graphics cards so I want to passthrough one of these to the Ubuntu VM (also for my application to leverage this, and to explore/learn from using the GPU HW).

I believe my hardware is all supported (CPU / 2xGPU's discrete / Motherboard w/VT-D) but I cannot find a clear guide for my goal: GPU passthrough to Ubuntu VM.

My questions:

1. Does this work? (GPU passthrough win10 host --> ubuntu 18.04LTS guest)
2. Is there a clear tutorial/guide on this?
3. KVM or vBOX? (I have a vague impression KVM, which I have no experience with, is the better solution)

Any other help or feedback would be greatly appreciated

Update: 5/31/2020

I just wanted to make clear that I am not using this environment for gaming. I work mostly from win10, but want to accelerate Matlab and Python inside my Linux guest w/GPU pass-through.

After some further reading, I'm unable to determine if virtualbox has any solution for my guest/host. Instead, it might seem VMware vSphere or Workstation-Player might support pass-through.

I'm not sure why I'm running into this error since I'm have sudo -H pip install <package> before running the cron job.

Also, here are is the content of my bash script and the python scripts that it references:

Bash:

#!/bin/bash

python feature_engineering.py 
python generate_churn_outputs_actionable.py 1

Script 1 and 2:

#! /home/ec2-user/anaconda3/envs/JupyterSystemEnv/bin/python

Any help would be much appreciated. Also, if I'm missing any details, let me know and I'll add it.

I have dual boot system with Windows and Ubuntu.

• Distributor ID: Ubuntu
• Description: Ubuntu 18.04.3 LTS
• Release: 18.04
• Codename: bionic

All of a sudden my ubuntu terminal crashed and won't start, so I did a system reboot. But now on system reboot I am getting end kernel panic- not syncing:attempted to kill init! exit code=0x00000100.

Please help how can I start my system without losing any data.

It seems in 19.10 the touchscreen 2 finger zoom is finally working correctly out of the box. So why is same behavior not on the touchpad? Is there any driver, software, Ubuntu flavor, Linux distribution that can achieve this? This is the only thing that stops Linux from being my daily driver. Thanks in advance!

My fingerprint sensor is detected on my HP Elitebook 840 G2

Bus 002 Device 004: ID 138a:003f Validity Sensors, Inc. VFS495 Fingerprint Reader

yet I do not have the option under my user account to enable fingerprint. Searching for fingerprint points me to user settings without the prompt.

I am asked to setup a Touchscreen to work on a desktop install of 18.04. For now I have choosen the minimal install mode. I have tried as much as I could find to calibrate the touchscreen/-pad to work properly, but it does not work.

$ xinput

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ PS/2 Generic Mouse                        id=12   [slave  pointer  (2)]
⎜   ↳ MicroTouch Systems, Inc. MicroTouch USB Touchscreen - EX II   id=10   [slave  pointer  (2)]

That last item in the list is the subject here.

I have installed and used xinput_calibrator what told me to include the following in: /usr/share/X11/xorg.conf.d/99-calibration.conf

Section "InputClass"
  Identifier    "calibration"
  MatchProduct  "MicroTouch Systems, Inc. MicroTouch USB Touchscreen - EX II"
  Option    "MinX"  "11516"

  Option    "SwapXY"    "0" # unless it was already set to 1
  Option    "InvertX"   "0"  # unless it was already set
  Option    "InvertY"   "1"  # unless it was already set
EndSection

I have done that a rebooted but there is still some overall offset and the y axis mirrored.

Most of the steps are taken from here but that is for ubuntu 12.04, so i guess outdated. There, the author suggests to put the config into: /usr/share/X11/xorg.conf.d/10-evdev.conf but that file does not exist and all the »evdev« stuff doesn't seam to be on the system at all.

What can I do here ???

Thanks in ahead…

UPDATE

based on some further research:

$ xinput list-props 

Device 'MicroTouch Systems, Inc. MicroTouch USB Touchscreen - EX II':

Device Product ID (266):    1430, 1

Whereby the Entry Coordinate Transformation Matrix is a result of a xinput set-prop. Since the touchable Area should be the same as the display area, the transformation matrix should be:

1 0 0
0 1 0
0 0 1

But the y-axis is mirrored, so I have tried:

1  0 0 
0 -1 0
0  0 1

But that did not work…

How Can I find the touchable area?

Already happened time ago but I cannot remember the solution (remove some in home directory, I think).

I cannot unlock some panels like the "User Accounts" even though I am an administrator.

Also since yesterday, after an update, I am forced to use Unity as the metacity session shows an empty desktop.

I have an Nvidia GeForce 9800 GT card and suddenly after some recent updates on 12.04, I am unable to get my resolution higher than 1024x768. It used to be 1440x900. I have tried uninstalling and reinstalling the Nvidia drivers several times and ways, and still have not found any solution. My current driver version is 295.49 and it says my display is a CRT. I don't understand why it thinks I have a CRT. My monitor is a Samsung SyncMaster 940BW. Any help would be greatly appreciated. Thanks in advance!

UPDATE: I have a second computer that has now done this on the same monitor and it has a different graphics card. The second computer was affected immediately after applying the most recent updates for 12.04. Could this just be a bug in one of the updates? Are others experiencing similar problems with different types of graphics cards? Just a thought.

Also, on the first computer (Nvidia) I did a complete reinstall. The best I could get was 1024x768 after installing the Nvidia current drivers. I held off on updating the computer to see if I could get a higher resolution but I couldn't. Then I updated the fresh install with the latest 12.04 updates and now I can only get a resolution of 640x480. Any ideas? Both systems are running 12.04 64 bit.

Also, after the reinstall I'm currently running 295.40 version.
