I have been trying to get linux mint to properly load to the HD of this old laptop and every time the grub installer fails. I restart it boot repair go to install again and it fails again or tells me the /root is target. I'm struggling on this one.

I am looking for a Linux application that will allow me to make a dynamic presentation showing the path of proposed bus routes. The background map shows the routes, but the advantages of the proposed network are hard to understand without a route by route comparison of the existing and proposed routes.

The report is written in LibreOffice. The professionally created map is a pdf.

I have tried LibreOffice Impress, PhotoFilmStrip, and Blender. LibreOffice Impress does not allow the background image to exceed the size of the window by more than two times, so that limits the extent that the map can appear to zoom in. Also I could not find a way to animate a route and cause the portion of the map that is visible to follow along. PhotoFilmStrip appears to zoom and pan any image, but does not appear to have an animation function. Blender is far beyond me. I got as far as learning that arranging layers in a 2D animation requires moving them in the z-axis and then resizing them.

I'm wondering why the Files app doesn't show the physical and virtual drives as in Windows.

Example: I have downloaded Helium appimage and opened it with Disk Image Mounter (as it was the default option). I looked for a virtual drive to be appear on the Files but it didn't. I ran Disks utility and saw the image was mounted but how do I access this virtual drive and run the installer there?

Update of gnome-42 and 46 in app-centre did not finish. I had the impression that 42 was not needed anymore and removed it (not clever). But firefox and app-center and so on are still using it and thus not working anymore. After all tries to reinstall gnome-42-2204 it all ends with an validation error in gnome-42-2204-226.snap.

I am actually trying Linux mint 21.2 on my old laptop. Hp elitebook 745 g2. The drivers install correctly (bcmwl-kernel-source) but it dosent list any access point. This is my first time doing a full linux install, i usually have windows together. Thanks

I use ufw on ubuntu 22.04 and I've noticed that iptables -L -v -n -x and nft list ruleset both show the same rules.

Here is what I have

# ufw --version
ufw 0.36.1
Copyright 2008-2021 Canonical Ltd.

# iptables -V
iptables v1.8.7 (nf_tables)

# nft -v
nftables v1.0.2 (Lester Gooch)

I'm trying to understand, does ufw use nftables directly or does it use iptables and rely on iptables-nft to use nftables ? Like trying to understand if ufw has been converted to be nftables native and it is creating these duplicate rules itself or if ufw doesn't even know nftables exists at all and iptables-nft allows ufw to transparently use nftables?

Does the answer change based on the version of ufw in use?

I'm new to Ubuntu, but not so new to 'IT'. I recently bought Dell-Wyse terminal, which I would like to use as my NAS. One of the apps I wanted to install is Sonarr. That went smoothly without any issues, but I'm having a problem with assigning user to specific Path. Below is my setup

This is my root folder

/media/external_ssd

Inside I have 2 folders

/media/external_ssd/personal

/media/external_ssd/Video

I created user sonarr which belongs to group media (together with my own profile)

Problem

I want to give access to the group: media only to the path: http://media/external_ssd/Video (and don't allow group media to access personal).

Attempt

I tried to do that by running:

sudo chown -R myprofile:media /media/external_ssd/Video
sudo chmod -R g+rwx /media/external_ssd/Video

But it doesn't seem to be working (I'm not able to select Video folder as root in Sonarr app).

This works only for me once I'll run chmod for all users to my ssd drive.

sudo chmod -R a+rwx /media/external_ssd

I don't want to do that, as in such case all users (including sonarr) will have access to my personal folder and I don't want that.

Do you know if I'm doing something wrong? Am I not able to give user to subfolder skipping the parent folder? Or am I messing something with the Sonarr user?

Using azerty, this should change the app to the second one in the dock, however with Wayland this types "é" in the opened window. Other [Super]+[num] shortcuts work well. For example [Super]+& opens the first app. The shortcut works well using Xorg. It seems to be a known issue, but I found no easy solution.

I can't send the image because it's too big, but here's the text that keeps popping up.

and then the same message on other line but in red.

Today, i installed meetfranz.com on Ubuntu 18.04 LTS amd64

Per accident, i noticed meeetfranz.com today. Never heard about that before.

I chose for this old, small distribution, because it's only for testing purposes.

i used the mini ISO, installed via command prompt: Open VM Tools, Net Tools, Openssh Server and client,

sudo apt-get install --no-install-recommends ubuntu-desktop

sudo apt update && sudo apt install gnome-startup-applications sudo apt install gnome-tweaks sudo apt-get install gdebi-core sudo apt-get install synaptic

wget https://github.com/meetfranz/franz/releases/download/v5.11.0/franz_5.11.0_amd64.deb sudo dpkg -i franz_5.11.0_amd64.deb sudo apt-get -f install After: sudo apt-get -f install, he corrected the previous errors !

Now, i had the startup aplications twice :-) Anyway - everything is fine.

In the settings, i set autologon, deactivated display time out.

Tested it - at startup, meetfranz is showing up, Logged in - chose for WhatsApp - running like a charm :-)

Installed: sudo apt-get install --no-install-recommends ubuntu-desktop, because, i don't need all these app's and aplications. Just hold it small - 8 GB vmdk.

Now, - WhatsApp is automatically starting, i have to remove vmware tools and open vm tools. Because, this vmdk should run on Limbo PC or Bochs for Android.

On BlackBerry 10 - Classic :-) Limbo PC and Bochs don't like installed Vm ware and open vm tools ! :-) So: now, i have to delete them...

I tried that long time ago - didn't know about uninstall these tools.. Didn't run of course - maybe this time it wil :-)

First of all, i have to free the vmdk file from these vmware an openvm tools.

Than, i can try to install on BlackBerry Classic - rep. Bochs or Limbo PC.

Because, i have to remove thesse tools anyway, i gona try to make a live iso... I'll see...

I've just started to use Zorin as my main OS and everything is really good with exception to the fact I cannot see preview for folders whatsoever. I tried many tweaks to no avail- which really bothers me considering I like to make a considerable amount of folders to keep things tidy.

The picture below quite explains what I mean. With my previous File Manager ( File Pilot ) I could see the folder's content before having to open it which was a huge help.

Is there a way to fix this?

Here's a picture as an example

Ubuntu-Mate, Ubuntu 24.04.3 LTS

An example :

pip install curl-ffi

error: externally-managed-environment

× This environment is externally managed ╰─> To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install.

If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.

If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.

See /usr/share/doc/python3.12/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages. hint: See PEP 668 for the detailed specification.

My understanding : curl-ffi must be installed global, but with the risk of breaking the Python installation I can not do it. What can I do to beware my system but also to have curl-ffi global ?

Since the upgrade to Ubuntu 24.04.3 I get logged out after exactly 10 minutes idle time.

I have done a complete reinstall to eliminate any leftovers from previous use and still get the same issue.

Screensaver is disabled (because it prevented login), power management is disabled and TMOUT is not set.

Hardware is an old Dell XPS One (A2010), Intel hardware.

At each forced logout I get a crash dump from Xorg in /var/crash.

I'd appreciate any help to investigate further.

I have just upgraded my server computer with a new chassi and a new CPU (R7 3700x -> R9 5900xt) and after moving everything into the new chassi and booting it up, everything works as normal except for the ethernet interface not showing up (ip a) nor is it working except for in BIOS. So I am certain that there is a problem with Ubuntu.

I have tried updating drivers, I tried to google what the problem is but couldn't understand/find anything to help me. Also tried checking the ethernet cable but there was no problem, and it worked flawlessly before switching chassi and CPU. The BIOS are also updated to the newest version. The led indicator where the ethernet cable is plugged in is also showing nothing (not blinking in orange nor green)

This is what I get when running the command: "lspci | awk '/[Nn]et/ {print $1}' | xargs -i% lspci -ks %" to check network cards.

My system is Lubuntu 22.04.5 LTS on a laptop.

Because I would like to keep my battery as healthy as possible, I want to make sure that the charging level stays between certain boundaries, but the hardware in my laptop does not support battery charge limits, so I turned to make use of a bash script (which I found at Github and modified it to my needs) which is called via crontab every 5 minutes. It then gives me a notification which tells me the battery charge in %, with a message warning me when it becomes to low (when the charger is not connected) or when it is too high (when the charger is plugged in), the third possibility in the notification text is that it just tells me the charge when it is between the given boundaries in the script. This works okay, but the trouble started when I added a spoken message to the script by using a line in the script that is meant to do just that.

The spoken message uses spd-say and the bash script works fine with spd-say giving the audio only when I call the script from terminal. But when the script is called from crontab it also makes the notification text appear alright, but then there is no sound at all to be heard.

I also tried aplay, which plays soundfiles and this gives a similar result, when the script is called from terminal it works, but not when called from crontab.

Here is the script, it is located at /usr/local/bin and it is called battmon.sh:

# ------------------------------------------------------------------
# Script Name:   battmon.sh

# Ensure LEVEL is a valid number
if [[ "$LEVEL" =~ ^[0-9]+$ ]]; then
    # Check for high battery level
    if [ "$LEVEL" -ge "$HIGH_THRESHOLD" ]; then
        echo "$(date) - Battery at $LEVEL%. Sending high battery notification..." >> "$LOGFILE"
        DISPLAY=:0 XDG_RUNTIME_DIR=/run/user/1000 notify-send -t 0 "Accu is vol" "De accu is nu opgeladen tot boven het ingestelde maximale niveau van $HIGH_THRESHOLD % en is nu $LEVEL % , ontkoppel de lader !" >> "$LOGFILE" 2>&1

    fi
    # Check for low battery level
    if [ "$LEVEL" -le "$LOW_THRESHOLD" ]; then
        echo "$(date) - Battery at $LEVEL%. Sending low battery warning..." >> "$LOGFILE"
        DISPLAY=:0 XDG_RUNTIME_DIR=/run/user/1000 notify-send -t 0 "Accu is laag" "De accu is nu ontladen tot onder het ingestelde minimale niveau van $LOW_THRESHOLD % en is $LEVEL %. Sluit nu de lader aan!" >> "$LOGFILE" 2>&1
        spd-say -t female1 -w "begin nu direct met opladen ! de accu is leeg, begin  meteen met opladen, want de accu heeft nog maar $LEVEL% procent lading !"
    fi 
    # Check for good battery level

I used

crontab -e

and entered this line:

*/5 * * * * /usr/local/bin/battmon.sh >> /tmp/battmon.log 2>&1

I also tried to use the cron in another way, as I understood that there is the difference in cron for the user and the system, so to try it in the system way and I did:

sudo nano /etc/crontab

and added the same line there:

*/5 * * * * /usr/local/bin/battmon.sh >> /tmp/battmon.log 2>&1

But to no avail...

At this moment I have no clue how to fix this, maybe it is not possible at all to call these sound outputting programs from crontab, but maybe someone does know how to do it right. In either case I am very curious about the why and how.

EDIT-1:

The answer knu gave seems to do a great deal of the trick, i.e. when I followed his answer and called the script from terminal everything worked, notification and sounds (I must add that strangely enough it was the notification that worked yesterday and not the sounds, but this morning it was the other way around, which I could and still can not get my head around, but after adding the line:

export XAUTHORITY=/run/user/1000/gdm/Xauthority

that was fixed (called from terminal). But in the log there was an error message "Cannot autolaunch D-Bus without X11 $DISPLAY" which was only resolved after adding the line:

export DISPLAY=:0.0

but I also saw another error in the log, note that this error only occurs when the script is called from cron, not from terminal: " GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Notifications was not provided by any .service files " for which I found a solution here

But still things are not going as wished:

1. although everything works when called from terminal, when called from cron the script does not work! (my fault: I accepted the answer as the solution, but this is still not the case...) No notification, no sound.
2. the log now shows another error (again only when the script is called from cron): "Error calling StartServiceByName for org.freedesktop.Notifications: Failed to execute program org.freedesktop.Notifications: No such file or directory"
3. After searching for a solution for the error mentioned under 2 above, I found the exact same suggestion as a solution that resolved the previous error, but of course it is clear that this does not work for this second error, because after following the solution for the first error this second one still exists !

So I was too fast in thinking this question has been resolved. I still am looking for a solution...

EDIT-2:

The missing notification has been solved by installing notification-daemon:

sudo apt-get install notification-daemon

Altough the sound output is still missing, the log now does not show any error messages after the installing of the daemon.

EDIT-3:

I did not mention this before, but I do now: I did removed the:

DISPLAY=:0 XDG_RUNTIME_DIR=/run/user/1000

that stood in front of the notification lines like in:

DISPLAY=:0 XDG_RUNTIME_DIR=/run/user/1000 notify-send -t 0 "Accu is vol" "De accu is nu opgeladen tot boven het ingestelde maximale niveau van $HIGH_THRESHOLD % en is nu $LEVEL % , ontkoppel de lader !" >> "$LOGFILE" 2>&1

because at the time I noticed that after adding

export XAUTHORITY=/run/paul/1000/gdm/Xauthority
export DISPLAY=:0.0

this was not necessary anymore, but I just found out that the suggestion that steeldriver gave in the comments was right, it was still needed before the statements that gives the speech output. So now it reads for instance:

DISPLAY=:0 XDG_RUNTIME_DIR=/run/user/1000 spd-say -t female1 -w "de accu heeft nog steeds een goede lading van op dit moment $LEVEL% procent"

Concluding:

The script that is functioning alright now on my system looks this way:

#!/usr/bin/env bash

On Software Updater's 'Software & Updates', under 'updates', I've selected 'never*' on the 'subscribe to', but security updates still keep popping up and often lock up the computer while I'm in the middle of something processor intensive, requiring holding down the power button.

I made a script to kill packagekitd (sudo systemctl stop packagekit.service), but it will reload itself and I still have to keep launching the script until it finally just quits and I can move on. It seems things like apt-check, etc. keep triggering it.

I would rather just manually do updates say once every week or two, maybe just once a month - all updates - the serious ones, security ones, and all.

Is there any way to just make it do all updates manually, other than uninstall the Software Updater app and just open terminal to use command like apt-get update, apt-get upgrade, etc.?

...the Software Updater has an option to select 'NEVER' for Automatically Check for Updates, but not for When there are Security Updates ~ the ONLY choices are 'DISPLAY...' or 'DOWNLOAD...'... and it does so right in the middle of my work :-(

I have been trying every single solution the WWW has to offer, I would appreciate if someone could please help.

I have 900 mp3 files in a folder. They are all of the same format, in that they all start with an individual number and then the song title. e.g. 2b.-29.-.'song title'.mp3, or 3c.-12.-.'song title'.mp3 etc..

This is the name of an actual file: 1a.-.114.-.season.offと.がらくーた.-.涙.\[tear\].mp3.

What I want to do is strip the first 10 characters from every file, and then just have a number ascending from 1 to 800 at the start of the file name, keeping the name of the mp3.

I have checked other examples, but not being a huge terminal guy, was unable to adapt them to my scenario. Well I possibly could but I would be at it for 24hours probably.

I have used VueScan for more than a decade, but I cannot work out what rule to set in GUFW to allow Brother on WiFi to scan via my local network to an Ethernet wired desktop running Ubuntu 24.04 LTS. The scanner works well with the firewall switched off. Lots of other services work fine with the firewall on (Samba server, Syncthing, printing, Gnome/rygel media server, etc.).

i'm getting this error on the photo i need help please:

When I open the Transmission app, I click File/Open File, and when I get to the downloads folder, I get this error. When I add a torrent file, it says "Access Denied." When I open it as a magnet, then this time app just crashes.

I am trying to install linux mint using a usb stick. I am currently using ubuntu 20.04 and I dowloaded a .zip from https://etcher.balena.io/#download-etcher. After unzipping I see something like this:

But there is nothing there that I can run,no .sh file, nothing. Do you guys know how to run this?

TLDR: Installed ubuntu 24.04 lts and suddenly my internet connection is super slow. (13Mbps compared to 580Mbps for other devices). Any suggestions?

Problem: I used to have a windows 11, moved to ubuntu. Installed 24.04lts version. Internet seems to be very very slow. Tried couple of other suggestions, such as disabling power management for wifi, update and upgrade the system. These does not seem to do the trick. When i look at the device from the router (Atnt) I see a very low link rate (30mbps) whereas every single other device falls at around 500 mbps. Furthermore, I'm using qualcom network adapter since the one that the dell alienware aurora r7 had, kind of stopped working when i changed the case since the case was too small. So in additional drivers, it shows Broadcom Inc. BCM4360 802.11ac Dualband wireless network adapter, I'm not sure if that is the correct one. The one that I am using is - Qualcomm Atheros QCA6174 802.11ac.

What steps I took?

1. Tried to disable the power management

2. Command to check the network card - lspci -nnk | grep -i net

4. Tried a couple of suggestions from here- https://askubuntu.com/questions/1230525/ubuntu-20-04-network-performance-extremely-slow

However, still no luck. Can anyone please help me. I kind of feel like I'm running in circles.

After I installed Ubuntu 20.04.4 LTS in my PC, it shows --

I'm not sure what I should do as pressing any key does nothing but closes the terminal. P.S: I'm using Windows10

I have been trying to install the mysql-server on my ubuntu server, but it just gives me this error when I type:

mysql

This is what I get:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

If I check if it is on or not with:

sudo systemctl status mysql

I get:

I have tried reinstalling, no luck. What's funny is that the mysql server works on my other linux machine, but I need it to work on this one :(

Any help is greatly appreciated!

[Edit]

pgrep -l mysql

does not return any processes

I did what @NioMarvin83 suggested. While installing, I got this:

MySQL has been frozen to prevent damage to your system. Please see /etc/mysql/FROZEN for help.

This is what's inside /etc/mysql/FROZEN:

This MySQL or variant installation has entered "frozen mode". Maintainer
scripts will avoid making changes or starting the daemon until manually
released from this state. See /usr/share/doc/mysql-common/README for
general information about this mode.

In this particular case, an incompatible downgrade attempt has been
detected. This can be resolved in one of two ways:

1. Change the contents of /var/lib/mysql/ to contain database data that
is compatible with the currently installed MySQL or variant daemon
version. For example: you could restore from a backup. Alternatively you
could do a dump using a future version binary and then a restore using
the current version binary.

2. Switch to a MySQL or variant daemon version that is compatible with
the data currently in /var/lib/mysql/. For example, if you have
attempted a downgrade from mysql-server-5.7 to mysql-server-5.6, you
could "apt install mysql-server-5.7" again.

Please resolve this situation and only then remove the /etc/mysql/FROZEN
symlink. You can then run "dpkg-reconfigure <package>" where <package>
should usually be in the form <variant>-server-<version>.

I need to restart the process. What do I do when I keep seeing these messages? Do you need more commands?

A few days ago I was in a middle of copying or cutting folders and data to my external hard drive and it was corrupted.

I have tried to locate the lost information on Test Disk but I have now lost it because it has already been over written. The file is 0. 0. copy and completed.

I have now only have the image.dd file. How can I restore this to it's normal folders and files without losing the names? Many thanks.

When I try to start MongoDB, I get this error:

I try start mongod service on console:

# service mongod start
Failed to start mongod.service: Unit mongod.service not found.

What I need to do?

My English is not so much good, please answer this question with a simple English.

This question (Permanently enabling the scroll lock button in Ubuntu?) only provides info on how to do it manually every time.

This question (How do I enable Scroll Lock?) does not offer a permanent solution (scroll lock gets disabled again soon)

Are there any permanent solutions so I can toggle it with my buttons?

I am using wimax usb modem in Ubuntu 9.04 properly. I am familiar with Ubuntu 10.04 and try to install the same deb file to use my wimax USB modem, but it could not install and give me the following error message:

The error (Line 9) give me some clue that the mt7118_usb_glue.ko kernel object can't insert it. So, I think this may be due to it's kernel dependencies.

Can anybody tell me how I can install this kernel object to my new Ubuntu 10.04 kernel?
