I am new to programming and want to understand what coding actually means. Can someone explain what coding is and which programming languages are best for beginners to start learning? I would also like to know what basic skills are needed to begin coding.
I need help and have no other option because there is no built in WiFi card
After a problem with an SSD on my ancient Dell desktop, I re-installed Ubuntu (V24.04.2 LTS), and then re-installed user files from backup. Trying to reinstall some software (UrBackup Server, e.g.) the install process failed, apparently because the Broadcom wireless driver couldn't be compiled, due to a missing header file.
There's an incredible amount of stuff on the web related to Broadcom driver issues, and after several days of trying to make sense of it all, I'm stuck. I can't even delete the Broadcom driver without the process failing due to the missing header file.
The wireless module is a BCM4313 (14e4:4727). My kernel is 6.17.0-14-generic. At the moment there is no driver reported for the wireless interface. I can live without wireless if I must, but I'd really like to be able to install software again.
Newbie here, looking to properly organise the various hard drives in my PC. I'm on a fresh 25.10 install. I have
| Name | Type | Size |
|---|---|---|
| sda | HDD | 2 TB |
| sdb | SSD | 1 TB |
| nvme0n1 | SSD | 500 GB |
During installation I went into a lengthy conversation with an AI chatbot and did the following manual partitioning:
My brain is formed by Windows and we need to change that. I am still used to being able to freely chose installation destinations. I roughly understand the advantages of Linux' filesystem but want to use my available drives as seamlessly as possible.
Now I realise I can not fill sdb (/apps) as easily as I thought. After some search, I see the following options:
What is the most Linux-esque way to do this and what are common & robust ways to organise various drives like in my example? I dont believe "have just one big drive because Linux is not flexible regarding its filesystem" is the answer. My AIchatbot warns me about LVM (advanced, risky, blablah ...).
(1) How to create a file from terminal, with specific number of empty lines; and then (2) append different strings to specific ranges of lines?
The following command (from previous question): sed -e '1,128s/^/00:0/' -e '129,713s/^/00:/' -e '714,2285s/^/0/' filename. Prefaces an existing ranges of lines, but doesn't create new lines.
This is a 2 part question, happy with 2 seperate commands, but also 1 compound command. Aim is to create different lists, e.g. Day 1 thru 20, and then append 5 push ups, 10 push ups, etc. to relevant lines.
To preface this, I am just a hobbiest tinkerer, please be gentle.
Been trying to use ChatGPT to fix this, but can't seem to get it working.
Just purchased a used Lenovo X13 Gen3. Removed the SSD and put the SSD in from my 6 year old XPS, running Linux.
Everything spooled up perfectly, except Wifi. (Yes, wifi was working on the other SSD with windows)

I'm currently trying to install python3 onto ubuntu24.04.3. I only realized that python came preinstalled with ubuntu after attempting sudo apt install python3.
I have now seemed to have permanently borked python and apt on my system. When I try to run any python operation, the system cannot find the python3command. When I try to run sudo apt install python3, I get the following output:
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
python3 : Depends: libpython3-stdlib (= 3.12.3-0ubuntu2.1) but 3.12.3-0ubuntu2 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
I tried to run sudo apt install libpython3-stdliband got the following output:

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
I thought that there might have been an issue with my apt repos, so I ran a sudo apt update. It resulted in this error:

I was referred to this post and tried running sudo apt install --reinstall python3 python python3-minimal --fix-broken. After which I got this error:
Package python is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
2to3 python-is-python3
So I tried running the same command without python sudo apt install --reinstall python3 python3-minimal --fix-broken and got the following error:
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
python3 : Depends: libpython3-stdlib (= 3.12.3-0ubuntu2.1) but 3.12.3-0ubuntu2 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
Still stuck on this.
Hardware Specifications:
Machine: Lenovo ThinkPad E14 Gen 6
CPU: AMD
OS Attempted: Kubuntu 26.04 LTS daily build
Issue Description:
I am completely stuck trying to install Kubuntu. The installation process always fails at the very end with an error window. The exact error output is:
Command cp /etc/apt/sources.list.d/cdrom.sources /tmp/calamares-cdrom-sources/ finished with exit code 1.
Output:
cp: cannot stat '/etc/apt/sources.list.d/cdrom.sources':
No such file or directory.
Troubleshooting Steps Taken (All resulted in the same error):
USB Flashing Tools:
I created the bootable USB using both Popsicle and Fedora Media Writer. Same result with both.
Partitioning:
Selected "Erase entire disk" with automatic partitioning.
Installation Type:
Tried both "Minimal installation" and "Standard/Normal installation". Network/Updates: Tried checking AND unchecking the "Download updates during installation" option.
Additional Context:
To rule out a hardware or USB drive issue, I flashed the latest Ubuntu GNOME 26.04 LTS daily build and it installed flawlessly without any errors. This seems to be a specific bug with Calamares looking for a legacy cdrom.sources file that doesn't exist in the current Kubuntu ISO.
Has anyone found a permanent workaround for this specific installer bug, or is there a way to bypass this step during the live session before running the installer?
Error message (Installation Failed):
I'm running stock Ubuntu 24.04 LTS and am having a problem with Gnome Characters version 46. For some reason, I can find special/exotic characters but can't find 'normal' characters like the ASCII characters in it. For instance, when searching equal sign in the app I see variants of the equal sign character, but not the base character with code U+003D (screenshot below).
In addition, if I exit the search and navigate to the Letters section on the left, instead of the Latin Capital Letters at the start I see the following:
Since this may be relevant, I include here the output of running locale in the terminal:

Please help! Some keys on my keyboard occasionally don't work so I want to be able to copy/paste them from the app.
I got a tplink ax3000 pcie wifi/bluetooth card for my ubuntu 24.04.4 HP-Z840 workstation PC.
Jeremy31 stopped supporting my card in their btusb driver, on github.
Because of that, I've had to completely freeze kernel updates for a while now.
Does anyone know of a replacement driver? I feel as though Ihave looked everywhere.
if you need information, don't hesitate to ask
I've nearly the last whole 4-5 days attempting to fix some issues which have started happened on my laptop. I'll explain what the original issue was and what the continuing issues are.

My laptop has been experiencing minor issues with ubuntu since I installed it. Mostly minor freezes for ~15 seconds during usage or sometimes it would lock up completely. During the times when it would freeze completely I would restart using ALT + PrtSc + REISUB.
I encountered a new issue though last Friday, when going to boot my laptop. I was met with a black screen with the keyboard lights pulsing. I gave it a few minutes but then decided to force shutdown, and every time after that, no luck, it was stuck.
The boot would always hang on "Loading initial ramdisk ..." I'll spare the rest of the details, but after trying numerous BIOS settings and grub linux options eventually I found that the only option that would get my laptop to boot was setting "intel_idle.max_cstate=1"
I figured that it might be related to my CPU being newer, but since making this change to get ubuntu to boot I've run into numerous other problems. Most notably, performance degraded significantly. My CPU frequency, under any workload, would never exceed 400 MHz. Any input was slow, (about 1/3 of a second delay). Scrolling in any application or browser felt painful.
I tried another option "intel_pstate=disable" which seemed to stop the throttling, but performance was only negligibly better. I have experimented with numerous cpupower settings and manual governing but it seems that the CPU always will fall into a idle state which seems to take over a second to wake from. Disabling idle states with cpupower just locked the frequency at 400 MHz again. Disabling thermald also seemed to stop the throttling cap, but the same issues as above remained. Anything which "repaints" a lot of the screen seems to be very slow and stuttery, and my IDE (webstorm/pycharm) is borderline unusable. My mouse takes about a second to start moving when input is given. CPU heavy tasks are also noticeably slower. All of these things worked great outside of freezing issues before this.
My BIOS is up to date and I have latest graphic drivers, I think. All of my power/governor settings are set to performance as far as I am aware. My thermals are also pretty normal, almost never goes above 70 C.
Is this caused by setting max_cstate to 1 or are there other issues that I should diagnose? Any help is greatly appreciated.
P.S. I'm pretty new to Linux, so please correct me if I'm confidently wrong about something. I also don't know which logs would be most helpful, I'll try to respond as quickly as possible to requests.
I'm having issues with my GPU on my laptop after installing Ubuntu 22.10 with the 5.19 kernel ("VM_L2_PROTECTION_FAULT_STATUS:0x00140051"). My laptop freezes after a while and I'm also not sure when or how to reproduce this because these freezes come in randomly. Apparently it's a common problem known for IdeaPad 3 laptops with AMD GPUs. One suggestion was to downgrade the kernel. Does anybody know a well-explained guide, something beginner friendly on how to downgrade the kernel from 5.19 to 5.15 without deleting the entire SSD and clean installing an LTS version of the OS?
Related to the freezes i experience, this is the error/warning I get:

Does anyone know any way to get rid of this?
I have my laptop and Two monitors. I just want to use my two monitors as two separate displays, and don't care about my laptop. Under Settings -> Displays, when I select Join Display, I would have my laptop as display1 and two monitors as display2, so I can not use two monitors as two separate displays. Any Suggestion?
I'm trying to install Ubuntu touch on a USB stick, then plug it into a windows machine and just boot Ubuntu from there.
I have downloaded Rufus and now I'm trying to find an .iso of ubuntu touch.
I downloaded the files from here but there was no .iso. I did find this post but it hasn't helped.
Where could I find the .iso?

I have been using dual boot OS one is windows 10 and another Os is Ubuntu 14.04. in windows10 ethernet working perfectly fine.but when I using ubuntu it showing ethernet cable is unplugged. I have changed the LAN wire but no use. am kind of new to ubuntu please help me? I have read similar questions here but no solution given by anyone. System Information:
Dell Vostro 3000 series; 3gb Ram 500gb hardisk
1 out of 8 times Ubuntu freezes at shutdown. When I click on Esc I see the log and it gets stuck at Reached target shutdown, but it never shuts down. I read somewhere that it's a bug and tried to follow the step of pressing Alt+Prnt screen and then typing REISUB, but nothing happened.
This question does not have anything to do with multicast DNS, multicast UPNP or anything but multicast snooping.
I know for a fact that if I do not turn off multicast snooping on my 15.10 system where the primary network interface is br0 bridge any attempt to reach an IPv6 destination will be thwarted by multicast snooping which is there to prevent flooding the network with multicast packets that most systems aren't interested. This is as simple as:
sudo sh -c "echo -n 0 > /sys/class/net/br0/bridge/multicast_snooping"You can read about it in the answer here too. There are many other sources as well.
The following manual pages are silent about multicast snooping: interfaces(5), brctl(8), bridge-utils-interfaces(5)
The man page for bridge(8) says bridge link set fastleave off is the default and the CISCO documentation for the same name (which is way better than the bridge(8) manual page IMHO) says that setting fastleave on will induce not alleviate my issue with IPv6. I haven't experimented with it yet to see if any of that is true or not.
I know that there is /etc/network/if-pre-up.d/bridge
But it says:
# You don't usually need to touch this file at all, the full configuration
# of the bridge can be done in a standard way on /etc/network/interfaces.
So is it true? Is there a way to put that in /etc/network/interfaces?
I have an ubuntu server that I access through SSH. I've changed standart port (22) to something else. I want to enable ufw on this machine. However, I'm afraid of the possibility of the following scenario occuring: as soon as I enable ufw, it'll start with default settings blocking connections and kicks me from server, especially since I'm connecting through non-standart port. Will that happen? Should I prepare some configuration first or start ufw right away? SSH is the only way of accessing my server, so loosig this due to firewall would be a disaster.
I also have some applications using some ports for UDP and TCP connections. Will these ports be automatically blocked after I enable ufw? Will I need to add exceptions for them after enabling it?
I've probably found what I wanted, but I need a confirmation from somebody.
I haven't enabled ufw yet, but I've ran some configuration commands.
First I did sudo ufw ssh
Second sudo ufw my_new_ssh_port_here
Then I had a look at /lib/ufw/user.rules
This is part of the file:
### RULES ###
### tuple ### allow any 22 0.0.0.0/0 any 0.0.0.0/0 in
-A ufw-user-input -p tcp --dport 22 -j ACCEPT
-A ufw-user-input -p udp --dport 22 -j ACCEPT
### tuple ### allow any 1111 0.0.0.0/0 any 0.0.0.0/0 in
-A ufw-user-input -p tcp --dport 1111 -j ACCEPT
-A ufw-user-input -p udp --dport 1111 -j ACCEPT
### END RULES ###
Have I set it up to allow ssh connection through my new port successfully? Is it safe to start now or do I need to configure anything else?
I'm still not sure, because sudo ufw show raw doesn't seem to show anything helpful and sudo ufw status verbose still shows Status: inactive only
How to install the Epson L350 printer step by step in Ubuntu 14.04? I am just a normal user, not a programmer.
I've just had my home internet upgraded to 50Mb/s down, but I can only get about 25 Mb/s down on my laptop over wifi. My phone gets about 45 Mb/s down over the same wifi and I get the full 50 Mb/s down when connected via Ethernet cable to the router, so I'm fairly sure the problem is on my laptop.
lspci says:
03:00.0 Network controller [0280]: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] [8086:0085] (rev 34)
This makes me think that for some reason iwlwifi isn't driving the card as hard as it can go:
mwhudson@narsil:~$ iwlist wlan0 rate wlan0 unknown bit-rate information. Current Bit Rate:54 Mb/s
(The card can do 300Mb/s according to Intel's pages, as can my router). I see similar performance on the 2.4Ghz and 5Ghz bands (my phone only does 2.4Ghz).

The previously useful ThinkWiki pages appear quite outdated. I am trying to permanently change my TrackPoint sensitivity and speed settings and enable middle mouse button scrolling. I have tried configure-trackpoint in the past, but the settings were not saved permanently (they are lost after restart).
I have tried gpointing-device-settings. Using it, I can get middle mouse button scrolling to work, but I cannot change the speed or sensitivity settings of the trackpoint. All methods on the ThinkWiki page that I've tried do not work as directed in Ubuntu 11.04. Can someone explain how to permanently edit the TrackPoint settings so that I can use it correctly?
