Ubuntu Linux

MariaDB's new AppArmor profile is now enforcing in Debian unstable and heading to Ubuntu 26.04. If you are a dba/sysadmin, check your logs and share feedback via the Debian bug tracker.

I am in the very strange situation, since I installed Ubuntu, in which my laptop is connecting to the wifi, but if I open the wifi settings page it stays on "searching for networks" forever. Since I am planning to use this laptop at a conference where I would need a connection, I would like to solve this somehow.

I have used the "wireless-info" tool and the pastebin can be found here .

Only things I noticed are the Intel AX201 controller that in other forums is said to not work at all (not my case), and the fact that my home network connection is defined by a networkd yaml, as opposed to the others (my parent's house) that are defined by a NetworkManager yaml.

I am a beginner so these are all just guesses from me.

Is there a fix or even a separate software I can use to manage my connections, like adding a new one without having to write myself a new yaml file?

I've been running Ubuntu 26.04 'Resolute Raccoon' on my 'Streaming Fortress' PC
NUC7 - Intel J5005 - 16GB DDR4-2400 RAM - 120GB SSD (2013 Hardware)
for the last two months now.

I put this machine through the wringer: heavy streaming on a bit ambiguous shady sites films and tv series, and running custom 'Fortress' scripts to isolate it completely from my home network.

Despite the hardware being a bit old and the heavy workload, it’s been a flawless experience so far. Even the major updates didn't break my custom scripts or security structure. Well done, Ubuntu team!! 🐧 🫶

I often need to allow some randomly selected port to be open (tcp & udp) in the Uncomplicated Firewall (UFW), while some app is active. Then I'd like to close it. The port number is written in a file, say portfile

At the moment I'm doing this manually: read the number, then call sudo ufw allow xxxx/tcp in a terminal. Later on, delete the port rule with sudo ufw delete [rulenumber].

I'm trying to write a bash script to do this in a more automated way. It's easy to read the number from the flie as a variable, then call ufw with that number (provided the script is started as sudo).

What's not clear to me is how to delete the UFW rule once the application is closed. I could start the app within the bash script itself. Maybe it'd just be a matter of waiting for it to finish?

I'm very thankful for suggestions and ideas – and learning more about bash tricks :)

I just got this

$ sudo apt update && sudo apt -y install timeshift
Henter:15 https://www.synaptics.com/sites/default/files/Ubuntu stable InRelease [9.626 B]
E: Repository 'https://www.synaptics.com/sites/default/files/Ubuntu stable InRelease' changed its 'Origin' value from '' to 'Synaptics Inc'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.

What fresh hell is this?

I used it the first time because i am a circuit designer this is truly a blessing

just run: sudo apt update && sudo apt upgrade to fix the issue.

I've used multiple linux distro's in the early 2000's but found myself going back to macOS for the last 15 years.

Recently my macbook pro crashed and I decided to ditch big tech and bought a refurbished Lenovo X1 Carbon gen 8 (i5, 16 GB ram, 256 GB disk) for 300 euros (without VAT) & installed Ubuntu 24 LTS

I must say I am so surprised with how polished the OS feels, the fingerprint reader, the screenshots, emojis, the battery life of my Bluetooth headphones, hibernating correctly, pluging in a printer that just works ... its in the little things ...

It has really become something that I can hand over to my mom now and be confident that she will not bump into one issue after the other. Hats of to all devs involved that made this happen!

Two weekends ago I upgraded my Ubuntu desktop from 22.04 to 24.04.3 and was left with an unusable system because I opted to keep my existing copy of the gdm-smartcard-pkcs11-exclusive configuration file because I don't use a smartcard.

But it's a new configuration file and is REQUIRED. By saying I didn't want it updated, the update program didn't create the new one. And since there wasn't an old one, the upgrade failed with "error: alternative path /etc/pam.d/gdm-smartcard-pkcs11-exclusive doesn’t exist" and "The upgrade has aborted. Your system could be in an unusable state." Oh, it certainly was.

It might as well have said, "Enter N if you want your system to become unusable."

The upgrade program should never have asked. If the file is required and it isn't there, it should have just created it. I think it's a bug in the update program.

gdm3, ubuntu-desktop, and ubuntu-desktop-minimal weren't installed. PAM was not set up. No way to log in.

I wrote a blog post about how I recovered from this in case anyone else is bitten by this same issue: https://jerry.hear-me.blog/ubuntu-22-04-to-24-04-upgrade-failure-missing-file/

From another article referenced there:

The maintainers of the Ubuntu Linux distribution are now rewriting GNU Coreutils in Rust. Instead of using the GPLv3 license, which is designed to make sure that the freedoms and rights of the user of the program are preserved and always respected over everything else, the new version is going to be released using the very permissible or "permissive" (non-reciprocal) MIT license, which allows creating proprietary closed-source forks of the program.

There will surely be small incompatibilities - either intentional or accidental - between the Rust rewrite of coreutils and the GNU/C version. If the Rust version becomes popular - and it probably will, if Ubuntu starts using it - the Rust people will start pushing their own versions of higher level programs that are only compatible with the Rust version of coreutils. They will most probably also spam commits to already existing programs making them incompatible with the GNU/C version of coreutils. That way either everyone will be forced into using the MIT-licensed Rust version of coreutils, or the Linux userland becomes even more broken than it already is because now we have again two incompatible sets of runtime functions that conflict with one another. Either way, both outcomes benefit the corporations that produce proprietary software.

(Source – which does contain some more-than-problematic language outside of these passages, compare the valid objections raised by others in the cross-posts.)

Compare also how leaders of Canonical/Ubuntu have ties to Microsoft, and how the Canonical employee who leads the push to rewrite coreutils as non-GPL-licensed Rust software has spent years working for the British Army, where he "Architected and built multiple high-end bespoke Electronic Surveillance capabilities", by his own proud admission.

Hey, I am forced to use Ubuntu 20.04 because it's the only distro and version currently supported by Shadow, which I use for several hours every day. (Yeah, it sucks that they haven't kept up with updates or support other distros...) And I'm trying to install Floorp browser but I get errors both via apt get install and via flatpak. Here are the two errors:

apt get install floorp
floorp : Depends: libgdk-pixbuf-2.0-0 (>= 2.22.0) but it is not installable
E: Unable to correct problems, you have held broken packages.

flatpak install flathub one.ablaze.floorp
Looking for matches…
error: Unable to load summary from remote flathub: URI https://dl.flathub.org/repo/summary exceeded maximum size of 10485760 bytes

I'm pretty new to Linux so I have no idea what to do here. I found nothing helpful when searching these errors.

Please don't lecture me how this is not a good idea. The system is non critical with zero important data, I just need least effort to input and confirm password.

During install, Ubuntu 25.04 allowed me to type in 1 character long password, but I picked the wrong key that's not as convenient as I thought.

I've tried changing password and GUI won't allow me to do it and passwd complains about length and still makes it look like it changes it, but doesn't really. So, how can I bloody do it without reinstalling the whole damn OS again because only installer isn't complaining about it?

Thanks

I am new to Ubuntu and Linux, so I will almost certainly not have enough information, sorry.

I set up my two monitors with the refresh rate, location, and placements and saved and it all worked fine.

The machine went to sleep, and when I woke it up, it had defaulted the display settings.

I have had a look around, and someone suggested setting the displays through the Nvidia x server app, but that still did the same thing.

Has anyone had this or know a solution? Its not a huge deal, but it is a pain to reset them everytime I log on.

Hello,

Before the current ubuntu upgrade, i used a proprietary driver, but now, the command "ubuntu-drivers devices" return an empty result. I'm tempted tu use the ppa, but i fear it could break my system.
