I am attempting to upload an mp4 file (112MB) to a Linux server. After a successful transfer, its size is reduced to 103MB or 80MB. It is not uploading the full size. Its Owner/Group changed automatically into root/root as well. If I stop the lsyncd service, the transfer completes without any issue with size stays intact.
We cannot stop the lsyncd service as there is replication going on for all the files in that directory across multiple file paths in different network locations. I reviewed the lsyncd logs but found nothing.
Can anybody help me out? I also checked lsyncd logs, but no issue was found. I checked the transfer mode in FileZilla, and its set to Auto mode.
I tried changing the transfer mode to Binary from auto. I also checked the lsyncd config file, everything looks fine. Also, we can't stop the lsyncd service every time we upload as there are lots of files to be transferred. This issue started to happen recently.
Hi all,I have a MSI GE75 Raider laptop with an Nvidia 2070 and Intel processor. My screen broke a while ago. I have been using the laptop with an external monitor through HDMI, which was fine until I accidentally broke the graphics drivers on Windows. Now Windows loads but no image is shown on the external monitor. I can tell that Windows loads because of the welcoming sound. BIOS also does not show on the monitor, although I can tell that I can get to BIOS blind: when I key bash Del at startup, then press F10 (to save and exit) followed by enter, the laptop reboots as expected.
I have been able to boot from USBs, but only by removing the SSD, so the bootloader only has the USB as an option. I haven't been able to find a combination of keystrokes that takes me to the boot menu, even though I have seen videos of it and it should be easy.
The only way I got an image on the HDMI screen is with the ubuntu Live USB. I created it with ubuntu-22.04.3-desktop-amd64.iso and Balena Etcher. I get to see the loading screen, and then logs that end in [FAILED] Failed to start Ubuntu live CD installer, and then the screen starts blinking every 0.5 seconds. Could it be because of the lack of SSD? The logs are here: https://imgur.com/a/rb3cwEC https://imgur.com/a/f0yTMRl
I would like to use this Installer to create a partition and install Linux, so I can use the PC again. How could I get pass this error? I know that there are options on the Ubuntu initial boot menu, and I would be happy to try them, but I would need the exact keystrokes because at that stage, I can't see anything.
I tried the first and second choices of the boot loader - on the first I get the error. On the second one, that I believe is with Safe Graphics, the HDMI screen does not turn on. I selected it by pressing arrow down and enter.
I can also try other versions of Ubuntu or other distros if you think I can be luckier with them.
I'm devastated about this to be honest, and I can't afford a replacement screen at the moment. Any help is great and welcome.

I'm running ubuntu server on my raspberry pi, and I can SSH it when im connected to the same network that the RPi is on. However, I can't SSH into it when I'm on a different network, even after opening port 22 (TCP/UDP) through router settings. Any ideas?
Wasn't this suppose to be released today? Just curious.
I saw a video showing off all of the cool features of the newest Gnome version, and I realized that I am currently on version 42.9
I know that it is so low because I chose the LTS version on set up but I was new to Linux (I still am to a certain degree). Thus I was wondering if there is a way to directly upgrade to the new version?
I'm trying to automate the setup of industrial equipment running ubuntu 22.04. Each device has a monitor attached but no keyboard/mouse and I'd like to automate it with bash regardless. Upon computer startup, the activity overview pops up, shrinking our application at customer sites without any way to click the app. After some research, I've found two ways to disable this:
I've tried number 1 but it isn't working. While
➜ ~ gsettings list-recursively | grep "org.gnome.shell.extensions.dash-to-dock disable" org.gnome.shell.extensions.dash-to-dock disable-overview-on-startup true
the overview still pops up upon starting.
I can't seem to figure out how I can download and install the gnome package through bash. I do not want to be forced to manually install it on every machine we construct and ship out to customers. Plus, I'd like to make changes to deployed equipment and I can only do this through ssh.
Recently I noticed that my power usage is quit high (nvidia-smi). When idling it is ~ 90 W. When I compare that to the windows idle (50 W) that is twice the usage in idle.
Now I checked the nvidia control panel thingy, it says it should regulate automatically, but that doesn't seem to be the case. Anyone else had this problem?

I am following the guide for a manual install of Landscape from here. I have the certs installed. When I restart apache2, it throws this error:
Sep 21 11:32:53 server.com apachectl: AH00526: Syntax error on line 57 of /etc/apache2/sites-enabled/landscape.conf:

I have build a few before and not received this error. This server Ubuntu 20.04. Greatful for any suggestions.
I know that initd days are gone but I am slightly confused as to what is going on with the three from the subject: Netplan, networkd and networkmanager. Netplan is an abstraction layer for fancy YAMAL-styled config I understand. Now, why (or maybe I have not researched this long enough) there is no clear distinction between when to use networkd and when to use NetworkManager?
My understanding was that NetworkManager belongs to the desktop way of managing network connectivity and networkd is predominantly designed for server use.
Now, I installed fresh 20.04 and am getting NetworkManager running my network layer.
Can someone please shed some lite as to how to even think about these components and what is their main purpose and natural habitat? Surely, this is not OK for all those living and randomly managing network devices on a host (I am a server user so this is where my focus is as opposed to Desktop).

Running a VM of Ubuntu 22.04.3 LTS. I just encountered systemd-networkd-wait-online.service failed. Not sure how or why this happened as it's been running fine up until now. Anyone know how to fix this?

I was having issues with high-dpi my laptop display and wayland. In order to fix the bluriness of the discord desktop application, I changed the .desktop file with the following entry:
Exec=/usr/share/discord/Discord --enable-features=UseOzonePlatform,WaylandWindowDecorations --ozone-platform=wayland
This solved the issue, but now I cannot close/minimize and drag the application, since the top bar has disappeared.
Can I fix in some ways this newer issue?
PS: I've also tried with the following option, but nothing changed:
so I download Vm, dowload Ubuntu ISO, boot it all up, as this is my second time making a linux VM. but apparently I cannot use sudo, and in order to use sudo, i need a user that has sudo access. how the hell am i supposed to get sudo access. sudo -i dont work. add user needs root access to add user to sudoer file. whoever made this stupid rule to where in order to to anything on this stupid OS you need another account to give you root access. what a fucking stupid OS rule.
if anyone knows how to fix this please tell me cuz google is absolutely fucking useless for this stuff.
Recently installed ubuntu and assigned around half a terabyte of storage for it because I'm still dual-booting windows. It's been one day since I've been using Ubuntu and I already only have 24GB left.
My = is getting pressed automaticall so I want to do it. Watched some tutorial
one of them said to type
xinput float 5
This disbaled both keyboard and enabled both keyboard
Another video asked to download a github code and runned the command said in video but didn't worked
What should I do?
Also after connecting external keyboard the problem has solved 90% automatically how?
I'm not sure what's going on but, the Volume control will go up and down by itself all the time. It doesn't matter if I'm on YouTube or playing a game through Emulation. Or so on. Pulse audio didn't fix anything and it still does it. It's an HDMI to HDMI ( Tv to my PC). I've tried to reboot the PC a few times and that doesn't fix it either. Does anyone have any suggestions?
You might ask, WHY?!?! Cuz I had an extra SSD and a drive bay and wanted to run Ubuntu INSIDE windows. After MUCH trial and error, here's how to do it.
Now you can run Ubuntu INSIDE windows, drag and drop to and from each, copy/paste, and everything you do will be saved to the drive.
So when you have multiple pages open in Chrome, it's easy to pull a bit "down" and that one tab becomes a separate window.
Now, since I'm a windows user, I'm used to this, I just grab the little tab and pull it back into the main window, and that's it, they're "merged".
But in Ubuntu, whenever I hold and grab the little tab, the mouse snaps to the top of the actual window, so they can not be merged.
Am I doing something wrong?
Clearly I don't understand what I should, but whatever. I happened to be reading /var/log/auth_log on a Vultr VPS running Ubuntu 22.04 x64. I did not realize that the default install included a user called "ubuntu" with a UID of 1000. I thought I'd been hacked but now I am not sure because I spun up another fresh VPS of 22.04 and, sure enough, it included the user "ubuntu".
Sshd is set to use certificate auth, no password auth. The exposed port is whitelisted by the firewall to only one IP. (Yes, I know, not perfect.)
But I saw a login from tty01, I presume the novnc console... here's a screen shot of what happened to better explain it. I am a newb, and when I originally deployed this vps I named it "login", so thats why the auth log says login so many times. It's my dumb hostname. But please, look at the photo, tell me what went on here? After seeing this, I changed user "ubuntu"' default shell to /usr/sbin/nologin
screenshot of /var/log/auth.log
I see the cron:sessions and they don't puzzle me, but the September 18 22:59:59 login 902 session for ubuntu? This also appears with the "last" command, and there is no ip address.
Can someone explain this?

Pidgin doesn't work anymore since I upgraded from 22.10 to 23.04 today. I get the following error when I try to open it in Terminal:
*** stack smashing detected ***: terminated
Aborted (core dumped)
If I try to open it from the launcher it doesn't open and I get no error at all. Any suggestions on how to fix the problem? I apparently have version 2.14.12 installed.

When installing Ubuntu (most recent LTS version) it always seems to get stuck at the updates and software page after hitting next. Same issue when installing Linux Mint, any flavour, or debian.
System is an 11 inch MacBook Air (late 2015).
Anyone had similar issues when installing any variation of Linux and have a solution? Lete know if there's any more info that could be helpful.
Hi. IdeaPad 5 Pro running Ubuntu 2022 LTS doesn't turn power off: just at some moment rotating "in progress" indicator disappears and that's all. I'm forced to use power button.
The issue doesn't depend on the way "shut down" command was initiated: via DE (Gnome or KDE) mouse clicking, or via "sudo poweroff", or "sudo reboot" - results are the same.
The notebook previously was running under another Linux distro (Arch based), and it was free from the problem.
Probably some newer kernel is needed, but I not aware of official Ubuntu way to play with kernels (especially on LTS edition) yet.
Here is the link and if you want the gimp file I can host it somewhere. I know it's not a tech question exactly but thought r/ubuntu would hopefully appreciate these.
I have gotten an external SSD that I want to use Linux on. I tried install Kubuntu on it the "normal" way like it was just another partition on my laptop. This did not go well. I could log into the newly made Kubuntu external SSD, but my old system was not bootable any longer. A grub error came up.
Also the external SSD was unable to boot on any other computer..
I have found several online tutorials on how to install it without encryption, but sadly that is a must as it will handle sensitive patient data.
Anyone who can point me to a good tutorial for this, or knows how to do it?
i keep getting error message when i am using Ubuntu 22.04 is not responding .i don't know what happen i recently reinstall my Ubuntu .can you please tell me how to stop it the frequency of message are 3 to 4 times a day
I host virtualbox with Ubuntu and all of the "cookbooks" online seem to assume I'm hosting with Windows when they explain how to share a vpn installed on the host with the vm guests. I have the host only adapter installed in virtualboxand the vpn adapter appears in the host whenever the vpn is in use, but it doesn't seem to be sharing it with any of the vms. Does anybody know what I'm missing?
Hi, I've been searching quite a lot on this subject and I'm not sure if there's an official support for Ubuntu on the NanoPi R6C. I'd like to know if it's possible to easily install Ubuntu on this device please.
