All Questions(ubuntu)

I made a sh script to mount my Synology shared folders via LFS.

It works like a charm, here's the code (xxxxx stands for the IP adress of my nas)

#!/bin/sh
#Mount the following folders on Komputer with LFS protocol:
#1. data
#2. games
#3. Youtubing
sudo mount xxxxxxxxxxxx:/volume1/data /mnt/nas_media/
sudo mount xxxxxxxxxxxx:/volume1/Games /mnt/nas_games/
sudo mount xxxxxxxxxxxx:/volume1/youtubing /mnt/youtubing/

When I run the code, the folders are mounted correctly in the mounting points in /mnt/.

I created a crontab entry with

crontab -e

and i wrote the following:

#Mount useful NAS folders when starting up:
@reboot /etc/nas_mount.sh

When I reboot the system, however, the folders are not mounted. I tried inserting a sleep 30 in my script to await for all the network services to be online, to no avail.

Any ideas?

Thanks.

I recently switched from windows to linux pls help.

Thank You

I encountered a critical system error while using OpenPanel on my Ubuntu server. After some investigation, I discovered that the current version of OpenPanel (v0.2.7) is still in the process of troubleshooting HTTPS protocol, DNS allocation, and certificate management.

The issue arose when I attempted to use these beta features. After installation, the OpenPanel website went down, and I couldn’t bring it back up using the command:

opencli admin on

I have been struggling to uninstall OpenPanel from my system. Unfortunately, the support team was not able to provide a clear solution. They mentioned that I need to manually reverse the steps in the installation bash script, which seems impractical and error-prone. (Super sad but during my troubleshooting efforts, I also faced a Docker crash error, which has further complicated the situation.)

Does anyone have a reliable method to completely uninstall OpenPanel from an Ubuntu server?

I tried below method, but didn't work.

nano fix.sh && bash fix.sh

Then pasted this content:

#!/bin/bash

After upgrading to Ubuntu 24.04 I have an issue with some picture being too dark.

Here is an example of a picture viewing it with Image Viewer and Shotwell. Shotwell is showing it properly there :

I also have the issue in firefox. The green of the top logo is right, the bottom one is too dark, whereas on other computers and before upgrading they were looking identical.

If I save the image, it look different in shotwell and image viewer :

I have an nvidia card :

» lspci | grep -i nvidia
0a:00.0 VGA compatible controller: NVIDIA Corporation GP108 [GeForce GT 1030] (rev a1)

Using proprietary driver :

» dpkg -l | grep -i nvidia-driver
ii  nvidia-driver-555                              555.58.02-0ubuntu0~gpu24.04.1                 amd64        NVIDIA driver metapackage

I know the release was delayed until Aug 29th, but its now September and I still cannot upgrade to 24.04. This is Ubuntu Server.

$ sudo do-release-upgrade -c
Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS development release
set Prompt=normal in /etc/update-manager/release-upgrades.

This is post apt update / upgrade. Even did a reboot afterwards and tried again for good measure. Was the server LTS point release delayed (not sure if its a separate release train from the Desktop release)?
