new linux user here. I am not able to find wifi on Dell XPS 13 9343 laptop connected to internet via USB tethering. Wireless card - Broadcom BCM4352 802.11ac Dual Band (14e4:43b1) rev 03. I tried to install bcmwl-kernel-source and firmware-b43-installer but getting error unable to locate package for both commands.
Please help!
How can I play a sound when connected to the internet? I found a python script but there should be an simpler solution.
I just want to play a sound upon connection. Even notify-send would work.
I want to know when an internet connection is possible, so I do not start my browser and get a "can not find the webpage.".
My goal: install Ubuntu Desktop with full disk encryption (lvm or zfs) on an Asus NUC 14 Pro+ (Ubuntu IDs it as NUC14RVS-B with Intel Core Ultra 7 155H CPU).
What works: Installing Ubuntu without full disk encryption, using the same LiveCD and hardware.
What doesn't work: Booting up (post bootloader) after having installed full-disk encrypted Ubuntu. Screen goes black (completely, no cursor, no purple etc).
I have a LiveCD usb with ubuntu-24.04.1-desktop-amd64 (checked for correct checksum).
The LiveCD boots just fine and allows me to install (unencrypted) Ubuntu via the default settings (install third party/media codecs checked) and "erase everything" option. It finishes and boots fine after reboot.
If I do the same thing again and select the default option but only change to "advanced options" Full Disk Encryption (ZFS or LVM has same problem) the installation finishes with an OK message. After restart and remove the liveCD I am shown a boot menu with Ubuntu at the top but when I select it the screen just turns dark (but computer seems to be running still). The same thing happen if I select Ubuntu Advanced Options and boot into the Recovery Mode.
If I boot into the LiveCD again I can decrypt the drive just fine and mount it.
Gparted shows me the LiveCD has created three partitions on disk. fat32 /boot/efi (boot, esp flag), ext4 /boot and [Encrypted] on /.
The display is an Apple Studio Display connected via thunderbolt if that matters.
I have turned off SecureBoot and allowed 3rd party UEFI in the BIOS.
I have tried editing grub to boot it with nomodeset nouveau.modeset=0 i915.modeset=0 but no luck.
Any suggestions for what I should try next?
EDIT Narrowed down the issue further, it only happens when booting with the Studio Display over thunderbolt connected. Connected it to another display with HDMI and that boots up well with no issues.
After upgrading to 24.04, neither the Outline Client nor Outline Manager appimages works any more.
I did install libfuset64 as recommended in other places, but I get SUID permission errors.
$ ./Outline-Client.AppImage
[584847:1001/220953.594798:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_Outlintr1Gf9/chrome-sandbox is owned by root and has mode 4755.
[1] 584847 trace trap (core dumped) ./Outline-Client.AppImage
If I run outline with ./Outline-Client.AppImage --no-sandbox then it works perfectly fine, but this is supposed to be much less secure.
I'm wondering if there is a way to run outline without having to use the --no-sandbox flag
I want to update Linux Ubuntu 18.04 to 22.04 running on Oracle VM Virtual Box 7.0.20. Though I cannot do it in one step, I have to do it with 2, the first one should be an Update to version 20.04.
I tried it first with the software updater of the desktop. It shows me the following message:
Failed to download repository information. Check Your internet connection.
But on Firefox internet is working perfectly.
Now I tried it on the terminal with
sudo apt-get update
I get the following type of errormessages:
http://snapshot.debian.org/archive/debian-security/20140517T222731Z jessie/updates InRelease The following signatures were invalid: EXPKEYSIG 8B48AD6246925553...
and
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used...
I've already been on many sites, but I cannot find any useful hint.
Could anybody help me..?
Thanks in advance
