Alien failing to convert .rpm to .deb (18.04)

I’ve used this command before and it’s worked fine so this may have to do with the file I’m trying to convert but when I run alien on this .rpm I get this error:

mkdir -/debian failed: No such file or directory at /usr/share/perl5/Alien/Package/Deb.pm line 373. 

No .deb is created but some folders with names like opt/ and etc/ are created in the same directory as the .rpm, I tried just copying their contents to the respective system folders but that didn’t work, guess its not that easy.

This is what I’m trying to install:

Wireless Woes: iwlwifi-8265 – Ubuntu 18.04 (and Mint Tara)

I am trying to set up two machines, both have identical hardware that should be supported by the newer Linux kernels. The wireless card inside is a GIGABYTE “GC-WB867D-I” Wifi+Bluetooth. Out of the box the Bluetooth works, however the Wifi does not.


The kerenel version via: uname -r

5.0.0-31-generic

The firmware version via: modinfo iwlwifi | grep 8265

firmware: iwlwifi-8265-36.ucode

The firmware file code via: lsmod | grep iwlwifi

iwlwifi 315392 1 iwlmvm

The Network controller via: sudo lspci | grep Network

41:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)


The more verbose Network controller via ID: sudo lspci -vnd 8086:24fd

What I have tried…


Replace the iwlwifi-8265-22.ucode file in /lib/firmware/ folder with the drivers from Intel. The folder contains, iwlwifi-8265 (-21), (-22), (-27), (-31), (-34), (-36) for newer kerenls I’d assume.


Changed the power settings via gedit, wifi.powersave = 3 (3) -> (2) -> (1) in file/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf


Updated, upgraded, updated kernels etc… I am usually okay at troubleshooting linux issues, however this one has me stumped. I noticed the firmware version points to iwlwifi-8265-36.ucode, while the Intel driver points to iwlwifi-8265-22.ucode. Is this the issue?


I have lost a day to this problem, and normally I can solve these issues somewhat quickly. With any luck I can solve the issue within the next day, else I will buy two new PCI cards :<. Any help is greatly appreciated, thanks!

Ubuntu 18.04 not working with Panda Wireless PAU09 on USB 3.0

Recently received a Panda Wireless PAU09. It works fine on any of the computer’s USB 2.0 ports, but not USB 3.0 ports. USB 3.0 ports are functional, as they can connect to other USB devices.

lsusb shows the device in the list:

Bus 008 Device 000: ID 148f:5572 Ralink Technology, Corp. RT5572 Wireless Adapter

However, lshw -C network shows only the ethernet interface.

The device works fine on a USB 3.0 port on Windows 10.

Screen Brightness wont change Ubuntu 18.04 Intel

Cant change the brightness with keys or through the bar on the top right.

ive changed my /usr/X11/xorg.conf.d/FILEHERE multiple times with different given solutions and each one breaks my computer to command line only.

Ive made changes to my /etc/default/grub to include/change

GRUB_CMDLINE_LINUX_DEFAULT="quite splash"  

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor" 
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=video" 

And even tried adding a backlight file (to which i get a not allowed error even running in sudo), on.

/sys/class/backlight 

but since I am not allowed i am all that is in my /sys/class is

Bug al iniciar DHCP en Ubuntu Desktop 18.04 / Bug when starting dhcp in Ubuntu 18.04

soy estudiante de Administración en Sistemas Informáticos en Red (ASIR). Estoy realizando la actividad para configurar el servidor dhcp en Ubuntu 18.04. Al comprobar su estado me resalta un mensaje diciendo que tengo un bug.

Hi. Im a computer student. I have to do an activity to set up a dhcp server on Ubuntu 18.04. When I check it condition, in the terminal appears a message say that I have a bug.
