I am interested in lines 125 to 130. Please run:

history | less

and capture all those lines

get out of 'less' with q

scroll with the arrow keys

xtrchessreal

I can't capture all at once aprox 250 lines

chili555

Just lines 125 to 130, please

6 lines

xtrchessreal

125 sudo m-a prepare
126 sudo ./dkms-install.sh
127 sudo apt remove rtl8821ce-dkms
128 sudo apt install bc module-assistant build-essential dkms
129 sudo m-a prepare
130 sudo ./dkms-install.sh

chili555

115 to 124, please. I need to see what directory you were in when you did this

so we can undo it!

xtrchessreal

114 sudo apt install bc module-assistant build-essential dkms
115 sudo m-a prepare
116 sudo ./dkms-install.sh
117 reboot
118 sudo apt install bc module-assistant build-essential dkms
119 sudo apt autoremove
120 sudo apt install bc module-assistant build-essential dkms
121 sudo m-a prepare
122 sudo ./dkms-install.sh
123 sudo apt remove rtl8821ce-dkms && sudo apt install rtl8821ce-dkms
124 sudo apt install bc module-assistant build-essential dkms

Let's try a different way:

xtrchessreal

I was in Downloads/rtl8821ce

from terminal

chili555

Ah!

cd /Downloads/rtl8821ce && ls`

xtrchessreal

x@x-HP:~/Downloads/rtl8821ce$ ls
clean dkms-install.sh hal Kconfig platform wlan0dhcp
COPYING dkms-remove.sh halmac.mk Makefile README.md
core Dockerfile ifcfg-wlan0 os_dep rtl8821c.mk
dkms.conf get_sources.sh include PKGBUILD runwpa

chili555

sudo ./dkms-remove.sh

errors? warnings? sparks? smoke? just kidding!

xtrchessreal

sudo ./dkms-remove.sh
[sudo] password for x:

great! Now how about:

sudo dkms status

xtrchessreal

sudo dkms status

thats all

chili555

wonderful

now:

sudo dpkg -s rtl8821ce-dkms | grep Status

xtrchessreal

sudo dpkg -s rtl8821ce-dkms | grep Status
[sudo] password for x:
dpkg-query: package 'rtl8821ce-dkms' is not installed and no information is available
Use dpkg --info (= dpkg-deb --info) to examine archive files.

chili555

excellent

xtrchessreal

yay

chili555

00:17

now a more or less final check:

sudo updatedb

takes a few moments and returns blank

hopefully

xtrchessreal

without b right

sudo updatedb
sudo: updatedb: command not found

chili555

just a moment...

sudo apt install -y mlocate

then try:

sudo updatedb

xtrchessreal

just goes to cursor, no return

chili555

locate -i 8821ce.ko

xtrchessreal

locate -i 8821ce.ko
/usr/lib/modules/5.13.0-37-generic/kernel/drivers/net/wireless/realtek/rtw88/rtw88_8821ce.ko

chili555

00:24

ls /usr/src | grep 8821

xtrchessreal

no return

chili555

I think you are all set. I will edit my answer to give a brief description of what we did. If it is helpful, I hope you will accept it.

xtrchessreal

I'm sure I will, no need to check for conflicts first?

chili555

didn't we already? Let's be sure, though:

xtrchessreal

Don't breathe on it!

xtrchessreal

chili555

00:32

Anthing a new user can wreck I think and I hope I can polish up and get running again.

xtrchessreal

Okay I'll wait for your edits in the answer and I might need to add something in my question or remove something

chili555
