jest komunikat E: Pakiet firmware-realtek nie ma kandydata do instalacji

Prawidłowy sposób instalacji karty TP-Link TL-WN821N jest opisany w tym wątku https://forum.dug.net.pl/viewtopic.php?pid=318053 w poscie#11.
Tutaj sznurek https://github.com/Mange/rtl8192eu-linux-driver.
Systemowe pakiety  firmware realtek i atheros jeżeli są zainstalowane należy usunąć, mogą wywoływać konflikty sterownika.
Działa u mnie z powodzeniem, ( ver. 6.0 karty ) w Debianie 10, stery z repo nie działają. Na Ubuntu nie testowałem, ale powinny działać.
