Accidentally deleted cfg80211 Ubuntu 22.04 Kernel version 5.15.0-43-generic
While trying to install some adapter drivers as shown here, I accidentally deleted my
/lib/modules/5.15.0-43-generic/kernel/net/wireless/ directory completely where
cfg80211.ko is stored, and I would like to repair it if possible.
I’ve tried running
sudo apt-get install --reinstall linux-image-5.15.0-43-generic and similar combinations but that simply gives me
Reinstallation of linux-image-5.15.0-43-generic is not possible, since it cannot be downloaded.
You sadly can’t easily reinstall old kernel versions. Is there anything that’s holding you on 5.15.0-43?
If not, just run
sudo apt install linux-generic which should give you the most current one (5.15.0-83 on my machine) and reboot.
