[SOLVED] Can't upgrade kernel after downgrading

I was doing a kernel upgrade the other day which was interrupted when arch froze up. Wasn't able to boot into gnome after that. One of the graphical services (plank) was having trouble pulling the distro version. I tried downgrading back to 4.18.16 which seemed to work, and tried performing the upgrade again.

The upgrade succeeded, but after rebooting, I still had issues. Except this time, I lost my broadcom-wl driver and couldn't connect to the internet. uname also tells me that 4.18.16 is still loaded. Not sure what I can try doing at this point. Any thoughts?

Your /boot was not mounted during the upgrade. From a chroot, make sure /boot is mounted and upgrade linux.

I'm pretty sure /boot is mounted?

$ ls /boot/
initramfs-linux-fallback.img initframfs-linux-lts-fallback.img vmlinuz-linux ...

You may be pretty sure, but that command and output says nothing of the sort.  lsblk, mount, or findmnt could be useful for checking.

Re: [SOLVED] Can't upgrade kernel after downgrading

Ah, yeah. I guess that's misleading since the upgrade command writes to that directory regardless whether or not it's mounted. Followed jasonwryan's advice, mounted /boot from the live USB, chrooted into root, and upgraded the kernel. Everything seems to be working now. Thanks!
