Just checking, the cmd seems to install Kernel module algif_aead but removes module algif_aead2.   Is that correct?

Have a good day...George

You’re writing to a root-owned system file without elevated privileges.
Fix (run exactly this):
echo   "install algif_aead /bin/false"  |  sudo   tee  /etc/modprobe.d/disable-algif-aead.conf

You’re writing to a root-owned system file without elevated privileges.

Fix (run exactly this):

Then remove the module:

Also is there a space or hyphen after the word install?

Have a good day...George
