Sudo apt update is failing. It says:

E: Could not get lock /var/lib/apt/lists/lock. It is held by process 1408 (packagekitd)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to lock directory /var/lib/apt/lists/

ps aux | grep ‘[a]pt’ gives me:

root 1023 0.0 0.2 134896 9436 ? Ssl 11:56 0:00 /usr/sbin/thermald --systemd --dbus-enable --adaptive

adaptive is highlighted, specifically the apt part.

If it’s safe to remove, i’m planning on using:

sudo rm /var/lib/apt/lists/lock
