Uninstall Denied?

[PienChan]

I tried the commands in uninstall.sh but konsole says "Permission denied"

(deck@steamdeck ~)$ systemctl stop tailscaled
systemctl disable tailscaled
rm /etc/systemd/system/tailscaled.service
rm /etc/default/tailscaled
rm /etc/profile.d/tailscale.sh
rm /etc/atomic-update.conf.d/tailscale.conf
rm -rf /opt/tailscale/tailscale
rm: remove write-protected regular file '/etc/systemd/system/tailscaled.service'? 
rm: remove write-protected regular file '/etc/default/tailscaled'? 
rm: remove write-protected regular file '/etc/profile.d/tailscale.sh'? 
rm: remove write-protected regular file '/etc/atomic-update.conf.d/tailscale.conf'? 
rm: cannot remove '/opt/tailscale/tailscale': Permission denied

What do I do?
