Don´t be angry, but this install link is brutal:
URL=https://www.aapanel.com/script/install_panel_en.sh && if [ -f /usr/bin/curl ];then curl -ksSO $URL ;else wget --no-check-certificate -O install_panel_en.sh $URL;fi;bash install_panel_en.sh ipssl
Try this hit all characters with other language keyboard write... Half hour fing all characters... Why is not like https://aapanel.com/install and ok?
I mean with Putty is easy, but in Proxmox VM writing is dead.
