If anyone having this same problem finds their way here, this is the script to upgrade to Haveno Retoswap v. 1.1.0. Run it in regular Terminal, not Root Terminal right next to amnesia@amnesia:~$
It takes about 10 min to install and the Terminal looks like it's frozen during the install but it's not. Here's the script:
curl -fsSLO https://raw.githubusercontent.com/XMRZombie/haveno/refs/heads/tails/scripts/install_tails/haveno-install.sh && bash haveno-install.sh https://github.com/retoaccess1/haveno-reto/releases/download/1.1.0/haveno-v1.1.0-linux-x86_64-installer.deb DAA24D878B8D36C90120A897CA02DAC12DAE2D0F
