Reading package lists… Error! E: Unable to parse package file /var/lib/apt/lists/raspbian.raspberrypi.com_raspbian_dists_trixie_main_binary-armhf_Packages (1) W: You may want to run apt-get update to correct these problems E: The package cache file is corrupted

/var/lib/apt/lists/ 里的缓存文件坏了
删掉缓存 → 重新生成 就能解决

按顺序执行（照抄即可）

停止 apt 相关进程（以防万一）

sudo killall apt apt-get 2>/dev/null

删除损坏的缓存文件（关键步骤）

sudo rm -rf /var/lib/apt/lists/*

放心删，只是缓存，不是已安装的软件

重新生成缓存

sudo apt-get clean
sudo apt-get update

这里不应该再报 Unable to parse package file
