Ubuntu 22.04 LTS无法运行Appimage解决方法：

首先sudo gedit /etc/apt/sources.list 更换为阿里源（记得备份）

内容如下：

deb http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse

保存后执行：

sudo apt-get update

然后：

sudo apt install fuse libfuse2
sudo modprobe fuse
sudo groupadd fuse
user="$(whoami)"
sudo usermod -a -G fuse $user

之后chmod 777 + 你的Appimage之后再运行Appimage就ok了！
