我在通过 ssh tunel 连接到 mysql 服务器时遇到问题，应用程序崩溃了。
我已经在 snap 权限对话框中启用了 ssh-keys，但这似乎没有帮助。
每次我尝试使用 ssh 连接时，都会出现“无法连接到 SSH 隧道，主机的真实性......”弹出窗口，在我确认（例如确定）后，再次尝试连接并崩溃。
工作台是否可能无法将 ssh 指纹添加到某处（因为它总是再次询问）？
我设置了另一个连接，为此我需要手动打开似乎可以正常工作的 ssh tunel。（但如果没有 ssh tunel，工作台仍然会崩溃）。
刚刚安装了全新的 22.04 Ubuntu
MySQL Workbench 8.0.25 内部版本 788958。
MySQL 服务器：8.0.28（在 AWS 上，服务器似乎没有参与？）
snap 的 Strace 看起来很有趣，也证实了我的理论。在打开 known_hosts 进行读取，然后写入（都失败了？）后，它立即崩溃了：
[pid 102272] close(16) = 0
[pid 102272] openat(AT_FDCWD, "/home/letynsoft/.ssh/known_hosts", O_RDONLY) = -1 ENOENT (No such file or directory)

我如何启用此快照来访问.ssh/known_hosts？
任何帮助都值得感激！
