![mysql-workbench-community 无法通过 ssh 连接](https://linux22.com/image/1186787/mysql-workbench-community%20%E6%97%A0%E6%B3%95%E9%80%9A%E8%BF%87%20ssh%20%E8%BF%9E%E6%8E%A5.png)
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!
