#308 Can't connect to ssh server, Ubuntu 18.04, PAC-VS v4.5.5.8

[Viet Nghia Nguyen]

I can't connect to this server, ssh from terminal is ok. I'm using private key for authentication, please help!
Here's the debug log:

When I use ssh from terminal:

[nghianv@dev-docker-10-5-20-36 ~]$ 

[Abhishek]

try changing the private key location in connection option
In my case pac was using private key present at snap/pac-vs/common/ssh location

Let me know if you find any alternate solution

[Viet Nghia Nguyen]

My pac-vs default private key localtion is my home directory, which is normal.
There was an update for some perl libraries, and after that my pac can't connect to any ssh server.
My perl version is now 5.26.

When I run pac-vs from terminal:

nghianv@Acer-Nitro:~$ pac-vs
PAC started (pac) with PID 16414
INFO: Used config file '/home/nghianv/snap/pac-vs/common/.config/pac/pac.nfreeze'

(pac:16414): GLib-GIO-WARNING **: Error creating IO channel for /proc/mounts: Permission denied (g-file-error-quark, 2)
INFO: Using 'Unity' tray icon

The only solution I have found is move to asbru-cm. It's a fork of pac, run smoothly, and I can import all my connections from pac to it.

I had the same problem, i could't connect to ssh server, Ubuntu 18.04, PAC-VS v4.5.5.8.

I solved it, adding to /home/youruser/snap/pac-vs/common/ssh/config the following lines:

Host <host_you_are_trying_to_connect>
HostkeyAlgorithms +ssh-dss</host_you_are_trying_to_connect>

[jrussell88]

Neither of these solutions got pac-vs working for me under Ubuntu 20.04.02 LTS, so I installed the forked version of Pac Manager, asbru-cm which worked without any further issues.
