Pycharm remote deployment failed after update 2525.1 "could not get host jstack"

Dear Jetbrains Support Team,

when trying to connect to remote project with Pycharm today I got the message that there is a new gateway version available, thus prompted Pycharm to install it.
However now connecting always fails in the “starting remote IDE backend” step, with the following log:

==== DIAGNOSTIC ERRORS ====

Could not get host jstack:

Details:
An error occurred while executing command: 'get-jstack --ide-path=/home/broth/.cache/JetBrains/RemoteDev/dist/97e04b93ae07a_pycharm-professional-251.23774.211 --project-path=/home/broth/oct-in-context-learning'
Exit code: 1
https://stackoverflow.com/questions/73723272/how-to-install-get-jstack-on-ubuntu

For further Information, full log at the end of the post.
In case it is relevant I got a soft warning from the server I am working on the other day, telling my my home directory used up too much space. However I since resolved that.
Researching the issue i found this post:

https://intellij-support.jetbrains.com/hc/en-us/community/posts/25075457125266-PyCharm-remote-development-not-starting
However as far as I understand I already updated to the latest remote version. I do not understand 

In case it helps, I also updated the logs archive file, you can find it under the following
Upload id: 2025_04_07_muxGidaSYpj1KmQxtkuTna (file: deploy-logs-20250407-231304.zip)
 

Thank you in advance,
Any support is gladly appreciated!

--------------------------------------------------------

Edit:

further investigation on my end revealed that the command ‘get-jstack' could not be executed on the server, due to jstack not being installed. Then on

https://stackoverflow.com/questions/73723272/how-to-install-get-jstack-on-ubuntu
I found people encountering a similar issue in regards to pycharm remote development.

The suggested solution of deleting the enire ~/.cache/Jetbrains directory and setting up an entire remote IDE backend from scratch also solved the issue for me.

I leave this here in hope it helps, as people seem to run into this issue from time to time when updating the remote IDE.

Not wanting to shift the blame from me [could have resolved this myself earlier!] I still suggest that people fixing this will have an easier time, if the error message [at the top of this post] displayed gave a hint, like

“is jstack installed on the remote server?”

in addition to “error code 1”
