Description dbpalan 2015-05-07 03:59:05 UTC 
SFTP connection failed with OpenSSH server 6.7 or above found from Debian 8 / Ubuntu 15.04.

This is suspected due to lack of supported encryption algorithm compiled in the IDE module com-jcraft-jsch.jar

More information can be found from: https://sourceforge.net/p/jsch/bugs/79/

Comment 1 dbpalan 2015-05-07 05:34:15 UTC 
This is an update of the bug:

System upgraded from 8.0 -> 8.0.2 will suffer from this bug since ide\modules\com-jcraft-jsch.jar would not be upgraded, the file size is 224,310 bytes.

System newly install 8.0.2 will NOT suffer from this bug, file size of the jar file is 226666 bytes.
Comment 2 LadyCailin 2015-05-15 20:17:41 UTC 
I am suffering from this same bug.
Comment 3 Tomas Mysik 2015-05-29 09:28:51 UTC 
So, if I understand it correctly, we need to wait for new version of JSCh (the JSCh issue is still opened) - am I right? Feel free to let us know once it is released.

Thanks.

I installed netbeans 8.0.2 separately, but ide\modules\com-jcraft-jsch.jar  the file size is 224,310 bytes i.e. it is the same as 8.0, where to get file 
226666 bytes size?
Comment 5 miraged 2015-06-06 09:02:31 UTC 
Update: you have to export all settings and keyrink passwords (if you need) and do clean uninstall of upgraded version, then do clean install of netbeans 8.0.2 and import previously exported settings
Comment 6 Tomas Mysik 2015-08-24 06:31:46 UTC 
Could anyone please confirm that this issue is resolved with the latest Jsch (0.1.53)?

Thanks.
Comment 7 Tomas Mysik 2015-08-27 09:24:20 UTC 
JSch upgraded to the latest stable version [1], so closing this issue. Feel free to reopen but please provide information what can be done on NetBeans' side.

Thanks.
