Unfortunately i don't have access to another instance of Guacamole where i can
safely downgrade to 1.5.5, but the issue about pasting was also present there
and we've only came back to Guacamole after seeing some bug fixes related to
clipboard in hope of having this issue fixed. Dont know if this info can help.
This is the output of "stty -a":

Feel free to ask anything.

> When pasting long text with multiple rows, Guacamole adds an empty line in
> between the rows breaking text formatting. This doesn't happen with
> JumpServer, so it's not browser fault.
> Tried both with Firefox and Chrome, same issue.
> For example, this curl command with multiple rows:
> curl [https://www.google.com|https://www.google.com/] \
> -X GET \
> -H "User-Agent: Mozilla/5.0" \
> -H "Accept: text/html" \
> -L
> Insted of being executed as a single command, is sent to the target as a
> command per row, resulting in the screenshot attached.
> Another example is this docker-compose,yaml file:
> services :
> guacamole:
> image: guacamole/guacamole: 1.6.0
> environment :
> - GUACAMOLE_LDAP_ENCRYPTION_METHOD: starttls
> - GUACAMOLE_LDAP_DISABLE_VERIFY: "true"
> - JAVA_OPTS: "-Djavax. net . ssl . trustStore=/path/to/cacerts -Djavax.
> net. ssl. trustStorePassword=changeit"
>
> This behaviour doesn't allow operators to smoothly work on machines,
> resulting in a turn off of guacamole in our infrastructure and look for other
> solutions.
> Feel free to ask anything if needed.

> Daniel D.
