Upgrading Plesk Panel from 9.5.2 to 9.5.3

[webphibian]

From Plesk, I tried upgrading from 9.5.2 to 9.5.3. The upgrade failed with the following warnings/error:

How should I proceed? Thanks in advance.

make sure that you have the ability to write that file, immutable may be set.

lsattr /usr/bin/ssh

should return
------------- /usr/bin/ssh

if you see anything else, remove immutable.

chattr -i /usr/bin/ssh

Then try again.
