This is a problem as we have over 120 EX2300-48P in the field and at corporate.
So, I started from 15.1X53-D58.3 and using SPACE to first upgrade, automated.
Of course SPACE failed, so I decided to do it the old fashioned way and ssh to the switch.
What I saw was not enough room to complete the install. I ran cleanup, and used the following command:
request system software add /var/tmp/junos-arm-32-18.1R2.tgz force unlink no-copy
That did not work either, so lets try using a USB stick. That failed as well, so I tried it with the unlink removed via USB, and it worked.
Now, I am asking if anyone in the community is also experiencing this problem, and if you found a work around.
Thanks
