Junos OS

Hello all,

I'm trying to upgrade a Juniper MX204 to the suggested J-TAC software release 18.2R3-S3.

I have downloaded the software from the Juniper website (junos-vmhost-install-usb-mx-x86-64-18.2R3-S3.11.img.gz) and uploaded it to my MX204 in /var/tmp/usb

The software checksum seems fine:

admin@router> file checksum md5 /var/tmp/usb/junos-vmhost-install-usb-mx-x86-64-18.2R3-S3.11.img.gz

MD5 (/var/tmp/usb/junos-vmhost-install-usb-mx-x86-64-18.2R3-S3.11.img.gz) = 10046234ff6bcac521070942f0b30da6

But I keep getting an error when installing:

admin@router> request vmhost software add /var/tmp/usb/junos-vmhost-install-usb-mx-x86-64-18.2R3-S3.11.img.gz

Junos Validation begin. Procedure will take few minutes.

Also unzipping doesn't help:

Any suggestions?

Hello roelp,

please note that if you want to upgrade the JUNOS by CLI, you need the following image:

Install Package --> VMHost 64-Bit  ==  junos-vmhost-install-mx-x86-64-18.2R3-S3.11.tgz

Then you can install the image by performing "request vmhost software add /var/tmp/junos-vmhost-install-mx-x86-64-18.2R3-S3.11.tgz"

The command "request system software add" is deprecated on NG-RE platforms (like MX204), please don't use this command at all.

The file "junos-vmhost-install-usb-mx-x86-64-18.2R3-S3.11.img.gz" you have downloaded is an "Install Media" file, which is only for performing a recovery installation with an USB device attached, if the JUNOS installation is corrupted and the device does not boot anymore.
