Problems Upgrading
You upgrade and you get the following message
Verified manifest signed by PackageProductionECP256_2020 method ECDSA256+SHA256
Hardware Database regeneration succeeded
Validating against /config/juniper.conf.gz
mgd: commit complete
Validation succeeded
Validating against /config/rescue.conf.gz
/config/rescue.conf.gz:75:(21) syntax error at ‘rfc-complaint’
[edit system phone-home]
‘rfc-complaint;’
syntax error
Validation failed
ERROR: Configuration validation failed with /altroot/cf/packages/install-tmp/junos-20.4R1.12
Note the “Validating against /config/rescue.conf.gz”
This indicates the rescue configuration will not play nicely with the new version of Junos. To fix/update the rescue configuration, make sure the current configuration does not have the item indicated in it (in this case we would “delete system phone-home”) save that configuration, then to re-create the rescue configuration
request system autorecovery state save
Then you can upgrade Junos
