Description |
This article describes how to resolve an issue that occurs in some cases after an upgrade between major versions of FortiOS where the ISDB database may have no entries and may fail to update due to possible corruption in the package. |
Scope | FortiOS v6.0 - 6.4. |
Solution |
The following errors can be seen in updated debug when attempting an update (exec update-now):
[473] __parse_sig_data: Unrecognized digital signature.
A reboot should be attempted before trying the following. In case a reboot does not help, removing and manually updating the ISDB package may be required:
diagnose internet-service clear /data2/ffdb_app execute update-now
If the reboot or clearing of the ISDB package does not solve the issue, check the internet service database being used. If 'Full Database' is present, change it to 'Mini' by using the following command:
config system global set internet-service-database mini mini Small sized Internet Service database with very limited IP addresses. standard Medium sized Internet Service database with most IP addresses. full Full sized Internet Service database with all IP addresses. on-demand Internet Service database with customer selected IP addresses. end
exe update-now
After a successful update, revert the changes back to the 'Full' database. |
