Challenge
When attempting to update the Veeam Backup & Replication software, an error is encountered:This Veeam Backup & Replication installation cannot be updated automatically. Please contact Veeam customer support for assistance with manual update.
Cause
Veeam Backup software updates check the digital signature of several files before installing updates to ensure file integrity. All application files are signed using Global Sign certificates. Some Windows installations do not contain Global Sign's root certificates authority as trusted root certificates. This is not uncommon for systems with locked down security settings or systems with no internet access.Solution
To resolve this issue, please install the below four certificates manually on the system. If the B&R server does not have internet access, download them from another computer.https://www.digicert.com/CACerts/DigiCertAssuredIDRootCA.crt
https://secure.globalsign.com/cacert/gscodesigng2.crt - GlobalSign CodeSigning CA - G2
https://www.digicert.com/CACerts/DigiCertHighAssuranceEVRootCA.crt - DigiCert High Assurance EV Root CA
https://www.digicert.com/CACerts/DigiCertEVCodeSigningCA-SHA2.crt - DigiCert EV Code Signing CA (SHA2)
Also, please install the R1, R2, and R3 certificates from below.
