Error while installing mailutils

[YoKoNo]

Hi Craig,

Following the latest install video for Magento 2.

However when installing the new mailer server - I get this error:

Errors were encountered while processing:
 postfix
E: Sub-process /usr/bin/dpkg returned an error code (1)

Googling doesn’t appear to help at this time.

Any suggestions?

Thanks

Paul

@YoKoNo

Sub-process /usr/bin/dpkg returned an error code (1)

I did apt upgrade after apt update and this resolved the issue

also during the install of sample data I had another issue with elastic search

“could not validate a connection to elasticsearch. no alive nodes found in your cluster”

which was solved by “sudo systemctl restart elasticsearch”
