dpkg-deb: error: 'graylog-4.3-repository_latest.deb' is not a debian format archive

3. What steps have you already taken to try and solve the problem?

Researched error. verified I can download the deb file from site.

4. How can the community help?
I think Graylog need to update the repository

Hello && Welcome

That command is incorrect. It needs to be like this.

sudo dpkg -i graylog-4.3-repository_latest.deb

Sorry That was my typo.

I do have

sudo dpkg -i graylog-4.3-repository_latest.deb

I just tested the documentation here out to ensure it was working. Using Ubuntu 20.0.4

I executed both of these.

root # wget
root # sudo dpkg -i graylog-4.3-repository_latest.deb


I would double check your commands, perhaps some log files may help.

Where is the log during the install.

Otherwise ill grab screenshots wheni get home and follow up tomorrow


Linux I would look in /var/log directory. Probably in dpkg file.

As for this error…

error: 'graylog-4.3-repository_latest.deb' is not a debian format archive

I would clean my repo up and try to download it again.

EDIT: did some googling and 90% of the error “is not a debian format archive” either has to do with the network and the package got corrupt OR the naming convention of the package.
Like I menetion above try clean your repo and re-download the package again OR rename the package without using "-"

root # cp graylog-4.3-repository_latest.deb  graylog_4.3_repository_latest.deb

As for Graylog repo I don’t see anything wrong.

well I don’t see what is different today, but it all appears to be working. Thank you for the assistance!
