I have a very dated VM that works as a mail forwarder for my organization, it is a Ubuntu Server VM running 20.04 LTS which connects to google workspaces and sends email for our on prem devices such as copiers, software, scripts, etc. I went to run some security updates using apt-get and I got an interesting error saying that there is a 401 Error Unauthorized IP.
The fix is to disable the sources in the sources.list directory, which I have two files.
- ubuntu-esm-infra.list
- ubuntu-esm-infra.list.distUpgrade
In VI I commented out the source lines.
reinstalled apt
After I was able to update the system; and upgrade the outdated packages. Now I can go headed and upgrade the system to the newer release.
