deb-src entries in sources.list are not updated from xenial to bionic

[John George]

After an upgrade from 16.04 to 18.04 deb-src entries in /etc/apt/sources.list are still set to xenial rather than bionic.

These lines are commented out by default so it's not an issue until the source repo is enabled. For instance a script that automates enabling source repositories may just uncomment the line, however in this case additional logic would need to be added to also update the release name.

How did you go about upgrading from Ubuntu 16.04 to Ubuntu 18.04?

[John George (jog)]

The upgrade was triggered with:
    sudo do-release-upgrade -d

Also attached the console upgrade log.

The log file /var/log/dist-upgrade/main.log would be useful as that contains information about the modification of sources.list e.g.:

2018-04-25 20:01:35,151 DEBUG examining: 'deb-src http://dell.archive.canonical.com/updates/ xenial-dell public'
2018-04-25 20:01:35,152 DEBUG entry '# deb-src http://dell.archive.canonical.com/updates/ xenial-dell public # disabled on upgrade to bionic' was disabled (unknown
