I added a deb-src entry to my APT config matching the deb entry:
deb https://repo.dovecot.org/ce-2.3-latest/ubuntu/focal focal main
deb-src https://repo.dovecot.org/ce-2.3-latest/ubuntu/focal focal main
When this is there, I see a warning when running "apt update".
W: Skipping acquire of configured file 'main/source/Sources' as
repository 'https://repo.dovecot.org/ce-2.3-latest/ubuntu/focal focal
InRelease' does not seem to provide it (sources.list entry misspelt?)
Were source packages excluded deliberately? The github repo for dovecot
does not have a "debian" directory, which is the other route that would
allow me to build packages.
Thanks,
Shawn
