In my linux machine, I have release-1 installed which contains a rpm foo-1.0.
foo-1.0 has obsoletes dependency with bar.
# rpm -q --obsoletes base/foo-1.0-0.x86_64.rpm
bar
Now I'm trying to update to release-2.
In release-2, foo-2.0 has removed obsoletes dependency with bar.
# rpm -q --obsoletes update/foo-2.0-0.x86_64.rpm
#
release-2 also adds new rpm bar-2.0.
The release wise updates are handled via ansible dnf module which sets update_only: false i.e it installs new packages as well as updates packages in same transaction.
For demonstration, I am using dnf command directly.
Update to release-2 rpms is failing:
# dnf --verbose install --best foo bar

Error:
Problem: cannot install both foo-2.0-0.x86_64 and foo-1.0-0.x86_64
- cannot install the best candidate for the job
(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages)
I was expecting update to work, as later version of foo which removes the obsoletes dependency is also part of same transaction.
How can this be handled? Could any dnf option or changes in dependency in rpm.spec of release-2 rpms can help?
I want foo-2.0 and bar-2.0 to be updated in a single dnf transaction.
[Edit] dnf update command cannot be used, as it will not install new packages i.e bar will not be installed. To install new package and update existing packages dnf install --best has to be used.
# dnf --verbose update --best foo bar
