Checking upgrade paths: Difference between revisions

Latest revision as of 11:35, 22 October 2015

To check an upgrade path works:

find a test Fedora system,
make sure none of the new packages are already installed^[1],
install part or all of the old package set,
copy the new packages to a local directory^[2],
run createrepo on this directory^[3],
point dnf to it^[4],
try a dnf upgrade.
if that fails, try to understand why, rpm -e whatever dnf upgrade installed and repeat from step 1.

You can also use:

rpm -qp --obsoletes mypackage

… to check the obsoletes declared by one of your new packages and,

dnf list obsoletes

before the dnf upgrate to check what dnf thinks about your new packages^[5].

Notes:

↑ It would confuse the tools.
↑
If you're creating them:
1. adapt the previous spec file or create a new one,
2. mock/koji-build the result.
↑
```
createrepo <directory>
```

↑ Use a repo file such as this one:

[tmp]
name=tmp
baseurl=file:///tmp/rpm
enabled=1
gpgcheck=0

↑ But that won't check scriptlets and other packaging bits so do check dnf upgrade works afterwards.
