Hi all,
I have a package that contains a subdirectory which is changed to a
symlink in the next release. When I upgrade, I get the following error:
Error: Transaction check error:
file /usr/share/symlinktest/dir/subdir from install of
symlinktest-1-2.fc25.x86_64 conflicts with file from package
symlinktest-1-1.fc25.x86_64
The first version (1-1) of the spec file contains:
mkdir -p \
%{buildroot}/%{_datadir}/%{name}/dir/subdir
ln -s \
%{_datadir}/%{name}/testfile %{buildroot}/%{_datadir}/%{name}/dir/subdir
which is changed in 1-2 to:
mkdir -p \
%{buildroot}/%{_datadir}/%{name}/dir/
ln -s \
%{_datadir}/%{name}/testfile %{buildroot}/%{_datadir}/%{name}/dir/subdir
As you can see, in the second case, the subdir is not created anymore,
and thus %{_datadir}/%{name}/dir becomes a symlink to
%{_datadir}/%{name}/testfile. In other words, instead of having the
symlink in dir/subdir, dir/subdir is now a symlink itself.
I'm not sure what to make out of this. How can a file conflict with a
file of the same package (but previous version)? Is this a dnf issue?
Removing the old version and then installing the new version works fine.
I've attached both versions of the spec file. You can also find them on
pagure: https://pagure.io/symlinktest
Any hints are welcome.
Thanks,
Till
