Suppose I had the following entries in /var/log/dnf.log:
elfutils-default-yama-scope noarch 0.185-1.el8 baseos 49 k
elfutils-devel x86_64 0.185-1.el8 baseos 86 k
elfutils-libelf x86_64 0.185-1.el8 baseos 221 k
elfutils-libelf-devel x86_64 0.185-1.el8 baseos 59 k
elfutils-libs x86_64 0.185-1.el8 baseos 292 k
emacs x86_64 1:26.1-7.el8 appstream 3.2 M
emacs-common x86_64 1:26.1-7.el8 appstream 38 M
emacs-filesystem noarch 1:26.1-7.el8 baseos 70 k
enchant2 x86_64 2.2.3-3.el8 appstream 62 k
epel-release noarch 8-11.el8 Extras 24 k
ethtool x86_64 2:5.8-7.el8 baseos 209 k
Et cetera. Then how do I deduce the remote URL the package lives at? As it happens this is an older CentOS version and my repo file referenced vault.centos.org. The box in question has since been upgraded to a recent RHEL version, so the repo files are different. Originally I thought that I could reconstruct the remote RPM URL with the above data, but it only works about 4/5 times.
