Description markusN 2015-08-31 12:58:06 UTC

When using fedup to update the local Fedora installation, the rpmconf tool suggested in the related Wiki page https://fedoraproject.org/wiki/FedUp#Cleaning_Up_Post_Upgrade is unclear how to define the needed merge tool.

(enhancement request migrated here from bug #990444)

What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
M : merge configuration files
Z : background this process to examine the situation
S : skip this file
The default action is to keep your current version.

ERROR:rpmconf:You did not selected any frontend for merge

Enhancement request:

Please provide a better error message. Instead of

ERROR:rpmconf:You did not selected any frontend for merge

may it be

ERROR:rpmconf:You did not selected any frontend for merge (define it with environment variable 'MERGE' or flag -f)

I am aware of "man rpmconf" - still a slightly more detailed error message would be just perfect. Thanks!

Also, the error and the manual page should suggest frontends that actually exist in the repositories.

man rpmconf:

       -ftype, --frontend=type
              Define  which frontend should be used for merging. Valid options
              are: vimdiff, gvimdiff, diffuse, kdiff3, meld.

# rpmconf -a --frontend=vimdiff
Error: vimdiff is not installed
# yum search vimdiff
Warning: No matches found for: vimdiff
No matches found

Comment 2 Miroslav Suchý 2015-09-25 14:19:47 UTC

Since rpmconf-1.0.9 those dependencies are listed as soft deps:

# rpm -q --suggests rpmconf 
diffuse
kdiff3
meld
vim-X11
vim-enhanced

Dnf search does not work unless that word is listed in summary or description, you have to use full path:
# dnf whatprovides /usr/bin/vimdiff
