Note

If you get errors from the above command, the upstream repo has a different name than what you defined in our .repo file. Visit the OBS repository to find the correct name and add it to the .repo file.

Replace old release string with release variable

$ sudo sed -i 's/15.4/\$releasever/g' /etc/zypp/repos.d/*

@oleksis Thanks for the update. 👍

Sorry to bother you again, but I think there is still some aspect missing. 😇 For example, some people could still have a "15.3" string in the base URL. Even if you use the --releasever option this won't have any effect on these URLs.

I'd suggest to add an additional section:

## Replace old release string with release variable

    sudo sed -i 's/15.4/\$releasever/g' /etc/zypp/repos.d/*

It could be added before section "Refresh all repositories to 15.4". The reason for this is, this approach isn't completely fool-proof, unfortunately. 😢 I run myself into some issues before.

If the upstream repo can be found or not depends highly on how the upstream repo maintainer has defined its name. For example, if a repo has in the base URL something like openSUSE_Leap_15.3 and you replace "15.3" with $releasever there is no guarantee that the name openSUSE_Leap_15.4 exists. The repo maintainers could name it 15.4. Some repos did that. OBS doesn't provide stable and consistent names, it's pure convention.

Therefor it would be helpful to give the reader in section "Refresh all repositories to 15.4" a hint. Maybe something like this:

If you get errors from the above command, the upstream repo has a different name than what you defined in our `.repo` file.
Open your browser and visit the OBS repository to find the correct name and add it to the  `.repo` file.

@tomschr Thanks for the feedback . Add the Note 📝
