Bug 25135

Created attachment 11188 [details]
return of the command LC_ALL=C urpmi --replacefiles --auto-update --auto --download-all --test > migration-en_627.txt

Thats because you use "--download-all" wich makes it download every rpm locally before install...

But I see the confusion... the size number is incremental, so it's the last line:

compiler-rt-8.0.0-1.mga7.x86_64 needs 8852MB on the / filesystem

that tells you how much space it needs in the end...

It could maybe be improved...

yes, but the option --download-all is indicated in the upgrade guide of the mageia site: see 
https://wiki.mageia.org/en/Mageia_7_Release_Notes#Upgrading_from_Mageia_6

furthermore, in the file migration-en_627.txt, line 142 says:
"installation fails"  why?

(cat -n migration-en_627.txt displays the lines number)

It states "It is *sometimes* a good idea to ...", basically meaning especially with unstable internet connection, you might be better of downloading all first...

Because with all stuff downloaded, you dont have enough free space on / anymore.
It tries to protect you from not trying to install something that will fail due to running out of disk space

Reassigning to Docteam. The "It is sometimes a good idea to test the upgrade before carrying it on." message could maybe be changed into:

"It is sometimes a good idea, when you have more than enough free disk space, to test the upgrade before carrying it on."

Or in anything better that Docteam thinks of :-)

Summary: nonsense huge free space needed for migration mageia6 to mageia7 => It would be nice if the Release notes would suggest to make sure a user has enough free space, before using "--download-all"
Severity: normal => enhancement
