Hi!
Sorry for the newbie question, I’m totally new to openSUSE. My question is related to the third column: 1h sync, 4h sync and 24h sync - what are those? What do they mean, and why exactly these time values? What’s the benefit of the hours between each other if any?
That means the time the server has synced to openSUSE after Updates.
I assume (I never did install codecs using opi ), that they are the time elapsed since that mirror synced.
Now assuming that syncing once every 24 hours is a reasonable thing to do, they all seem to be up-to-date.
Personally I have good experience with Göttingen, but not knowing where you are based, an other one may be faster for you.
Oops, same time posts.
But we both forgot to welcome you to the openSUSE forums.
Aw, thank you very much - I’m pleased to be here. 
So if I understand it correctly, the mirrors themselves “send” an update “signal” each 1 hour or 4 hours or 24 hours, depending which one do I chose. So basically the data gets pulled/fetched down to my pc more frequently or more slowly - did I get it right? 
Sorry for this much of question, this approach is totally new to me, I’m coming from debian & arch based systems, and never seen this timed sync thingie-bingie (technical word hehe)
Basically I’m a bit confused if this 1/4/24 hour is server side’s POV “push” TO our computer, or is it a client side POV “pull” FROM the server (which then can be further customized this way).
I think you are confused. You want the codecs, which are distributed in “packages” (like all the other openSUSE software). You get those packages from a “repository”. To spread traffic, there are mirrors of the “mother” repository. In principe they should all have the same content. They get that content from the “mother”, but they do not ask the “mother” every second, but once in a certain time. The times above are to inform you when a mirror did the last time sync with the mother. Normally you should not worry about that. Only when most talk about a few hours and one about a few days or more, then I would avoid the last one.
But after you have chosen one, it will be in your repo list and it will be used every time you update. Again that will normally show no trouble, but hey, every system can go down. So it could be that after a few years it will refuse to be there. You can then either wait until repair, or go for another mirror.
You’ll note in your image that opi intends to add a Packman repo. You don’t really want to have duplicated repos. If you already have a Packman repo enabled, instead, either use zypper to install whatever you intended to have opi install, or remove the extra Packman repo if after opi gets done installing you find repo duplication.
No. It is fixed string displayed by opi. I assume it is how frequently this mirror updates it content from the master location, but the list of Packman mirrors does not explain what this time is either.
No, they have nothing to do with the “last time sync”. For a start, this is the literal string inside the opi source so it cannot reflect any real timestamp.
Thank you so much, everyone, for your answers and for putting effort into my question. I involved ChatGPT too because I couldn’t find any official documentation on this either, and I see that GPT’s answer is in sync with @arvidjaar’s statement, confirming each other:
Thank you again!!
I am happy that I started my post with “I assume …”. Assumption wrong. Thanks for the correction.
