I might be wrong but downgrade could also ask to put thinks in the ignore list. in pacman.conf, think if that so to mention it. if in the future want to upgrade again :)

Thanks, very interesting.   :D

I thought that the ARM was closed (and it was true in August 2013), but I'm happy that it's open again.

Me either until today. It & other similar scripts have actually been around for quite some time it would seem! I've neglected them as using pacman -U has been fine by me. But if you don't have the package in your cache, using Downgrade just makes it SO quick & easy to get yourself an earlier version.

As soon as I saw Downgrade mentioned on the forum, I had to check it out & then make a wiki page (& this support thread) for it. It is just so cool that the Manjaro community must know about it.  8)

That is a good point ringo.

I just had a look at the man downgrade page & it says the following:

Quote
IGNORING PACKAGES
       As it is common to add a package to the IgnorePkg directive in one’s pacman configuration
       after downgrading, downgrade offers to do this for you automatically.

       The process is skipped if the package name is already present in IgnorePkg.

I obviously had better add information relating to this to the wiki page.

Thanks ringo. :)

Only a little warning : if the cache is cleaned, it will take the Arch release of a package, not the Manjaro one. And if both differ...  ;)

That is another important point Esclapion.

Life is so complicated...

I don't know how Downgrade works (I'm not a dev) so I don't know how complex & how much work it would be;- I wonder if Downgrade could be modified to work on packages from the Manjaro repos & the AUR?

I modified the wiki re. the Arch/Manjaro package problem:

But the Manjaro repos dont contain the preceeding releases of a package.

For that, we need a MRM (Manjaro Rollback Machine), lol :)

Hi,

thanks posting and the reminder.

Nowadays, after installing the downgrade, one is asked
Code: [Select]
add (name of downgraded package) to IgnorePkg? [y/n]
If answered with y, it will be written to
Code: [Select]
/etc/pacman.conf
Best Wishes
