Thanks for your help.
It seems to works fine now

If you installed Stable branch and it completed successfully you should be on 1.5.10.1673, not 1.5.10

Did it complete successfully?

Can you try the curl you see it erroring out and see what you see?

It seems like maybe you’re behind a proxy? or something, I don’t know. If this were broken in general, i’m certain we’d have known about it by now.

curl --silent -kOL https://github.com/FOGProject/fos/releases/latest/download/init.xz

• Could not download init.xz properly

I replace lastlog by lastlog2

So you need to stash the changes or revert those changes.

This can be done in many different ways, usually the simplest method being:
git checkout lib/common/functions.sh but this would only fix this one file, if you’ve any others you changed manually, then you may need to do any/all of those files.

The stash method is another simple way to move all custom changes out of the way:

git stash then the steps.

I don’t know what changes you were making so this is entirely up to you on what steps you’re willing to part with. Have a backup handy of your installation directory just in case.

I’ve got an error :

git checkout stable
erreur : Vos modifications locales aux fichiers suivants seraient écrasées par l'extraction :
        lib/common/functions.sh
Veuillez valider ou remiser vos modifications avant de basculer de branche.
Abandon

git checkout stable
error: Your local changes to the following files would be overwritten by the checkout:
        lib/common/functions.sh
Please commit or stash your changes before switching branches.
Abandon

git branch
 dev-branch
* master

cd /path/to/fog-project/installer/folder
git checkout stable
git pull
cd bin
./installfog.sh

That should be all that’s necessary. The stable can then be changed to master for 1.5.10 official release, and dev-branch for whatever the bleeding edge of FOG is based on the 1.5.10 branches. and working-1.6 to see the beta version.

git clone https://github.com/FOGProject/fogproject.git /home/fog-depot
cd /home/fog-depot
git branch
git checkout master or git checkout dev-branch
git init
git pull
cd bin/
./installfog.sh

Thanks for your help

What could be the solution to this problem?

I don’t know if it will work or not.

We had one person try it, and I just got around to adding what they suggested as found here:
https://github.com/FOGProject/fogproject/pull/733

I think it will work just fine, but we won’t know for sure until someone tries. What works for one may or may not work for another, so your mileage may vary.

Starting with a fresh install would perhaps be easier.
