How to go back previous version installation as my new version is not working correctly

2

@hereabdulla, use bench drop-site site1.local to remove your actual site, and run

bench switch-to-master
bench new-site site1.local --install-app erpnext

Edit: dont forgot that do you need be in frappe-bench folder to run this!

3

I have already site1.local is running when I drop it what about the data

4

I update to v7 but I cant assign role to user when I am saving it did u know any solution for this

5

@hereabdulla, the solution is wait a bit, since in the weekend, is not common for the people work in the world! (but have exceptions), the guys will fix it soon!

6

If you have data, so, was a bad idea try to upgrade without have the announcement of the ERPNext v7 ready!

Currently, the things can break! And system managers should know it! :slight_smile:

7

I am only updated to v6.27.19

8

@hereabdulla, so you can return using git!

go to the frappe and erpnext folders and run

git revert -bytag "v6.27.19"

and

bench migrate

in frappe-bench folder!

to get a complete list of releases

usage: git revert [options] <commit-ish>...
   or: git revert <subcommand>

    --quit                end revert or cherry-pick sequence
    --continue            resume revert or cherry-pick sequence
    --abort               cancel revert or cherry-pick sequence
    -n, --no-commit       don't automatically commit
    -e, --edit            edit the commit message
    -s, --signoff         add Signed-off-by:
    -m, --mainline <n>    parent number
    --rerere-autoupdate   update the index with reused conflict resolution if possible
    --strategy <strategy>
                          merge strategy
    -X, --strategy-option <option>
                          option for merge strategy

@hereabdulla, sorry for my mistake!

git reset --hard "v6.27.18"

Due, 6.27.18 is the previous version!

@hereabdulla, backups never are a bad choice!

@hereabdulla, so, the version that do you updated, introduce a change, that is not easy to reverse! The best choice, is upgrade again, and wait to the fix!

Or maybe do you can make the fix, and open a pull request, to get it ASAP!
