Description of my issue

i did a mistake and tried to install ssmtp. in the installation process, Debian uninstall a lot of yunohost packages. I think I’ve been able to recover all the packages that i removed by looking at /var/log/apt/term.log.

the list of packages:

i tried to reinstall the packages but even after that, i couldn’t access the admin page (403 forbidden error) at local ip, and in the domain page i couldn’t log in.

next i tried to run this command

curl https://install.yunohost.org | bash

but it fails. the log: https://paste.yunohost.org/raw/iridokodah

i even tried to restore by the yunohost.backup, but it also failed

    key_info["size"] = info["size_details"][category][name]
TypeError: list indices must be integers, not str

please help me to recover the server.

Hopefully that kind of stuff shouldn’t happen anymore in 3.6.x as YunoHost will now be flagged as “essential” and it will be much complicated to remove it by mistake :stuck_out_tongue_winking_eye:

Anyway : if you reinstalled the packages (it sounds like you did), try to :

touch /etc/yunohost/installed

The thing about yunohost backup sounds like a real bug in yunohost though, would be interesting to see what’s the content of the corresponding backup_file.json (in /home/yunohost.backup/archives/). But in any case the fix with the touch should work I think.

after i run this command:
touch /etc/yunohost/installed

what i should do?
i tried to run again this command:

curl https://install.yunohost.org | bash

and got:

Your configuration files for :     
- postfix                               
- dovecot

- metronome                                         
will be overwritten !

Just go to your admin interface and yunohost should be back without the need to do the postinstall…
