Could the problem be linked to the language configuration?

22

postgresql is already the newest version (9.6+181+deb9u2).

It look like you didn’t really purge postgresql. If you don’t firstly purge postgresql it won’t be possible to install it cleanly.

23

Same problem.
According to the log, the reason comes from the fact I didn’t uninstall postgresql properly.

Here is what I did:

apt-get --purge remove postgresql\*
rm -r /etc/postgresql/
rm -r /etc/postgresql-common/
rm -r /var/lib/postgresql/
userdel -r postgres
groupdel postgres

For the 2 last lines, the users were not found and I don’t know how to check what else it could be.
Also, I still have this message asking to check my language settings.
Here is the detail of these commands:

Ok now,

Could you try sudo -u postgres psql ?

25 
root@thibaut:~# sudo -u postgres psql
sudo: unknown user: postgres

26

Hi Thibaut,
did you solve your postgres problem finally?

27

Hi Rocky,
Still not.
Despite re-installing the OS from scratch, I keep having the same problem.

It looks like I solved the language error by making that “locale” gets the same language for all the lines.

Now, the current error log is the following one:
