I am setting up my first VM with debian (x64) and kali linux... I am a windows user but want to learn linux. while upgrading linux using sudo apt upgrade I got a message like this.

translated with https://translate.yandex.com

But I do not really understand what it means. If someone could help me I will be very pleased. (I am a very begginer in Linux)

*Disclaimer: If you do not understand the picture, in resume it says that PostgreSQL 14 is not working more, and I must upgrade to postgresql-15 and postgresql-client-15 and upgrade it clusters with order "pg_upgradecluster"

    Hi! Let me stop you there! Learning Linux is great, but it should not be done using Kali Linux, say not only I and all experienced Linux users I've personally talked to, but also Kali Linux themselves: https://www.kali.org/docs/introduction/should-i-use-kali-linux/#:~:text=The%20fact%20of%20the%20matter,general%2Dpurpose%20Linux%20desktop%20distribution – Marcus Müller Nov 02 '22 at 06:35

    But, the thing is, it is not clear what you mean when you say "with Debian and Kali", because while Kali is based on debian in a way, it is a separate thing with its own special rules and methods. One of the rules is "this is not a Linux that you should use for everyday work, so we don't care if updates break things, or goal is solely to be the right toolkit for a Linux expert with a different Linux somewhere else when they go on a penetration testing excursion, so, boot Kali, penetrate, save data, forget about the stick you've booted from,next time get the newest Kali and put it on a stick" – Marcus Müller Nov 02 '22 at 06:40

    I’d recommend two edits: 1) removed the photo and translate it to English as text in a quote block. 2) clarify whether you are using Debian or kali. – James Risner Nov 02 '22 at 15:05

The picture says that PostgreSQL 14 is not working more, and I must upgrade to postgresql-15 and postgresql-client-15 and upgrade it clusters with order pg_upgradecluster:

The PostgreSQL 14 version is deprecated, but the PostgreSQL package client or server are still installed. You must install the latest versions of the packages (postgresql-15 and postgresql-client-15) and update your clusters with the command pg_upgradecluster (see the man page).

Note that installing postgresql-15 will create automatically a default cluster 15/main. You have to delete the existing cluster 15 (pg_dropcluster --stop 15) if you want to update the 14/main cluster, see the man page for the details. The old client and server packages are no longer supported. You should remove the packages postgresql-14 and postgresql-client-14 after upgrading any clusters you have. For more information see /usr/share/doc/postgresql-common/README.Debian.gz

If you didn't use postgres so far, just click "accept" and continue your upgrade.

Upgrade your postgreSQL Database from 14 to 15 on Debian

see Upgrade your postgreSQL Database from 14 to 15 on Debian

Or you dump and re-import your data with

sudo -u postgres pg_dumpall --cluster 14/main > ~/backup_postgres_all_dbs.tar
sudo -u postgres psql -d postgres --cluster 15/main -f ~/backup_postgres_all_dbs.tar
