To restart with a new Portage database in Gentoo, you'll need to perform a few steps. Please note that this process will remove your existing Portage database and start fresh. Make sure you have backups of any important data and configurations before proceeding. Here's how you can do it:

ยง2023-09-15

$ sudo rm -r /var/db/pkg/
$ sudo emerge --emptytree @world
$ emerge --sync
$ emerge -avuDN @world

- `what is -avuDN`
    -a (or --ask): This option tells emerge to ask for confirmation before performing any actions. When you run emerge -avuDN @world, it will display a list of packages that are going to be updated, and it will prompt you to confirm whether you want to proceed with the updates.
    -v (or --verbose): The -v option makes emerge display detailed information about the package management process. It shows you the progress of the package installation or update, including compilation output if applicable.
    -u (or --update): The -u option tells emerge to update the installed packages to their latest versions. When you run emerge -avuDN @world, it will update all packages in the @world set (a set of packages that are considered essential for the system) to their latest versions.
    -D (or --deep): The -D option instructs emerge to consider not only the directly installed packages but also their dependencies. It ensures that all dependencies are also updated as necessary to maintain a consistent system state.
    -N (or --newuse): The -N option tells emerge to rebuild packages if there are changes in USE flags (compilation options) specified in the package's ebuild files. It's used to ensure that packages are compiled with the most up-

¶ 1. Backup Your Configuration:

cp -rv /etc/portage /etc/portage_backup

'/etc/portage' -> '/etc/portage_backup' '/etc/portage/profile' -> '/etc/portage_backup/profile' '/etc/portage/profile/package.use.force' -> '/etc/portage_backup/profile/package.use.force' '/etc/portage/make.conf' -> '/etc/portage_backup/make.conf' '/etc/portage/package.mask' -> '/etc/portage_backup/package.mask' '/etc/portage/package.use' -> '/etc/portage_backup/package.use' '/etc/portage/package.accept_keywords' -> '/etc/portage_backup/package.accept_keywords' '/etc/portage/make.profile' -> '/etc/portage_backup/make.profile'

¶ 2. Remove Existing Portage Database:

rm -rf /var/db/repos/gentoo


¶ 3. Reinitialize Portage:

emerge --sync

Syncing repository 'gentoo' into '/var/db/repos/gentoo'...

Starting rsync with rsync://89.238.71.6/gentoo-portage... rsync: [Receiver] safe_read failed to read 1 bytes: Connection reset by peer (104) rsync error: error in rsync protocol data stream (code 12) at io.c(282) [Receiver=3.2.7] Retrying...

Starting retry 1 of 1 with rsync://[2a00:1828:a00d:ffff::6]/gentoo-portage rsync: [Receiver] failed to connect to 2a00:1828:a00d:ffff::6 (2a00:1828:a00d:ffff::6): Network is unreachable (101) rsync error: error in socket IO (code 10) at clientserver.c(139) [Receiver=3.2.7] Retrying... !!! Exhausted addresses for rsync.gentoo.org

Action: sync for repo: gentoo, returned code = 1

Fix!!

- `(chroot) hc4Gentoo / # mkdir /etc/portage/repos.conf` 

- nano /etc/portage/repos.conf/gentoo.conf

[gentoo] location = /var/db/repos/gentoo sync-type = rsync sync-uri = rsync://rsync.namerica.gentoo.org/gentoo-portage auto-sync = yes priority = 10

- then, again

emerge --sync

...

Action: sync for repo: gentoo, returned code = 0


¶ 4. Update @world:

emerge --update --deep --newuse @world

....



> getting wrose and worse, let'start from the beginning!!!


> In summary, emerge --update --deep --newuse @world is used to upgrade and update installed packages on your system, while emerge --sync is used to refresh your local Portage tree with the latest package information from the Gentoo repository.

Reinstall Packages:
You'll need to reinstall any packages that you had previously installed. This can be done manually or by using a list of packages you had before the reset. For example, if you had a list of packages in a file called packages.txt, you can reinstall them using a loop:

bash
Copy code
while read -r package; do
    emerge "$package"
done < packages.txt
Restore Configuration:
If you made any custom configurations in /etc/portage, you can restore them from the backup created in step 1.

bash
Copy code
cp -r /etc/portage_backup/* /etc/portage/
Rebuild Configuration Files:
After restoring your configuration files, you may need to rebuild some configuration files using the etc-update tool.

bash
Copy code
etc-update
Rebuild Dependencies:
Some packages may require you to rebuild their dependencies after reinstallation. Use the following command to rebuild any missing dependencies:

bash
Copy code
revdep-rebuild
Update System:
Finally, update your system to ensure everything is up-to-date:

bash
Copy code
emerge --update --deep --newuse @world
Clean Up:
You can remove any temporary files or logs created during this process.

bash
Copy code
emerge --depclean
After completing these steps, your Gentoo system should have a fresh Portage database, and you should have reinstalled your desired packages. Please exercise caution when performing these actions, as they can have a significant impact on your system.
