Q: how to update debian 7.0 to newest version
A: Debian 7.0, also known as „Wheezy,“ was released in 2013 and has reached its end of life in 2018. Therefore, upgrading to the latest version of Debian is highly recommended for security reasons and to access new features and improvements.
Here are the general steps to upgrade from Debian 7.0 to the newest version (Debian 11 „Bullseye“):
- Backup your important files and data to an external device or cloud storage.
- Update the current system:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
- Edit the
sources.listfile using a text editor such asnanoorvim:
sudo nano /etc/apt/sources.list
- Replace all occurrences of „wheezy“ with „jessie“ and save the file. Then, update the package lists:
sudo apt-get update
- Upgrade to Debian 8.0 „Jessie“ by running:
sudo apt-get upgrade
sudo apt-get dist-upgrade
- Repeat the previous steps, replacing all occurrences of „jessie“ with „stretch“ and upgrade to Debian 9.0 „Stretch.“ Then repeat the same steps for upgrading to Debian 10.0 „Buster.“
- Finally, repeat the same steps, replacing all occurrences of „buster“ with „bullseye“ and upgrade to Debian 11.0 „Bullseye.“
Note that this process can take a significant amount of time, depending on the speed of your internet connection and the number of packages installed on your system. Also, make sure to read the release notes for each version of Debian before upgrading, as there may be specific instructions or issues to be aware of.
It’s also worth noting that in-place upgrades like this can sometimes encounter issues or unexpected behavior, so it’s recommended to perform a clean installation of the latest version of Debian if possible.
No a nakonec se to úspěšně podařilo!
