Hello people, today I come to help you correct the update error of Deepin 20 1001. This problem afflicts those who did a clean installation with the ISO "deepin-desktop-community-1001-amd64.iso"published on August 25. Also, some users have reported this failure in systems that they updated from installations made with the Deepin 20 beta ISO, or from Deepin 15.
The problem manifests itself when updating from the Control Center or updating from the terminal as shown in the following images.
In the terminal the error message is identified by the following text.
Err:4 https://community-packages.deepin.com/printer eagle Release 404 Not Found [IP: 188.8.131.52 443]
The problem is caused because the developers made a mistake and misconfigured the printers repository, very useful to be able to easily install the drivers for a large number of printers from Deepin's printer manager. This error has been confirmed with the Deepin staff.
The solution is very easy, just as I like it, it is solved by copying and pasting a command, but first we are going to verify that the problem is the configuration of the printer repository. Run the following command, it is a single line, you must copy it whole.
grep -E "^deb https://community-packages.deepin.com/printer eagle non-free" /etc/apt/sources.list.d/printer.list > /dev/null && echo -e "\nLa configuración debe repararse.\n" || echo -e "\nLa configuración está bien.\n"
If the result is "The configuration needs to be repaired." then run the following command.
echo "deb http://packages.chinauos.com/printer eagle non-free" | sudo tee /etc/apt/sources.list.d/printer.list
If you manually deactivated the printer repository, you can reactivate it with the command above, or if you prefer, you can edit the configuration and replace the text with that of the following line.
deb http://packages.chinauos.com/printer eagle non-free
The next thing is to try again, to do the update from the Control Center or from the terminal.
If you have problems with very slow downloads when installing applications or updating Deepin 20, we recommend using the Deepin mirrors in Spanish, you can find the procedure you here.
We hope that with this they can correct the update error of Deepin 20 1001, but we clarify that this is not the only possible cause, if this procedure does not solve the problem, please create a new thread in the forum or ask for help in our group on TelegramThere, one of the community members can help you.
