The article provides a solution to the problem. At the end of October 2025, there was a problem with the signature of the repository repo.mysql.com, and the command `sudo apt update` displays an error: `W: An error occurred while verifying the signature. The repository is not updated and the previous index files will be used. GPG Error: http://repo.mysql.com/apt/ubuntu jammy InRelease: The following signatures are invalid: EXPKEYSIG B7B3B788A8D3785C MySQL Release Engineering mysql-build@oss.oracle.com

W: Failed to get http://repo.mysql.com/apt/ubuntu/dists/jammy/InRelease The following signatures are invalid: EXPKEYSIG B7B3B788A8D3785C MySQL Release Engineering mysql-build@oss.oracle.com

W: Some index files could not be downloaded. They were ignored or older versions were used instead.` Reason: The key has expired.[New key released](https://keyserver.ubuntu.com/pks/lookup?search=B7B3B788A8D3785C&fingerprint=on&op=index) from 10/23/2025 to 10/23/2027. Key UID: MySQL Release Engineering ### Solution 1\) Delete the old, expired key with an expiration date of October 22, 2025. If the key was added in the old way to the shared key store ``` sudo apt-key del B7B3 B788 A8D3 785C ``` If the key was added to a separate gpg file (new way): ``` cd /etc/apt/trusted.gpg.d ls *.gpg sudo rm mysql8.gpg ``` 2\) Using GPG, download the new key B7B3B788A8D3785C ``` cd ~ gpg --keyserver keyserver.ubuntu.com --recv B7B3B788A8D3785C ``` Screen output: `gpg: key B7B3B788A8D3785C: "MySQL Release Engineering mysql-build@oss.oracle.com" 2 new signatures

gpg: Total processed: 1

gpg: new signatures: 2` Let's import the gpg key in a *new way*: ``` gpg --export B7B3B788A8D3785C | sudo tee /etc/apt/trusted.gpg.d/mysql.gpg > /dev/null ``` Points 3 and 4 can be skipped if the MySQL installation has not changed. These points are provided for reference on what to do if the composition of the mysql server installation has changed.[Go to point 5](#p5). 3\) Generate a default file for mysql ``` sudo dpkg-reconfigure mysql-apt-config ``` - *MySQL and Cluster* (Currently selected: mysql-8.0) - MySQL Tools & Connectors (Currently selected:**Enabled**) - MySQL Preview Packages (Currently selected:**Disabled**). ![mysql-config1](https://ra1ahq.blog/images/5/3/2/0/1/53201df9c5b63b12ca46e975d58f10f0d24a64c5-mysql-config1.png "mysql-config1") In the mysql configurator window, press TAB to go to the lower OK button. ![mysql-config1a](https://ra1ahq.blog/images/6/f/c/5/f/6fc5f742eb10aa87bfb8044a8b0b195fa6a24d8b-mysql-config1a.png "mysql-config1a") Press Enter. On the next screen: "Which server version do you wish to receive?" Select the current version: - mysql 8.0 ![mysql-config2](https://ra1ahq.blog/images/4/6/3/8/c/4638c5cb0947507e49817968484df831ddf677bc-mysql-config2.png "mysql-config2") And press TAB to go to the bottom OK button. ![mysql-config2](https://ra1ahq.blog/images/3/c/a/0/2/3ca0251a22b3cea65bd39e38a41d6a65576b83e3-mysql-config2a.png "mysql-config2a") We returned to the previous screen... Use the cursor to move to the small line “ok”. ![mysql-config1](https://ra1ahq.blog/images/f/f/2/b/a/ff2ba7c81769bfa107ae3baa5df7370454966874-mysql-config3.png "mysql-config3") To the question: **"The file '/usr/share/keyrings/mysql-apt-config.gpg' exists. Overwrite? (y/N)"** - answer **"Y"** and key **Enter.** ![mysql-config5](https://ra1ahq.blog/images/2/d/7/9/c/2d79ced80abbea1df682ec1e8d652588fb40991f-mysql-config5.png "mysql-config5") 4\) Edit the file for the application source - a third-party repository:**mysql.list** ``` cd /etc/apt/sources.list.d/ sudo nano /etc/apt/sources.list.d/mysql.list ``` In the editor, you can press Ctrl+\\ to replace: - Search (what to change) \[signed-by=/usr/share/keyrings/mysql-apt-config.gpg\] - replace with \[signed-by=/etc/apt/trusted.gpg.d/mysql.gpg\] Replace this entry? ``` A - все. ``` Contents of the file /usr/share/keyrings/mysql-apt-config.gpg after replacement: ![mysql-config6](https://ra1ahq.blog/images/f/e/2/2/3/fe223ec6423f33098cda62e7f657cf5723ce590c-mysql-config6.png "mysql-config6") Save the file under the same name: Ctrl+O, Enter, Ctrl+X. 5\) Refresh package cache and install updates: ``` sudo apt update sudo apt upgrade ``` !!!**Comment.** I do not recommend interrupting the apt upgrade update by pressing Ctrl+C, otherwise unsatisfied dependencies will arise. Solution:`sudo apt --fix-broken install` ### Result There is no apt update error anymore, the mysql repository is signed with a valid signature B7B3B788A8D3785C. ``` gpg --list-keys ``` Key...785C expiration date: 2027-10-23 --- Sources: *[bugs.mysql.com](https://bugs.mysql.com/bug.php),* [Problem with MySQL 8.0 repository signing after 12/14/2023](https://ra1ahq.blog/en/problema-s-podpisyu-repozitoriya-mysql-8-0-posle-14-12-2023). ### Related publications [ ![](https://ra1ahq.blog/images/f/3/a/2/c/f3a2c07ef5b32c0308ab703405a5a5ca87b75283-archer-ac600-728.webp) Installing the kernel driver for the TP-Link Wi-Fi adapter after updating the Debian OS ](https://ra1ahq.blog/en/ustanovka-draivera-yadra-dlya-wi-fi-adaptera-tp-link-posle-obnovleniya-os-debian) [ ![](https://ra1ahq.blog/images/d/2/5/c/7/d25c7282750b398f71041fb8b90640b692e7e4b8-decibelfmtitle.png) Linux Cinnamon Desktop Applets for Listening to Internet Radio Stations ](https://ra1ahq.blog/en/applety-dlya-rabochego-stola-linux-cinnamon-dlya-proslushivaniya-internet-radiostancii) [ ![No picture](https://ra1ahq.blog/user/themes/mytheme/images/no-image.png) Passing a parameter to a Linux module/driver ](https://ra1ahq.blog/en/peredacha-parametra-modulyu-draiveru-linux) [ ![](https://ra1ahq.blog/images/5/c/4/e/a/5c4ea9c8c3f0b4dd890116d8fe7cbadfdb9814ba-archer-ac600.webp) Installing the TP-Link Archer T600U Nano Wi-Fi adapter driver in Debian 13 "Trixie" ](https://ra1ahq.blog/en/ustanovka-draivera-wi-fi-adaptera-tp-link-archer-t600u-nano-v-debian-13-trixie) [ ![](https://ra1ahq.blog/images/b/f/f/0/f/bff0f99f5897e0420fac9a6eef7254247f39c29d-pulseaudio-equalizer.png) Installing the audio equalizer pulseaudio-equalizer-ladspa on Linux ](https://ra1ahq.blog/en/ustanovka-v-linux-ekvalaizera-zvuka-pulseaudio-equalizer-ladspa) [ Backward](https://ra1ahq.blog/en/ustanovka-vremeni-kompyutera-s-pomoshyu-gps-na-smartfone-cherez-ssh "Previuous page") [ Forward ](https://ra1ahq.blog/en/v-chem-sushnost-fariseistva "Next page") ## Languages -
