Dependency error with nginx 1.22.0 on Debian 10 (buster)

[mbautista]

Hello @darylounet Thank you for this awesome repository :) I have a dependency problem trying to install libnginx-mod-brotli on Debian 10 buster. nginx version is 1.22.0 installed from nginx official repo. libnginx-mod-pagespeed from your other repo works well :) Do you have any idea how I could solve this ? Thank you very much for your help :) Mathieu.

Hi @mbautista This is strange, as official NGiNX repository has removed Buster support since 1.24.0. Can you paste here the result of apt-cache policy nginx please ?

Hello @darylounet You will find the output below. So I guess the solution is to upgrade to Debian 11 ? Thank you for your help :)

Sorry I looked too fast last night, I was tired... You're using libnginx-mod-pagespeed, which is deprecated and no longer builds with NGiNX 1.24.0. So if you want to keep pagespeed module, you have to stick with NGiNX 1.22.0, you should freeze the package with apt-mark hold. Then you can download and dpkg -i the brotli module with this exact version (and remove the packagecloud repository).

Thank you very much for your help ! I will try your solution for 1.22. What a pity ngx_pagespeed is abandoned, we host hundreds of websites using this module... On the other hand we can't stop upgrading nginx, so sooner or later we will have to drop ngx_pagespeed. Thanks to you, I have a little time to search for an alternative so thank you very much again :) Mathieu.
