That is a good idea, thank you – will check on unattended-upgrades situation – as well as alternate mirrors – then update post accordingly.
but the way the shell installer script was adding the ‘stable’ repo is really close to one of the official EXAMPLES offered in the man page:
add-apt-repository -S 'deb http://myserver/path/to/repo stable main'
vs. shell installer:
add-apt-repository -y -S "deb $DEBIAN_MIRROR stable main non-free non-free-firmware" >> "$log"
Maybe. With a -y added to force it – instead of prompting the user. Maybe. (It is likely that the sysadmin module update will take a similar approach using native Debian apt management commands.)
Not yet officially, no. We’ve made some mostly cosmetic updates to the FreePBX Versions schedule released earlier this year, but to answer this part of the question, FreePBX 17 will remain on Debian 12, while FreePBX 18 will be developed on Debian 13 with official work beginning on 2026-04-01 and a current estimated beta release date of 2026-09-01.
Good point, thank you.
There’s some variability there in the file name, depending on your environment and what the DEBIAN_MIRROR variable looked like during shell script execution.
Another helpful command to consider:
$ apt-add-repository -L | grep stable
…that’s the thing to check if you are going to have a problem or not – empty output there is a good sign (unless unattended-upgrades is overly aggressive with changing repo lines, but IDK if that it is the case – assuming it is not.)
