Sympl 10 -> 11 — sources.list

A few days ago I asked the worst question in the history of the internet, and consequently didn’t get any answers to this issue. Mea culpa. My apologies — I’m trying again, with gratitude to those who answered other parts of my previous question.

Problem Description

I’m planning to upgrade from Sympl v10 to v11. I’m looking at the instructions here Upgrading Sympl - Sympl Wiki and when I came to the section about apt sources I noticed that I have some references to stretch still in there. My suspicion is that I should change every reference to stretch or buster to bullseye, but perhaps there are some gotchas there that I should avoid?

Is there anything there I need to take special care of? Or am I OK just to put bullseye in everywhere?

Any Error Messages

Not really errors, but where stretch shows up, and the output of apt-get update. N.B. lse is just an alias for ls that I use for convenience.

Reading package lists... Done


  • Sympl Version: 10
  • Sympl Testing Version? No
  • Debian Version: Buster
  • Hardware Type? Virtual — I think?
  • Hosted On? Bytemark

You should be fine to remove the hp-raid.list and 3ware-tools.list files, as they only refer to packages for raid hardware on Bytemark dedicated servers, and it’s unlikely they’ve had any updates.

Apart from that you should be fine, but make sure you have current backups and so on just in case.

I’m backed up the Ying-Yang, as my mother used to say: I’ve even got a script for rsyncing the latest mind-state onto my laptop, so hopefully I will never need to go anywhere near that… but when I inevitably do, it’s there.

Thanks a lot for your advice about the stretch files, that will simplify my life considerably.

Thank you!
