How were the trackers added to these torrents? Assuming either a) you added them manually, or b) the tracker you downloaded the torrent files from bundled them into the torrent file?
If b), if you downloaded the torrent file again now that one of its trackers is defunct, would it still be bundled?
If no, or if a), you could remove the torrents without touching the downloaded data, then locate your “snatch list” on the private tracker (a list of all torrents you’ve downloaded), batch download them all and add them to qbt, assuming same output folder they will detect the downloaded files and go to 100% without downloading anything.
If yes, there isnt a way I can think of to remove the trackers as a batch, but aside from tidiness of your client there shouldn’t be any actual problem resulting from them being there.
Debian laptop user here, left Windows on my gaming desktop for a decent while. Now that I’m more accustomed to Linux DE’s I installed Nobara on it about a month ago. Zero issues with the NVIDIA variant on my 3080 so far
