[bennohef]

What happened?

Deluge 2.1.1 with libtorrent v1.2 do not start. Seems some installation issue with deluged package (libtorrent).

Installation do not fail, but deluged just do not starts.

This is happening on Debian 12, within 11 there are no issues.

I have the same issue. #1146

I have the same issue. #1146

Fixed it. Just change boost lib. version. By default it's 1.74, change to latest one on today (1.85).

It can be changed in "/etc/swizzin/sources/functions/libtorrent", there you will find "BOOST_VERSION" variable in boostrap function.

Oh wow. Yeah that was it. Works on my end now also :). Thank You

When you do this and recompile with : sudo box upgrade deluge

It overwrites those changes as it repulls the swizzin repo. How do you make it use the new boost version?

Edit: create .dev.lock file and it won't overwrite. Thanks.
