[tde-users] Problem installing Trinity in Debian

Hello, I bought a new laptop for my brother and I've installed Debian 11.7 on it (with the default Gnome DE), but when (installing from USB stick) I try to select a mirror to download packages I get this: | Jun 1 09:50:59 choose-mirror[31078]: WARNING **: mirror does not support the specified release (bullseye) This has happened with both http://deb.debian.org/ and http://ftp.us.debian.org/ (!) I also tried installing without using a mirror for additional packages, but then apt-get doesn't work because of missing configuration files. Help! :-) Leslie -- Platform: Linux Distribution: openSUSE Leap 15.4 (x86_64) Desktop Environment: Trinity Qt: 3.5.0 TDE: R14.1.0 tde-config: 1.0
