Package: synaptic Version: 0.83+b1 Severity: normal --- Please enter the report below this line. ---
I switched from unstable/experimental to testing by editing /etc/apt/sources list and doing an apt-get update. Now synaptic crashes on startup with error message: E: The value 'unstable' is invalid for APT::Default-Release as such a release is not available in the sources E: _cache->open() failed, please report. --- System information. --- Architecture: amd64 Kernel: Linux 3.11-1-amd64 Debian Release: stretch/sid 500 testing ftp.de.debian.org --- Package information. --- Depends (Version) | Installed =========================================-+-================== libapt-inst1.5 (>= 0.8.16~exp12) | libapt-pkg4.12 (>= 0.9.11) | libatk1.0-0 (>= 1.12.4) | 2.10.0-2 libc6 (>= 2.14) | libcairo-gobject2 (>= 1.10.0) | libcairo2 (>= 1.2.4) | libept1.4.12 | libgcc1 (>= 1:4.1.1) | libgdk-pixbuf2.0-0 (>= 2.22.0) | libglib2.0-0 (>= 2.14.0) | libgtk-3-0 (>= 3.0.0) | libpango-1.0-0 (>= 1.14.0) | libpangocairo-1.0-0 (>= 1.14.0) | libstdc++6 (>= 4.6) | libvte-2.90-9 (>= 1:0.27.2) | libx11-6 | libxapian22 | libxext6 | zlib1g (>= 1:1.1.4) | hicolor-icon-theme | Recommends (Version) | Installed ==============================-+-============= gksu | 2.0.2-6 OR kdebase-bin | OR policykit-1 | 0.105-3 libgtk2-perl (>= 1:1.130) | 2:1.248-1 rarian-compat | 0.8.1-5 Suggests (Version) | Installed ======================================-+-=========== dwww | menu | 2.1.46 deborphan | apt-xapian-index | 0.45 tasksel | software-properties-gtk |
