Hi
The X2Go Debian repository for the codename "stretch" and component "main" contained a few packages that were not meant for end-user, but internal package-building usage.
These packages have now been removed.
Please check your installation for the following packages and their binary counterparts:
┌───────────────────────┬─────────────────────────┐ │ Source Package │ Version │ ├───────────────────────┼─────────────────────────┤ │ rpm │ 4.14.2.1+dfsg1-2.0x2go1 │ │ libcomps │ 0.1.11-0x2go1 │ │ librepo │ 1.10.5-0x2go1 │ │ libsolv │ 0.6.35-3.0x2go1 │ │ gobject-introspection │ 1.50.0-1.1x2go1 │ └───────────────────────┴─────────────────────────┘
The corresponding binary packages have the same version number, so identifying them should be easy.
If any such packages are installed on your system, please remove them and reinstall the packages from your downstream distribution again.
Note: these packages did not pose a security risk. They are either backports from a newer Debian version (rebuilt for Stretch), new packages or slightly modified ones with fixes backported to the original package version. If you use them, they might be incompatible with your original data, though
Sorry for the inconvenience.
