I disagree with this.wizard10000 wrote:Last, *do not* use apt's dist-upgrade or full-upgrade with Testing or Sid unless you know exactly what you're doing. Plain old apt upgrade will hold back packages that aren't ready for release.
"full-upgrade" is *required* with testing/sid as it will remove packages when necessary to upgrade/install new versions with different depends/package names, which happens a lot.
If you just run standard upgrades, your system will get out of sync with "current" and there will be a growing list of "held back" packages, eventually creating an "impossible" situation.
Both methods call the apt-listbugs hooks, when installed, to warn of packages with open bugs.
