I was wondering if anyone could offer some clarity on how best to
apply patches on Debian derived systems? There are so many options
across apt-get and aptitude... I cannot make sense of them all:
apt-get upgrade
apt-get dist-upgrade
apt-get safe-upgrade
aptitude upgrade
aptitude safe-upgrade
aptitude full-upgrade
aptitude is a front-end to the APT. apt(-get) dist-upgrade
"intelligently" manages dependencies, e.g. from recent update
on Sid: libpng12-dev was replaced by libpng-dev; with simple
apt upgrade libpng12-dev would be kept, but with dist-upgrade
it is being replaced.
"apt safe-upgrade" doesn't exist, only "aptitude safe-upgrade";
the first is comparable to
"aptitude --no-new-installs safe-upgrade".
In other words, "aptitude safe-upgrade" upgrades and can install
new packages, but never removes anything; "apt upgrade" never
installs or removes unmet dependencies; "aptitude full-upgrade"
is similar to "apt dist-upgrade".
Cheers,
Mitt
