Hi Jonas, I made a couple of tests on my machine, where the med-bio metapackage is installed. ‘apt-get -o APT::Install-Suggests=true install t-coffee’ installs t-coffee-doc and t-coffee-examples, which is expected as the other suggested packages are recommended by med-bio. If I install an unrelated package with aptitude, it removes t-coffee-doc and t-coffee-examples. I then purged t-coffee, and tried to install it with aptitude, with the command ‘aptitude -o APT::Install-Suggests=true install t-coffee’, but aptitude seems to ignore APT::Install-Suggests=true. This shows that we may not be able to work with aptitude. Later, I realised another and bigger problem: APT::Install-Suggests=true has a recursive effect. Ran in a minimal system, ‘apt-get -o APT::Install-Suggests=true install t-coffee’ tried to pull an enormous number of packages. APT::Install-Suggests=true therefore can give very different results according on which system it is used, which is I think a killer problem in our case.
