This web page shows some downsides I found in software packages. Each of them, on their own, can cause major troubles to newbies trying to use the software. For more experienced people they spoil the fun using the software and often cause headaches. Some issues may exist by incident, some may be caused by policy of the software author. As soon as an issue is gone to my knowledge, it will be striked out from this website. Known workarounds will be listed too, as long as they are required.

Doesn't properly support ftps:// (Debian jessie)

Trying to use TLS to connect to proftpd <1.3.5a can cause extensive delays during directory switches. Unstable Debian stretch (proftpd 1.3.5b-3) resolves this, though there is no backport to stable Debian jessie (proftpd 1.3.5-1.1+deb8u1), rendering proftpd useless for most users of stable secure servers. »After upgrading from Debian jessie»Debian stretch, which is now marked as the stable release, the issue has been resolved.
