Why a long delay after command not found?
Often when I mistype a command such as ls (e.g. I hit ENTER before I type 's') there is a long (~2s) delay after the terminal displays:
bash: l: command not found...
I can understand the reasons for a similar delay after an incorrect password is entered, per Why is there a big delay after entering a wrong password?. But why delay after an unrecognized command? Does FAIL_DELAY in /etc/login.defs affect this also?

Maybe Fedora is now also using that horrible Ubuntu misfeature that tells you "This program is not installed, to install it, type ..."? The delay is then caused by searching the database of all installable packages. Try calling psql (part of PostgreSQL), which is probably not installed by default, but is hopefully in the repositories.

after some research i have found this:
- try to uninstall the command-not-found package with
$>yum remove command-not-foundthen install it again with>$yum install command-not-found(just in case you have that package installed on your system).
if that doesn't help try:
add this to your
~/.bashrcfile:
unset command_not_found_handle

In my case it's because of some known proxy bug in /usr/libexec/pk-command-not-found
Failed to search for file: cannot update repo 'updates':
Cannot prepare internal mirrorlist:
Curl error (28): Timeout was reached for https://mirrors.fedoraproject.org/metalink?repo=updates-released-f28&arch=x86_64
[Connection timed out after 30002 milliseconds]
My proxy configuration is correct because downloading the exact same URL with a bare curl command succeeds instantly.
I checked the pk-command-not-found process does have the proxy configuration:
tr '' 'n' < /proc/$(pgrep -f pk-command-not-found)/environ | grep -i proxy
However it does not use it for some unknown reason.

In my case it's because of some known proxy bug in /usr/libexec/pk-command-not-found
Failed to search for file: cannot update repo 'updates':
Cannot prepare internal mirrorlist:
Curl error (28): Timeout was reached for https://mirrors.fedoraproject.org/metalink?repo=updates-released-f28&arch=x86_64
[Connection timed out after 30002 milliseconds]
My proxy configuration is correct because downloading the exact same URL with a bare curl command succeeds instantly.
I checked the pk-command-not-found process does have the proxy configuration:
tr '' 'n' < /proc/$(pgrep -f pk-command-not-found)/environ | grep -i proxy

Maybe Fedora is now also using that horrible Ubuntu misfeature that tells you "This program is not installed, to install it, type ..."? The delay is then caused by searching the database of all installable packages. Try calling psql (part of PostgreSQL), which is probably not installed by default, but is hopefully in the repositories.
