Internal case CPANEL-7836 is open to address an issue where /var/cpanel/autossl_queue_cpanel.json is not updated after an account termination or username change. This leads to cron failure notifications because /usr/local/cpanel/bin/autossl_check_cpstore_queue can't find the user:
Cpanel::Exception::UserNotFound/(XID pj5qap) You do not have a user named “user”.
at /usr/local/cpanel/Cpanel/Exception.pm line 73.
Cpanel::Exception::create("UserNotFound", HASH(0x3c9fa58)) called at /usr/local/cpanel/Cpanel/Config/LoadCpUserFile.pm line 295
Cpanel::Config::LoadCpUserFile::_load("user", undef, "if_missing", "die") called at /usr/local/cpanel/Cpanel/Config/LoadCpUserFile.pm line 69
Cpanel::Config::LoadCpUserFile::load_or_die("user") called at bin/autossl_check_cpstore_queue.pl line 111
bin::autossl_check_cpstore_queue::run() called at bin/autossl_check_cpstore_queue.pl line 56
The temporary workaround is to manually remove the entries from the /var/cpanel/autossl_queue_cpanel.json file with a text editor via the command line. I'll update this thread once the resolution is published.
