sudo: sorry, you are not allowed to set the following environment variables

I have created few aliases, that I source to shell: alias apti="apt-fast install -y" alias aptr="apt-fast remove -y" alias aptp="apt-fast purge -y" alias apts="aptitude search" alias aptu="sudo dpkg --configure -a; apti -f; apt-fast update; apt-fast upgrade -y; apt-fast full-upgrade -y; apt-fast autoremove -y" and then added exceptions to /etc/sudoers: # # This file MUST be edited with the 'visudo' command as root. # # Please consider adding local content in /etc/sudoers.d/ instead of # directly modifying this file. # # See the man page for details on how to write a sudoers file. # Defaults env_reset Defaults mail_badpass Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin" # Host alias specification # User alias specification # Cmnd alias specification # User privilege specification root ALL=(ALL:ALL) ALL # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL # Allow members of group sudo to execute any command %sudo ALL=(ALL:ALL) ALL # See sudoers(5) for more information on "#include" directives: #includedir /etc/sudoers.d Cmnd_Alias APT=/usr/local/bin/apt Cmnd_Alias DPKG=/usr/bin/dpkg Cmnd_Alias APTGET=/usr/bin/apt-get Cmnd_Alias APTITUDE=/usr/bin/aptitude Cmnd_Alias APTFAST=/usr/sbin/apt-fast Cmnd_Alias PM_SUSPEND=/usr/sbin/pm-suspend myuser ALL=(ALL:ALL) NOPASSWD: APT, DPKG, APTGET, APTITUDE, PM_SUSPEND, APTFAST and it worked fine for years. But few weeks ago (linux mint update?) it started giving me error. $ apti iridium-browser sudo: sorry, you are not allowed to set the following environment variables: DEBUG, LCK_FILE, DOWNLOADBEFORE, _APTMGR, APTCACHE, DLDIR, DLLIST, LISTDIR, _MAXNUM, _MAXCONPERSRV, _SPLITCON, _MINSPLITSZ, _PIECEALGO, aptfast_prefix, APT_FAST_TIMEOUT In /etc/sudoers.d I have two files: README and mintupdate. I have not edited any of them. Only not commented lines are: Cmnd_Alias UPDATE = /usr/lib/linuxmint/mintUpdate/checkAPT.py ALL ALL = NOPASSWD:UPDATE As far as I can see, I am not setting any environment variables that are lissted. What am I doing wrong?
