Cannot rebuilt /etc/apt/trusted.gpg keyring properly : gpg: [don't know]: invalid packet (ctb=01)

I cannot rebuilt the /etc/apt/trusted.gpg keyring properly :

$ sudo rm /etc/apt/trusted.gpg
rm: remove regular file ‘/etc/apt/trusted.gpg’? y
$ sudo apt-key update 2>&1 | egrep "gpg:.*(invalid|failed)"
gpg: [don't know]: invalid packet (ctb=01)
gpg: keydb_get_keyblock failed: eof
gpg: [don't know]: invalid packet (ctb=01)
gpg: keydb_get_keyblock failed: eof
gpg: [don't know]: invalid packet (ctb=01)
gpg: keydb_get_keyblock failed: eof
gpg: [don't know]: invalid packet (ctb=01)
gpg: keydb_get_keyblock failed: eof
$ apt-key list >/dev/null
gpg: [don't know]: invalid packet (ctb=01)
gpg: keydb_search_next failed: invalid packet

EDIT 1 : I found this pb. was related to the keyrings in /etc/apt/trusted.gpg.d/, so I recreated them with add-apt-repository :

$ sudo mv /etc/apt/trusted.gpg.d /etc/apt/trusted.gpg.d.BACKUP
$ sudo mkdir /etc/apt/trusted.gpg.d
$ time awk -F / '/^deb .*ppa.launchpad.net/{print "sudo add-apt-repository -y ppa:"$4"/"$5}' /etc/apt/sources.list.d/*.list | sh -x

After some digging, I found that GnuPG v1 (which a dependency of the Ubuntu Trust APT packet) cannot handle more than 40 keyrings, that it so say, it cannot handle more than 39 keyrings in /etc/apt/trusted.gpg.d/ (according to this : https://askubuntu.com/a/508337/426176 and that : https://www.mail-archive.com/[email protected]/msg23302.html)

EDIT 2 : I have removed 10 duplicate keys in /etc/apt/trusted.gpg.d/ :

Is adding all my gpg launchpad ppa keys in the same /etc/apt/trusted.gpg keyring the only solution, it seems a little less ordered ?

EDIT 3 : Now I have 16 extra (rejected) keys in /etc/apt/trusted.gpg.d/, so I'm gonna move them to the /etc/apt/trusted.gpg keyring :

$ apt-key list 2>&1 >/dev/null | awk -F"[\`']" '/resource limit/{print "sudo apt-key add "$2" 2>/dev/null ; sudo \\rm -vf "$2}' | sh -x

Not to be harsh but you have way too many ppas and you need to get rid of some to fix your problem. Sorry :(

A lot of people use ppa-purge but I'm not 100% sure that this will remove the keys so you will have to check after you purge the ppa to make sure the key is gone as well.

Try and see if some ppas are using the same key number. If so, then you can delete the duplicate keys to help you get your number under 40. The Ubuntu mate ppas probably use the same key so you could probably delete a duplicate if you find one.

Additionally, some ppas like the webupd8 ppas (which probably also use the same key) are no longer maintained and so you can remove these ppas. Unfortunately, the webupd8 ppas haven't been updated since 2017.

The skunk pepperflash ppa hasn't been updated since 2016 and besides, you don't even need a pepperflash installer ppa because all you have to do is enable the Canonical repository in Software & Updates and then run: sudo apt update; sudo apt install adobe-flashplugin. Also see here.

The privoox ppa also hasn't been updated since 2016.

These are only the ppas that I have used Google to check. You will need to use Google to check the rest of these yourself to see which ppas are still active and which ones are no longer maintained.
