If your running a x64 bit Ubuntu or other Linux and find USB transfers hang at the end apply this fix:

echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes

I suggest you edit your /etc/rc.local file to make this change persistant across reboots.

sudo nano /etc/rc.local

• Install Wireguard aptitude install wireguard
• create keys for your node
  • cd /etc/wireguard/
  • umask 077; wg genkey | tee wg0.key | wg pubkey > wg0.pub

Next make your config touch /etc/wireguard/wg0.conf, inside you can put this:

The problem

When you attach a file, roundcube tells you: File upload failed

I understand you

When you fixed all what you think and even fullfilled some php vars like base_dir and pack of upload* variables and you still see empty files and you wanna remove this #$%^!, just relax and..

Solution

In a config file keep/add in active plugins filesystem_attachments and remove database_attachments (if you had it).

They can't work together and attachements needs at least a filesystem_attachments.

• install dnsmasq (2.78+, cause 2.72 is bugged with certain DNS, including cloudflare)
• /etc/dnsmasq.conf:

port=53
listen-address=127.0.0.1
interface=lo
bind-interfaces
dnssec
dnssec-check-unsigned
trust-anchor=.,19036,8,2,49AAC11D7B6F6446702E54A1607371607A1A41855200FD2CE1CDDE32F24E8FB5
