Hi,

,,how 2 solve aptitude/apt/apt-get Could not resolve 'deb.devuan.org'
with IPv4: paste in: " echo 'Acquire::ForceIPv4 "true";' | sudo tee \
/etc/apt/apt.conf.d/99force-ipv4 ", or, as root, paste in:
" echo 'Acquire::ForceIPv4 "true";' >/etc/apt/apt.conf.d/99force-ipv4 "

..either of these 2 commands will create a new file 99force-ipv4
with content that will force aptitude et al to only use IPv4.

..source: Chimarea box with apt* dns fails (with (Debian's?) IPv6) and

Scenarios always come in sets of three:
best case, worst case, and just in case.
