Pacman: opencascade74 and opencascade are in conflict while upgrading

Question

when I run sudo pacman -Syu pacman throws this error:

:: Synchronizing package databases...
 core is up to date
 extra is up to date
 community-testing is up to date
 community is up to date
 multilib is up to date
:: Starting full system upgrade...
resolving dependencies...
looking for conflicting packages...
error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: opencascade74 and opencascade are in conflict

I tried to clear cache with sudo pacman -Sc but error remains

When I try to remove opencascade package but:

sudo pacman -R opencascade
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: removing opencascade breaks dependency 'opencascade' required by freecad

How can I get around this error to upgrade my system ?

Answer 1

I solved it ignoring freecad first:

sudo pacman -Syu --ignore freecad

and then run upgrade without ignore flag sudo pacman -Syu:

:: opencascade74 and opencascade are in conflict. Remove opencascade? [y/N]

Confirm with yes

Now you have upgraded your system without any conflicts.
