A lot of apps give this error while I try to install/build them with pamac.
I have 2 partitions: / and /home, owned by root and user.
Some example application that failed (there’s a lot more):
ln: failed to create symbolic link '/.nvm/nvm.sh': Read-only file system ==> ERROR: A failure occurred in build(). Aborting... Finished with result: exit-code Main processes terminated with: code=exited/status=4
ls -la /.nvm
user@user:~$ ls -la /.nvm/ total 8 drwxr-xr-x 2 root root 4096 20 oct. 20:57 .
