[Solved] gcc7: /usr/bin/gcc-7 exists in filesystem

Hi,

I'm trying to

pacman -Suy

and I get, besides 153 other packages, an update of gcc-7:

gcc7-7.3.1+20180406-2
gcc7-libs-7.3.1+20180406-2

But this fails:

error: failed to commit transaction (conflicting files)
gcc7: /usr/bin/gcc-7 exists in filesystem
Errors occurred, no packages were upgraded.

So what did help to get all the rest updated was

pacman -Suy --ignore gcc7

but after this completed successfully (cuda was skipped by the above step as pacman reports it to depend on gcc7):

:: Synchronizing package databases...
 core is up to date
 extra is up to date
 community is up to date
:: Starting full system upgrade...
resolving dependencies...
looking for conflicting packages...

Packages (3) cuda-9.2.88.1-2  gcc7-7.3.1+20180406-2  gcc7-libs-7.3.1+20180406-2

Total Installed Size:  2744.65 MiB
Net Upgrade Size:       380.50 MiB

error: failed to commit transaction (conflicting files)
gcc7: /usr/bin/gcc-7 exists in filesystem

any thoughts on this?

In general read the guidance in https://wiki.archlinux.org/index.php/Pa … 9.22_error

If you've determined the overwrite to be safe you could make use of the new pacman option.

pacman -Syu --overwrite usr/bin/gcc-7

Re: [Solved] gcc7: /usr/bin/gcc-7 exists in filesystem

ok, thanks for the hint and the link to the guide. I did as suggested:

$ pacman -Qo /usr/bin/gcc-7

error: No package owns /usr/bin/gcc-7

I dunno how this happened, but anyways, the suggested

pacman -Syu --overwrite usr/bin/gcc-7

then did the trick:

$ pacman -Qo /usr/bin/gcc-7

/usr/bin/gcc-7 is owned by gcc7 7.3.1+20180406-2
