Sometimes when updating or install packages, guix encounters conflicts. It's usually smart enough to fix it by itself.
That said, conflicts seems to be a telltale sign of bad packaging (e.g. duplicate files in a package and its inputs). Presently guix reports 3 conflicts on my install: --8<---------------cut here---------------start------------->8--- warning: collision encountered: /gnu/store/9hddxnv7q3q819axyw0yngzppmrgmjfi-mesa-17.3.8/lib/pkgconfig/wayland-egl.pc /gnu/store/2w8lhl8hyvciy3hb0h2r0mbhx7pmniy1-wayland-1.15.0/lib/pkgconfig/wayland-egl.pc warning: choosing /gnu/store/9hddxnv7q3q819axyw0yngzppmrgmjfi-mesa-17.3.8/lib/pkgconfig/wayland-egl.pc warning: collision encountered: /gnu/store/9hddxnv7q3q819axyw0yngzppmrgmjfi-mesa-17.3.8/lib/libwayland-egl.la /gnu/store/2w8lhl8hyvciy3hb0h2r0mbhx7pmniy1-wayland-1.15.0/lib/libwayland-egl.la warning: choosing /gnu/store/9hddxnv7q3q819axyw0yngzppmrgmjfi-mesa-17.3.8/lib/libwayland-egl.la warning: collision encountered: /gnu/store/nf6py3ddvk8nsqxg7jlg0kmiqjigiqgw-gtk-icon-themes/share/icons/hicolor/icon-theme.cache /gnu/store/mg1ilfq7ajcsk12kanzsbb8jhgv7g5vm-gtk+-3.22.29/share/icons/hicolor/icon-theme.cache warning: choosing /gnu/store/nf6py3ddvk8nsqxg7jlg0kmiqjigiqgw-gtk-icon-themes/share/icons/hicolor/icon-theme.cache --8<---------------cut here---------------end--------------->8--- Let's lookup some referrers: --8<---------------cut here---------------start------------->8--- > guix gc --referrers /gnu/store/mg1ilfq7ajcsk12kanzsbb8jhgv7g5vm-gtk+-3.22.29 > | grep gtk-icon-themes$ /gnu/store/4mlzz64zl3a78xg9f2dxzmr1yyhkmif4-gtk-icon-themes /gnu/store/bgrh681a53xci0736b3ljc4jxf59x3dq-gtk-icon-themes /gnu/store/dvbbd7j5932638s3s60ajrk8sh9hvjwa-gtk-icon-themes /gnu/store/nf6py3ddvk8nsqxg7jlg0kmiqjigiqgw-gtk-icon-themes /gnu/store/qmq2zkp9cm57ginsg3k1qy5p06cb904k-gtk-icon-themes /gnu/store/w2pyc6x9vlb92w9wxjj0kn2464185h7d-gtk-icon-themes /gnu/store/yxilw237d6k6fffyga26h1by4cldkxf1-gtk-icon-themes /gnu/store/zizsh56zfj75xhgphn6myql3n1cnr8cm-gtk-icon-themes > guix gc --referrers > /gnu/store/nf6py3ddvk8nsqxg7jlg0kmiqjigiqgw-gtk-icon-themes /gnu/store/ki1c671fy8p1phvdlq9h6ff1nngynchj-profile --8<---------------cut here---------------end--------------->8--- So if I get it right, gtk-icon-themes is an automatically generated store items for each profile and it duplicates a file found in gtk+-3.22.29.

So far so good. Same question: is this a packaging mistake? Or, as a workaround, is it possible _not_ to install Wayland? -- Pierre Neidhardt When a fly lands on the ceiling, does it do a half roll or a half loop?
